PREFACE

This Occupational Survey Report (OSR) presents the results of a detailedAir Force occupational survey of the Aerospace Propulsion career ladder:

AFSC 454XOA - Aerospace Propulsion (Jet Engines) (Formerly AFSC 426X2 -Jet Engine Mechanic)

AFSC 454XOB - Aerospace Propulsion (Turboprop and Turboshaft Propulsion)(Formerly AFSC 426X3 - Turboprop Propulsion Mechanic)

AFSC 45490 - Aerospace Propulsion Superintendent (Formerly AFSC 42699 -Aircraft Propulsion Superintendent)

The specialties covered in this OSR were involved in a direct classificationconversion as of 31 October 1988. All data on these specialties, however,were collected prior to the conversion. Thus, to avoid confusion, all datadisplays and discussion throughout the OSR will continue to use the old clas-sification numbers. Authority for conducting occupational surveys is con-tained in AFR 35-2. Computer products used in this report are available foruse by operations and training officials.

The survey instrument for this project was developed by Mr DonaldCochran, Inventory Developer. Technical Sergeant Joseph Seitz and Mr WayneFruge provided computer support for the project. First Lieutenant Jose E.Caussade, Occupational Analyst, analyzed the data and wrote the final report.Administrative support was provided by Mr Richard G. Ramos. This report hasbeen reviewed by Lieutenant Colonel Charles D. Gorman, Chief, Airman AnalysisBranch, USAF Occupational Measurement Center.

A Training Requirements Analysis (TRA) is being accomplished in conjunc-tion with this OSR. The TRA will provide a comprehensive data base in supportof career ladder training decisions. The TRA consists of three sections: (a)System Overview - an overall perspective of career ladder training; (b) TaskAnalysis - consisting of detailed training decision data for career laddertechnical tasks; and (c) Training Requirements/Recommendations - giving recom-mendations on what should be trained, when training should occur, and wheretraining should be provided.

Copies of this report are distributed to Air Staff sections, major com-mands, and other interested training and management personr-i (see Distribu-tion on page i). Additional copies are available upon rL ,ie't to the (SAFOccupational Measurement Center, Attention: Chief, Occuj. nal AnalysisDivision (OMY), Randolph Air Force Base, Texas 78150-5000.

SUMMARY OF RESULTS

1. Survey Coverage: Survey results are based on responses from 5,427 AFSC426X2, 426X3, and 42699 personnel. The sample was broken down into 4,206 AFSC426X2 individuals and 1,010 AFSC 426X3 career laddpr members. Additionally,211 9-skill level (AFSC 42699) personnel participated in the survey sample.

2. Specialty Structure: Three major technical jobs, accounting for 59 per-cent of the total sample, and several smaller, more specialized jobs wereidentified. While diverse in the number of functional areas, personnelexhibit a good degree of uniformity in many of the tasks performed across thetwo AFSCs. Variations within these jobs were easily distinguished by careerladder and type of engine.

3. Career Ladder Progression: Each career ladder has 3- and 5-skill levelpersonnel essentially performing the same functions. At the 7-skill level,while supervisory tasks are the most commonly performed tasks, most of theirtotal job time is still spent in "hands on" technical duties. AFSC 42699 per-sonnel have a very managerial job description consisting of many inspectingand evaluating type tasks. AFR 39-1 Specialty Descriptions are generallydescriptive of the career ladder's responsibilities. Consideration should begiven to removing maintenance of turbojet missile engine functions from theDescriptions.

4. Training Analysis: Due to the number of specific areas employing AFSC426X2/X3 personnel, many items in each career ladder's STS and POI matched totasks performed by low percentages of career ladder groups. Strict adherenceto appropriate regulations would obligate these areas be removed from thetraining documents. Enough latitude is provided in the regulations, however,to set up alternative means of reviewing these documents. Subject-matterexperts are encouraged to closely review these documents, using OSR data, todetermine document areas needing imprcvement. Three-skill level proficiencycodes in the STSs need to be examined to ensure good representative 3-skilllevel formal training is being provided. Additionally, each training documenthad several unreferenced tasks needing examination for possible inclusion.

5. Job Satisfaction: High levels of job satisfaction were noted in bothcareer ladders. A few jobs, such as Technical Order and Nonpowered SupportEquipment Personnel, displayed lower job satisfaction indicators than mostother jobs.

6. Implications: The propulsion specialty exhibits some diversity in thefunctional areas in which personnel are employed. This affects the trainingdocuments which revealed several areas matched to tasks performed by low per-centages of career ladder groups. A number of methods for reviewing thesedocuments are discussed.

OCCUPATIONAL SURVEY REPORTJET ENGINE/TURBOPROP PROPULSION

(AFSC 426X2/426X3, 42699)

INTRODUCTION

This report summarizes the results of an occupational survey of the JetEngine/Turboprop Propulsion career ladders (AFSCs 426X2/426X3 an 42699). Asa result of October 1988 Rivet Workforce initiatives, the two career laddershave converted into one multishred career ladder (AFSC 454XOA/B, AerospacePropulsion). At the time of this report, however, the major result of thisinitiative has been an AFSC number change. Since the data were collectedprior to the conversion, the narrative and all tables will use the old classi-fication numbers. - * *. - , IJ

The study was initiated to update career ladder task , to assist' inreclassification actions, and to update career ladder training documents. '''

Additionally, the survey will identify what "engine monitoring system" and :7"engine management" tasks are being performed. The previous OSR was publishedin April 1982.

BackQround

AFSC 426X2 (Jet Engine) personnel functions include inspecting, removing,installing, assembling, disassembling, troubleshooting, repairing, servicing,testing, and modifying turbojet, turbofan, and modular turbofan aircraftengines; auxiliary power units (APU); small gas turbine engines; and otherassociated equipment. AFSC 426X3 (Turboprop) personnel perform many of thesame functions on turboprop and turboshaft aircraft engines, propellers, APUsand other associated equipment.

Initial 3-skill level training for AFSC 426X2 personnel is provided atChanute AFB in a 9-week, 3-day course. Students are instructed in jet engineoperating principles, engine change, adjustments and conditioning of jetengines and systems, and other jet engine repair aspects. At the start ofBlock III, trainees split into two different avenues. One track teaches theF1O0 engine, while the other track instructs on the J57 engine. Regardless ofthe training platform utilized, both tracks cover the same materiel in theinstruction Block. After completion, students often go into engine-specifictraining on engines such as J85, TF33, and FlOO-PW-220 at the tech school.

AFSC 426X3 initial 3-skill level training is also conducted at ChanuteAFB in a 10-week, 2-day course. In addition to training on repair and mainte-nance of turboprop engines, propeller maintenance is instructed. Airmenassigned to helicopter units get follow-on training at the tech school onhelicopter turboshafts.

SURVEY METHODOLOGY

Survey Development

Data for this survey were collected using USAF Job Inventory AFPT90-426-842, dated March 1988. After reviewing pertinent career ladder publi-cations and tasks from previous survey instruments, the inventory developerprepared a preliminary task list. This task list was then refined and vali-dated through personal interviews with 191 subject-matter experts at 17 opera-tional bases and one training base to ensure a comprehensive sample of thevarious functions performed within the AFSC 426X3/X3 career ladders. Thelocations selected for visits and the reasons for their selection are listedbelow:

The final job inventory consisted of 946 tasks, divided into 20 func-tional areas or duties. The inventory also contained a background sectionwhich includes questions on job title, mission, aircraft qualification, grade,and total active federal military service (TAFMS).

Survey Administration

From February through October 1988, survey control officers at Consoli-dated Base Personnel Offices worldwide distributed the inventory to AFSC426X2, 426X3, and 42699 personnel. Participants were selected from acomputer-generated mailing list provided by the Human Resources Laboratory.

To complete the survey, each incumbent first answered a series of back-ground questions, then marked the tasks he or she performed. Finally, theincumbent rated each task performed according to the relative time spent per-forming that task. Ratings range from 1 (a very small amount of time spent)to 9 (a very large amount of time spent). As part of the computer analysis,all of an incumbent's ratings are combined and the total is assumed to repre-sent 100 percent of the individual's time on the job. Each rating is thendivided by this total and multiplied by 100 to give the relative percent timespent for each task. Using these figures, analysis compares tasks in terms ofthe relative percent time spent performing them.

Survey Sample

With over 10,000 AFSC 426X2 individuals eligible to receive a surveybooklet, a random, stratified selection process was used to select career lad-der members as survey participants and to ensure a proportional representationof major commands (MAJCOM) and military paygrades in the sample. Due to thesmaller AFSCs 426X3 and 42699 career ladder sizes, all but those in training,hospital, or PCS status were selected to complete the job inventory. A totalof 6,907 incumbents were randomly selected to complete the job inventory.This list of eligible personnel included an accurate representation acrossMAJCOMs. Table 1 reflects the distribution by MAJCOM and career ladder ofpersonnel assigned to the career ladder as of April 1988, and of respondentsin the survey sample. The 5,427 respondents in the final sample represent 79percent of those receiving inventory booklets.

Task Factor Administration

In addition to collecting task performance data, part of the surveyadministration process involves col'ecting task factor ratings of task diffi-culty (TD) and training emphasis (TE). These ratings are collected fromsenior NCOs randomly selected to represent their career ladder and are proc-essed separately from task performance data.

Task difficulty is defined as the length of time required for the averagejob incumbent to learn to do a task. To complete the TD booklet, each seniorNCO rated inventory tasks with which they were familiar on a 9-point scaleranging from extremely low relative difficulty (a rating of 1) to extremelyhigh relative difficulty (a rating of 9). Separate ratings were computed foreach career ladder. The interrater reliability of the TD data provided by 88AFSC 426X2 NCOs was acceptable, as was the interrater reliability provided bythe 48 AFSC 426X3 NCOs. Each of these sets of TD ratings was adjusted to givea rating of 5.00 to a task of average difficulty, with a standard deviation of1.00. Tasks rated 6.00 and above are considered high in task difficulty. TheTD ratings provide a rank-ordered listing of the tasks in the inventory bydegree of difficulty.

Training emphasis refers to the importance of structured training(through resident technical schools, field training detachments, formal OJT,etc.) of particular tasks for first-enlistment personnel. Individuals com-pleting TE booklets rated tasks on a 10-point scale ranging from a blank (notraining emphasis) to 9 (extremely heavy training required). The TE ratingsprovide a rank-ordered listing of tasks from high to low training emphasis.As was the case with TD ratings, separate ratings were computed for eachshredout.

The interrater reliability for the 90 NCOs in the Jet Engine Propulsioncareer ladder was acceptable. The average TE rating was 1.72, with a standarddeviation of 1.33. Tasks rated above 3.05 are considered high in trainingemphasis for AFSC 426X2 first-termers. The 37 AFSC 426X3 TE raters also hadan acceptable interrater reliability, with an average TE rating of 1.59 and astandard deviation 1.37. Tasks above 2.96 are considered high in trainingemphasis for AFSC 426X3 first-enlistment personnel.

When used in conjunction with other information, such as percent membersperforming, TD and TE ratings can provide insight into training requirements.Such insight may help validate lengthening or shortening portions of instruc-tion supporting AFSC-needed knowledges or skills.

SPECIALTY JOBS(Career Ladder Structure)

An important function of the USAF Occupational Analysis Program is exam-ining a career ladder's structure. Based on incumbent responses to the sur-vey, analysis identifies groups of incumbents spending similar amounts of time

5

performing similar tasks. Individuals performing many of the same tasks, andspending similar amounts of time on those tasks, group together to describe ajob performed in the career ladder. In this way, analysis identifies thebasic structure of the career ladder in terms of the jobs performed and theirrelationship to each other. This analysis provides a foundation for reviewingother aspects of the career ladder, such as personnel classification, AFR 39-iSpecialty Descriptions, and training considerations.

Specialty Structure Overview

The AFSC 426X2/X3 career ladders are diverse in the functional areas theyencompass. Just three technical jobs encompass 59 percent of the sample. Theremaining sample, however, is divided into 15 other smaller, more specializedjobs (not including the Supervisory Job). Airmen in both career ladders per-form many of the same tasks. Each career ladder's basic duties revolve aroundthe maintenance and repair of aircraft engines. Similarity between the twocareer ladders was thus great enough to warrant identifying jobs by functionalarea, as opposed to AFSC. Jobs will thus be listed as "Flightline Personnel,"for example, as opposed to "Jet Engine Flightline Personnel" and "TurbopropFlightline Personnel." Primary differences between the two career ladders liein engine-specific areas. For example, AFSC 426X2 personnel do not normallywork on propellers, while few AFSC 426X3 personnel perform tasks dealing withafterburners. Variations existed within many of the jobs, often by enginetype. Variations are defined as clearly i-'entifiable functions within a jobthat are no! different enough to be broken out into separate jobs. The threemajor jobs mentioned above are In-Shop, Flightline, and Test Cell Personnel.Many of the other identified jobs are smaller, more specialized areas, oftenfunctionally grouped in the career ladders under the shop or flightline areas.In the following discussion, the stage (STG) or group (GPO) number refers tocomputer-printed information. Figure 1 illustrates the jobs identified inthis survey.

Ninety percent of the survey respondents grouped into the above jobs.The remaining sample did not perform functions similar enough to grouptogether or performed so few tasks in the inventory that their job could notbe described.

Group Descriptions

The following paragraphs briefly describe the different jobs identifiedin the analysis. Table 2 provides selective background data on these jobs.For a more detailed listing of representative tasks and a summary of back-ground data on these jobs, see Appendix A.

I. CROSS UTILIZATION TRAINING (U PERSONNEL (STG0289). Personnel inthis job perform tasks outside the normal engine maintenance duties, Insteadof engine maintenance and repair, these individuals spend the majority oftheir total job time (58 percent) performing cross-utilization training tasks.These are tasks normally performed by personnel in other career ladders. ManyAFSC 426X2/X3 personnel perform these tasks as part of an initiative to betterutilize personnel and tasks on the flightline. This job averages a small num-ber of tasks (28 tasks). Representative tasks include:

Comparison of Specialty Jobs

As is readily evident from the above discussion, the propulsion specialtycontains a number of different jobs covering a wide variety of tasks. Severaltasks, nevertheless, were commonly performed by personnel in both the JetEngine and Turboprop specialties. Because of this task commonality, jobswithin the propulsion specialty were identified by functional area, ratherthan by AFSC. Within many of these functional areas, however, personnel ineach of the career ladders clearly separated b' AFSC into their own distinctvariations. The consolidation of the two propulsion specialties into theseoverall jobs should, therefore, not be viewed as a call to merge the two spe-cialties, since the two ladders distinctly separated by specialty and wouldassumedly separate by shreds.

The three major technical jobs identified in the career ladder were theIn-Shop, Flightline, and Test Cell Personnel jobs. Most of the other jobswere small, specialized shops often located within shop or flightline func-tional areas. Examples of specialized jobs often functionally located withinthe shop area include: Balance Shop, Afterburner/Augmentor Module, AccessoryRepair, Nonpowered Support Equipment, and SGT. Phase Dock Personnel, on theother hand, are usually functionally located under the flightline area.

-ie majority of variations identified within the specialty jobs (espe-cially in the In-Shop and Flightline Personnel jobs) centered around engines.Individuals in these variations were found performing tasks particular to spe-cific engine types.

Comparison to Previous Survey

The results of this survey were compared to the results of the list AFSC426X2/X3 survey, AFPT 90-426-424, dated April 1982. Overall, the previoussurvey reported findings similar to those stated in the present job structureanalysis. Both identified the three major technical jobs plus several othermore specialized jobs. The last survey, however, separated these jobs bycareer ladder. For instance, the 1982 survey featured a job of "FlightlineTurboprop Engine Maintenance Personnel" and another job of "Flightline JetEngine Maintenance Personnel," as opposed to just "Flightline Personnel."

The past survey also identified several jobs by different names. Themost notable is "Aircraft Servicing Personnel," which in the present surveyare called "Cross Utilization and Training (CUT) Personnel." One previouslylisted job, not identified in the present survey, was "QEC Kit Monitors.""Engine Monitoring Personnel," on the other hand, was not identified in theprevious survey. Further, "Phase Dock Personnel" and "Nonpowered SupportEquipment Personnel" are two jobs formerly identified as variations underlarger jobs. A final finding deals with the "Small Gas Turbine Personnel"job. The 1982 OSR had both AFSC 426X2 and 426X3 personnel within its SGT job,while the present study identified only AFSC 426X2 airmen in the job. Pocketsof AFSC 426X3 personnel performing these tasks were, nevertheless, found in

21

the sample, but did not group in the present "Small Gas Turbine Personnel"job. A complete listing corux ring the present and previously identified jobsis included in Table 3.

ANALYSIS OF 426X2/426X3 UAFSC GROUPS

In addition to analyzing the career ladder structure, examining skilllevels is helpful in understanding a career ladder. The DAFSC analysis com-pares skill levels, highlighting differences in the tasks performed at thedifferent levels. This information can be useful in examining how well vari-ous career ladder documents, such as AFR 39-1 Specialty Descriptions and theSpecialty Training Standards (STS), reflect what career ladder personnel areactually doing in the field.

A. AFSC 426X2 DAFSC Analysis: Three and 5-skill level personnel werecombined for purposes of this analysis. Both skill levels essentially performthe same functions, though some increase does occur in supervisory duties atthe 5-skill level. DAFSC 42672 personnel perform a job encompassing many ofthe tasks done at the more junior skill levels in addition to the supervisoryresorsib'lities that enter into their job descriptions. The distribution ofskil -Ievel members across each job is shown in Table 4. To give a sense ofthe progression through the skill levels, relative time spent in each duty byskill level is presented in Table 5.

The 2,720 airmen with a DAFAC of 42632 or 42652 comprise 65 percent ofthe total AFSC 426X2 sample. They perform a very technical job primarilydealing with performing general aircraft engine maintenance tasks (which com-prise 56 percent of their total job time). A number of their tasks involveremoving or installing and inspecting various engine components (see Table 6).The majority of 3- and 5-skill level personnel work in the In-shop or Flight-line jobs.

The DAFSC 42672 group consisted of 1,486 individuals, accounting for 35percent of the total AFSC 426X2 sample. Supervisory and administrative areasare the most commonly performed tasks of these career ladder members. They,however, still spend the majority of their total job time in technical duties.Only 32 percent is spent in traditional supervisory duties. Many of their toptechnica] tasks involve inspecting engine components. They thus perform manyof t ; technical tasks accomolished by 3- and 5-skill personnel, in additionto the supervisory tasks in their job description. Jobs employing the most7-skill level qualified individuals include Flightline, Supervisory, andTn-shop. A number of their representative tasks are presented in Table 7.

B. AFSC 426X3 DAFSC Analysis: A great many similarities exist betweenthe AFVC 426X3 and 42!X2 DAFS aralyses. As with the AFSC 42632/52 DAFSCanalysis, the AFSC 426X3 3- and 5-skiIl level analysis will be combined. Nota great deal of difference was n ,ted in either of their singular respon-sibilities. DAFSC 42673 personnel, like their DAFSC 42672 counterparts,

perform both a technical and supervisory job. Data on skill-level distribu-tion across jobs and relative time spent in duties are shown in Tables 4 and8, respectively.

The sample captured 585 DAFSC 42633/53 individuals, accounting for 58percent of the total AFSC 426X3 sample. Most of their responsibilities arevery technical, primarily dealing with both general aircraft engine and pro-peller maintenance tasks. These two duties account for 62 percent of theirtotal job time. Like the AFSC 426X2 junior skill levels, many of their tasksinvolve removal or installation of engine components (see Table 9). Most workin the Flightline job.

DAFSC 42673 personnel accounted for 42 percent of the total AFSC 426X3sample, numbering 425 members. Though supervisory tasks are clearly evidentin their job description, these areas only account for 25 percent of theirtotal job time. Their job is still primarily technical in nature. Many oftheir top technical tasks deal with inspecting engine components (see Table10). Seven-skill level members thus perform both the technical tasks dbne bythe 3- and 5-skill levels and the supervisory tasks that go along withincreased experience and seniority in the career ladder. The majority ofthese skill level members also work in the Flightline job.

C. DAFSC 42699 Analysis: These 211 individuals make up the most seniorgroup in the survey sample. They have shifted their job duties from primarilyworking on technical tasks to performing many of the managerial functions ofthe career ladder. Several of their top tasks deal with inspecting and evalu-ating, which accounts for 27 percent of their total job time (see Table 11).Their overall supervisory duties account for 71 percent of their total jobtime. They are primarily found in the Supervisory job (Table 4), but alsomake up 58 percent of the small Higher Headquarters Personnel job. A listingof their representative tasks is found in Table 12.

AFR 39-1 SPECIALTY DESCRIPTIONS FOR AFSCs 454XOA/B AND45490 (AFSCs 426X2/X3, 42699)

Occupational survey data are also used to examine classification issues.By comparing those jobs performed in a career ladder to the Specialty Descrip-tions, judgments can be made about the Descriptions' completeness andaccuracy.

AFR 39-1 Specialty Descriptions are intended to give a very broaddescription of the responsibilities held by the various skill levels within acareer ladder. The most recent AFR 39-1 in the propulsion career ladder(effective 31 October 1988), specifies the new AFSC 454XOA/B and 45490 desig-nations. Though this study has used the former propulsion AFSC designations,for purposes of this analysis, the latest AFR 39-1 for AFSC 454XOA/B will bereviewed.

When compared to survey data, the AFR 39-1 Specialty Description for theAerospace Propulsion Specialist (DAFSCs 45410, 45430, 45450), dated 31 October1988, accurately reflects the duties and tasks being accomplished at thoseskill levels. Performing the various inspections and repairs on jet engitles,turboprops, and turboshafts is well covered for both shreds. One job identi-fied in the survey and not clearly covered in the Duties and Responsibilitiessection is the Engine Management job. A recommended extractior from the Spe-cialty Description is reference to turbojet missile engines. Though no tasksin the inventory specifically deal with these functions, conversations withsubject-matter experts have indicated few propulsion specialty personnel work-ing in these areas.

The Aerospace Propulsion Technician (DAFSC 45470) Specialty Description,dated 31 October 1988, is also well supported by survey data. The primarilytechnical nature of their job is clearly evident in the description. Turbojetmissile engines are still mentioned in this description, however, and shouldbe considered for deletion.

The AFR 39-1 Specialty Description for Aerospace Propulsion Superintend-ent (DAFSC 45490 and CEM Code 11300), dated 31 October 1988, generally por-trays the managerial aspects of these skill levels. These are the managers ofthe career ladder, with many responsibilities in those areas. There is againmention of turbo engines installed on missiles, which has been recommended forremoval from the specialty description. An additional area to consider remov-ing involves the comment on the technical functions performed by these indi-viduals. They are listed in the Duties and Responsibilities section astroubleshooting and isolating malfunctions on engines, propellers and reldtedsystems. Very few at this level, however, actually perform these tecnnicalduties.

AFSCs 426X2 AND 426X3 TRAINING ANALYSIS

Information gathered from occupational survey data is also used to assistin the development and review of formal training programs or training docu-ments such as STSs and Plans of Instruction (POI). A particularly importantfactcr used in analyzing these training documents is the percentage of anappropriate group, such as first-enlistment (1-48 months TAFMS) personnel,performing tasks. In addition, the secondary task factors of TE and TD rat-ings (as explained in the Task Factor Administration section) provide usefulinformation.

Technical school personnel have matched nonmanagerial inventory tasks toappropriate STS and P0I sections to facilitate the use of occupational surveydata in ascertaining the relevance and completeness of these documents. Com-puter listings which display the STS or POI with matched tasks and survey dataare used in the analysis to show which sections of the STS or POI are mostrelevant to a career ladder. Survey data may also be used to show which tasksnot matched to these documents may need to be included due to the extent towhich they are performed in a career ladder and their importance to training.

36

To aid in any further detailed review of training documents, computer productdisplays have been forwarded to the technical school. In addition to a sum-mary of that information, this section contains an analysis of the first-enlistment personnel in each AFSC. Figures 2 and 3, respectively, display thedistribution of AFSCs 426X2 and 426X3 first-enlistment personnel across thejobs discussed in the SPECIALTY JOBS section of this report.

Training Emphasis and Task Difficulty Data

The objective of collecting TE and TD ratings is to develop rank-orderedlistings of tasks in terms of importance for first-enlistment training and interms of difficulty. A listing of training emphasis and task difficulty dataare included for each AFSC's tasks in Tables 13-16. (For a more detailedexplanation of both types of ratings, see Task Factor Administration in theSURVEY METHODOLOGY section.) Tasks performed by moderate to high percentagesof personnel may warrant resident technical training. TE and TD ratings, com-posed of the opinions of experienced career ladder personnel, are secondaryfactors that may assist training developers in deciding which tasks should beemphasized for entry-level training. Those tasks receiving high task factorratings, but performed by low percentages of first-enlistment personnel, maybe more appropriately planned for OJT prog-ams within the career ladder. Lowtask factor ratings may highlight tasks best left out of training for new per-sonnel, but this decision must be weighed against percentages of personnelperforming the tasks and other task considerations. A final product useful inmaking training decisions is the Automated Training Indicator (ATI). ATItakes first-enlistment, TE, and TD data and computes training decisions basedon Atch 1, ATCR 52-22.

AFSC 426X2 Training Issues

A. AFSC 426X2 First-Enlistment Personnel. First-enlistment AFSC 426X2personnel account for 36 percent of the Jet Engine sample, with 1,526 members.Personnel in this career ladder group perform a largely technical job consist-ing primarily of general aircraft maintenance tasks. Performing this dutyaccounts for 61 percent of their total job time. Many of their tasks involveremoving or installing and inspecting engine system components. Forty percentstart their career in the In-Shop Personnel job (see Figure 2). They performa job averaging 82 tasks. A list of representative tasks is included in Table17.

B. Equipment. The AFSC 426X2 career ladder is responsible for themaintenance of a number of different engines and their personnel use severaldifferent kinds of test and support equipment in performing their jobs. Sur-vey data can point out which engines and equipment are most used and by whatgroup. This information can then be used by training specialists to determinewhich types of engines and equipment should be emphasized for first-termtraining. Table 18 displays those pieces of equipment utilized by 10 percentor more of first-enlistment personnel. Table 19 exhibits the percentages offirst-enlistment and DAFSC groups utilizing the various engines maintained inthe career ladder. A full computer listing of all engine and equipment items,

C. AFSC 454XOA (426X2) Specialty Training Standard (STS). An STS isintended to provide comprehensive coverage of tasks performed by career ladderpersonnel. For purposes of this analysis, the most recent STS, written sincethe Rivet Workforce conversion, was reviewed. To assess the effectiveness ofthe AFSC 454XOA STS, dated October 1988, STS sections were compared to surveydata from career ladder groups, such as TAFMS and DAFSC groups. Sections con-taining managerial and general information areas were not reviewed. In addi-tion to examining how well survey data supported STS items, 3-skill levelproficiency codes were examined to determine how well they correspond tofirst-enlistment airmen percent performing levels. Lastly, analysis exploredareas lacking coverage in the STS and possibly warranting inclusion.

The diversity of jobs in the career ladder (as explained earlier) hasresulted in several STS items not being supported by OSR data. A career lad-der spread across a multitude of jobs results in several tasks being specificto only a few jobs. The criterion set forth in AFR 8-13 (dated 1 August 1986)and AFR 8-13/ATC Supplement 1 (dated 2 March 1987) for STS review calls foritems in the STS to be performed by at least 20 percent of a career laddergroup, such as skill level, to justify inclusion. Because of the number ofdifferent functions being performed by jet engine personnel, several did notmeet this criterion. The majority of these STS items were in Paragraph 15 -MAINTENANCE OF JET ENGINES and Paragraph 16 - ENGINE BLOCK TESTING. Most inParagraph 15 deal with the repair of various engine components.

The number of STS items not meeting the minimum 20 percent performingstandard is too numerous to discuss in great detail and involve a number ofimportant career ladder functional areas. Those matched to tasks performed byunder 20 percent of career ladder groups are included in Appendix B. As seenfrom this listing, though several may indeed warrant removal from the STS, anumber of others should not be excluded from the STS without further review.An STS is a career ladder-wide document and should include functions beingperformed by career ladder members. Thus, if a job is being done in a spe-cialty, it could be argued that the job should be covered in the STS, eventhough less than 20 percent perform associated tasks.

AFR 8-13 does provide some latitude in determining whether or not an STSitem remains if not performed by 20 percent or more of one of the criteriongroups. In career ladders whose diversity (or other factors) makes a 20 per-cent cutoff unrealistic, STS developers can justify and establish an alternatecutoff point and document their rationale. The following are some suggestionsthat ATC training personnel and career ladder functional managers can apply tomake alternative approaches to the STS:

(1) Lower the 20 percent cutoff rule to a level moreappropriate to the features of the career ladder, givingrationale for the change.

46

(2) Use other OSR data to justify inclusion, such as highTE or TD ratings.

(3) Insert a line entry in the STS for each career ladderfunction, regardless of percent performing. Then, usingthis more broadly defined approach by functional area,apply the provisions of AFR 8-13, Section B, paragraph 12to create an Air Force Job Qualification Standard todescribe each distinct job in the AFSC.

Reviewing the proficiency codes at the 3-skill level shows how well STScoding corresponds to first-enlistment airmen responsibilities. Items matchedto tasks performed by 30 percent or more of first-enlistment personnel nor-mally should have a task performance or task knowledge proficiency code at the3-skill level, unless additional factors dictate otherwise. This allows forinclusion of that item into 3-skill level formal resident training. SeveralSTS items with a 3-skill level proficiency code, however, were matched totasks performed by UNDER 30 percent of first-enlistment personnel. ATCR 52-22states that tasks should not be formally trained if performed by under 30 per-cent of first-enlistment personnel (unless additional factors dictate other-wise). Many of these items are in Paragraph 12 - GENERAL ENGINE MAINTENANCEand Paragraph 15. Table 20 includes several examples. Care needs to be takenin reviewing these STS items. Career ladder diversity may have also affectedmany of the low first-termer percentages. Subject-matter experts thus need tobe attentive in reviewing these items to determine if proficiency codes at the3-skill level should indeed be removed and thus eliminated from inclusion inthe training course.

An additional area of analysis involves examining tasks not matched toany STS element. Unreferenced tasks performed by at least 20 percent of acareer ladder group are performed to an extent great enough to be consideredfor inclusion in the STS. Table 21 lists several examples of tasks not refer-enced to any STS item. Subject-matter experts should examine these and otherunreferenced tasks to consider incorporating their functions in the STS.

D. AFSC 45430A (4263& Plan of Instruction. POI C3ABR45430A, being themost recent 3-skill level course, was examined for this analysis. This courseprimarily deals with instruction in the repair and maintenance of jet engines.Training includes operating principles, engine change, adjustments, and condi-tioning of jet engines and systems. Additional training is provided in theremoval, disassembly, inspection, repair, assembly, and installation of jetengines. Other information supplied includes ground safety practices, groundsupport equipment, operation of engine electrical systems, publications,forms, and maintenance concepts.

The course has two distinct Block III-Intermediate Maintenance sections.Section 000 uses the FIO engine as the training platform. Section 001, onthe other hand, uses the J57 engine for training. Both sections use theseengines for the general engine training and attempt to cover the same materialin each training platform.

With the assistance of training specialists from Chanute AFB, this POIwas matched to applicable inventory tasks. Computer printouts were then gen-erated to display the results of the matching for use in analyzing the ade-quacy of the POI. Only performance objectives were reviewed in this analysis,due to their relevance to task statements.

The diversity of the AFSC 426X2 career ladder has also affected thistraining document. A number of POI objectives were matched to tasks performedby less than 30 percent of airmen in their first 4 years. Most were found inBlock III. Additionally, several of the matched tasks had below average TEratings. The number of POI objectives not meeting the minimum 30 percent mem-bers performing criterion is too numerous to discuss in detail. They are,however, included in Appendix B for subject-matter expert consideration.

The above finding raises some issues that need addressing. The TrainingDecision Logic Table in ATCR 52-22, Attachment 1, recommends those areas per-formed by under 30 percent of first-termers not be included in formal train-ing. Taken at face value, this would lead to the elimination of much of the3-skill level course. In the same manner as the STS, however, other factors(such as career ladder diversity and criticality) may lead career ladder man-agers to decide to retain much of the training.

Nevertheless, training managers, career ladder managers, and subject-matter experts should perform an in-depth review of the entire course todetermine which, if any, of the POI objectives should be retained or elimi-nated. Where retention cannot be supported by OSR data, alternative justifi-cation rationale should be documented for future reference.

As with the STS, another part of the POI analysis involves examiningunreferenced tasks. These are areas that should be considered for courseinclusion due to high percentages of first-termers performing these tasks. Themajority deal with general aircraft engine maintenance tasks. Table 22 liststhese tasks. Training specialists should review unreferenced tasks performedby over 30 percent of first-job/first-enlistment personnel to determine ifthey should be included in common resident course training.

AFSC 426X3 Training Issues

A. AFSC 426X3 First-Enlistment Personnel. The 288 individuals in theirfirst-enlistment within AFSC 426X3 account for 29 percent of the sample ofturboprop maintenance respondents. Like their AFSC 426X2 counterparts, theseairmen perform a very technical job performing many "remove and install"engine component-type tasks. They also, however, perform several general pro-peller maintenance tasks. This function accounts for 16 percent of theirtotal job time. Fifty percent of AFSC 426X3 first-termers are employed in theFlightline Personnel Job (see Figure 3). This is contrary to AFSC 426X2first-termers who commonly work in the In-Shop Personnel job. AFSC 426X3first-termers perform a rather large job, averaging 115 tasks. Some of theseare included in Table 23.

B. Equipment. Similar to the AFSC 426X2 career ladder, AFSC 426X3 per-sonnel employ a wide variety of different tools and equipment and are respon-sible for several types of engines. Using survey data to identify highly usedpieces of equipment and engines can help tailor training requirements toensure knowledge in this area. Table 24 lists those pieces of equipment main-tained by significant percentages of first-term personnel. These should belooked at for technical school hands-on training. Table 25 displays thoseengines maintained by AFSC 426X3 first-term and DAFSC groups. A completelisting of career ladder equipment usage and engines maintained is included inthe Training Extract.

C. AFSC 454XOB (426X3) Specialty Training Standard (STS). The AFSC426X3 career ladder, also having been affected by Rivet Workforce, has theirlatest STS identified as AFSC 454XOB. This will be the one reviewed. Likethe A-shred STS, the B-shred Specialty Training Standard (dated August 1988)was compared to survey data to ascertain its soundness as a career ladder-widetraining document. Sections dealing with managerial and general informationareas were not reviewed. In addition to examining how well survey data sup-ported STS items, 3-skill level proficiency codes and possible areas excludedfrom the STS were also reviewed.

As mentioned above, an STS item is supported by OSR data if the inventorytasks matched to that item are performed by 20 percent or more of TAFMS and/orDAFSC groups. Using this criterion, the AFSC 454XOB STS, like its A-shredcounterpart, had several items not supported by survey data. In other words,several performance items were matched to tasks performed by under 20 percentof AFSC 454XOB personnel. Due to the number of items, they have been listedin Appendix B. Many of these items were in Paragraph 13 - MAINTENANCE OFTURBOPROP/SHAFT ENGINES, INCLUDING GAS TURBINE ENGINES with several referringto remove, install, and inspect items.

This lack of support could also have resulted from the diversity of jobsheld by AFSC 426X3 airmen. If such is indeed the case, an alternative method,as explained in the AFSC 454XOA STS analysis, is appropriate. An STS is acareer ladder-wide document, and if a specific function is being performed inthe field, it should be included in its STS, regardless of the percentage per-forming the function. One needs to remember, however, that the data collectedrepresent the tasks actually being performed by turboprop/shaft mechanics.Thus, if few individuals are performing a certain function, and it is notdeemed as a separate function of the career ladder, serious considerationnecds to be given Lo , itF fltup, in the STS. Each low-performingSTS item needs to be viewed with a critical eye from training specialists andcareer ladder managers to ensure that the STS is truly the best place to docu-ment that particular function. It is stressed that if an alternative route istraveled, proper justification and documentation be included for futurereference.

The AFSC 454XOB STS has a couple of issues dealing with 3-skill levelproficiency codes that need addressing. Three-skill level STS proficiencycodes were reviewed to ensure that items with high percentages of first-enlistment personnel performing were coded, thus allowing for structuredtraining. Examination of the STS revealed many items matched to tasks

performed by 30 percent or more of first-enlistment personnel with no 3-skilllevel proficiency code that would allow for structured training at that level.These are listed in Table 26. The majority of these items are in Paragraph18 - DIAGNOSE CAUSES OF MALFUNCTIONS. These areas, performed by high percent-ages of first-termers (and with high task factor ratings), and not taught inthe 3-skill level course, need to be considered for addition to the entry-level course.

The other proficiency code area examined were those items coded at the3-skill level (indicating formal training) matched to tasks performed by under30 percent of first-job/first-enlistment personnel (see Table 27). Due to thelow numbers of junior personnel making use of these skills and knowledges,training specialists need to consider dashing these items at the 3-skilllevel, resulting in removal from the course.

A final area of analysis involves examining tasks not matched to any STSitem. Tasks performed by 20 percent or more of a major group (i.e., TAFMS orDAFSC group), but unreferenced to the STS, should be considered for STS inclu-sion. Several tasks deal with performing general engine and propeller mainte-nance tasks. Examples of these and other unreferenced tasks are listed inTable 28. Subject-matter experts should review these tasks to see if anyareas need adding on to the STS.

D. AFSC 454XOB (426X3) Plan of Instruction. The latest DAFSC 42633 POIis C3ABR45430B, and will be the one reviewed in this analysis. This turbopropcourse shares many of the same topics as the jet engine course. Essentially,the course provides instruction on the disassembly, inspection, repair andassembly of turboprop engines. Propeller maintenance is also covered here,with training being given in the operation, removal, disassembly, inspection,repair, assembly, test and installation of hydraulically operated propellers,controls and assemblies. Other topics covered include ground safety prac-tices, ground support equipment, electrical fundamentals, publications, forms,and maintenance concepts.

The majority of POI objectives matched to OSR tasks was performed by 30percent or more of first-job/first-enlistment personnel, signifying generallygood support for the POI. Several objectives, however, were matched to tasksdone by under 30 percent of these criterion groups. The publication of an OSRis an excellent opportunity for training specialists to review these identi-fied unsupported objectives and consider their future in the trainingdocument.

A complete listing of these unsupported objectives is found in AppendixB. As can be seen, the majority of these objectives is found in Block IV -ENGINE REPAIR. A number of these deal with specific engine component partsworked on by relatively few individuals. Subject-matter experts need to exam-ine all the unsupported POI objectives to determine if they should indeed beremoved from the course so as to make it more representative of the tasks per-formed by airmen first entering the career ladder.

As with the STS, another part of the POI analysis involves examiningunreferenced tasks. Based on high percentages of first-termers performingthem, several tasks shold be considered for inclusion in the POI. Many ofthese tasks deal with performing general aircraft engine (Duty G) and generalpropeller (Duty H) functions. Table 29 lists examples of these tasks. Train-ing specialists should review these and other unreferenced tasks performed byover 30 percent of first-enlistment personnel to ascertain if they should beincluded in common resident course training. A complete listing is containedin the Training Extract, which has been forwarded to the technical trainingschool.

JOB SATISFACTION ANALYSIS

An examination of the job satisfaction indicators for each experiencegroup provides some understanding of factors which may affect the job perform-ance of AFSC 426X2/X3 personnel. Job satisfaction indicators for AFSC 426X2and 426X3 TAFMS groups are shown in Table 30. These are displayed alongside acomparative sample of similar career ladders surveyed in 1988. This gives arelative measr.re of how the job satisfaction of personnel in AFSC 426X2/X3compares with other similar Air Force career ladders. Additionally, jobsatisfaction indicators from the previous survey were examined to seek out anychanges in job satisfaction that may have occurred over time. These data arepresented in Tables 31 and 32 for each career ladder. Finally, job satisfac-tion across specialty jobs was reviewed to determine how overall job satisfac-tion may be influenced by the specific job performed.

Five attitude questions covering job interest, perceived utilization oftalents, perceived utilization of training, sense of accomplishment from thejob, and reenlistment intentions provide indications of job satisfaction.Both specialties had high positive responses for all the attitude questions(see Table 30). The majority of indicators had positive responses of 75-85percent in each career ladder. As shown in Table 30, this compares veryfavorably to a comparative sample of similar career ladders. These two pro-pulsion specialties had slightly higher job satisfaction indicators in allareas.

Comparing the 1982 job satisfaction data to the present data shows littlechange over time for AFSC 426X2 TAFMS groups (see Table 31). As Table 32shows, however, ther. is some noticeable change in AFSC 426X3 job satisfactiondata over time. Across all questions, job satisfaction indicators haveincreased in this specialty over the last 7 years. This was especially evi-dent in the first-and second-term groups.

Job satisfaction indicators for specialty jobs were also examined toidentify jobs having high or low job satisfaction (see Table 33). Most jobshad very high job satisfaction indicators, thus keeping in line with the over-all high career ladder indicators. A few jobs were identified, however, wheremany personnel indicated finding their job less than interesting. These jobs

IMPLICATIONS

As explained in the INTRODUCTION, this survey was requested to update thetasks performed in the career ladders since the previous OSR (1982); and toidentify what engine monitoring and engine management tasks are being done.Due to the recent Rivet Workforce initiatives, the two career ladders wereconverted into one ladder with two shreds. Since the survey was administeredunder the former AFSC designators, however, the findings have been reportedunder the prior classification scheme.

Comparing present and previous OSR data shows the specialty to be verystable in the jobs being performed. Three major technical jobs were identi-fied, in addition to a number of other smaller, more specialized jobs. Thisresulted in some diversity in the functional areas performed by propulsionpersonnel. Both AFSC 426X2 and 426X3 personnel exhibited enough similaritiesin their duties to be able tj identify jobs by functional area, as opposed toAFSC. This should not be interpreted as a recommendation to merge the twocareer ladders (or present shreds) since the two clear'y separated within theoverall jobs.

Though diversity was found in the jobs performed, examination of skilllevel progression shows 7-skill level qualified 'individuals performing many ofthe same tasks done by their wore junior counterparts. This implies thatwhile there is diversity in functional areas, the major repair and maintenancetype tasks are performed across the specialty. The biggest impact of thisdiversity in jobs is on the career ladder training documents; specifically,the STSs and POls. With so many varied functional areas employirg career lad-der members, several specific areas in the training documents were foundmatched to tasks performed by low percentages of career ladder groups. Strictinterpretation of appropriate regulations would call for many of low-performing areas to be removed from the training documents.

The publication of an OSR is an excellent opportunity to make an in-depthstudy of these areas in the training documents to ascertain their relevancefor cuntinued inclusion in the documents. Latitude is provided in AFR 8-13and ATCR 52-22 to have subject-matter experts examine these items and decidetheir fate. With proper justification and documentatior, many important areascould remain in the documents.
