FGB IFM IVA 1—1 E 5 May 99

1. GENERAL INFORMATION

1.1. ACTIVITY AND OPERATION SEQUENCEDuring performance of any activities, the crew must:

1. Conduct all operations in accordance with the crew procedures or MCC instructions (relayed either byvoice via radio link or by radiogram).

2. Inspect working area.

3. Provide maximum comfort for operation in the working area.

4. Prepare all the tools and accessories and secure them in the working area.

5. Inspect all hardware (units, instruments, cables, assemblies, etc.), intended for installation, forabsence of any mechanical damage.

W A R N I N G

If any damage of paint coating, or housing of instruments,units, connectors, and cables, is detected, report to MCC.

6. Make sure all the systems, units or instruments intended for IFM activities have been previouslydeactivated/disabled.

7. Perform IFM operations and activities

8. Upon completion, check correctness of performed installation(s). 9. Log the time spent to perform activity. 10. Report completed activities to MCC.

W A R N I N G

Upon completion of IFM, proceed with re-activation ofinstruments, units and systems as well as their functionalcheckouts on MCC GO.

11. Carefully inspect working area.

12. Inventory tools and accessories and return them to their stowage locations.

13. Stow removed/replaced hardware in assigned stowage location(s). 14. On detection of deviations in operation of any of the systems, the crew needs to:

- record malfunction detection time;- describe the symptoms or character of malfunction;- prepare a report;- report to MCC during the next comm session.


15. During off-nominal situations (on condition their symptoms fully conform with those described in theflight procedures), the crew may, on its own accord, perform necessary actions in order to eliminateor localize the off-nominal situations, as prescribed by the flight procedures, and subsequentlyreport them to MCC during the next comm session.


1.2. SAFETY MEASURES

This document contains the procedures, designed to provide for crew safety and maintenance ofonboard systems. During performance of procedures, the crew must observe the followingrequirements: 1. All activities are conducted on MCC GO. 2. During translation and installation of units, do not let them strike any station structural elements. 3. During any IFM operations, all systems, units, and instruments, intended for such operations, shouldbe powered down. 4. When working with the systems, make sure to use only the equipment, accessories, protectionmeans, either specified by the flight procedures or recommended by MCC. 5. Do not allow any kinks of hoses or flexible air ducts. 6. Tighten all threaded connections smoothly and steadily. 7. When one crewmember is mating a connector, another crewmember should verify the connection.

W A R N I N G

Mating/demating of hot connectors is to be performed withextreme care and on MCC GO (i.e. during comm pass).

8. When demating hot connectors, quickly move cable end aside as soon as captive nut comes off thethreaded part of the connector shell.

9. When mating hot connectors:

% place cable network connector and respective connector on unit in alignment, after checking keypin alignment;

% if necessary, align connector key pins by rotating cable connector assembly ;% align cable connector so its captive nut is seated on the first thread of unit connector by advancing

it along its axis, avoiding any misalignment;% tighten captive nut by hand to the stop.

10. When mating HF connectors, do not rotate connector shell relative to cable. 11. When working with the hardware provided with protective plugs, caps, or covers (such as panels,

hoses, cables, etc.), ensure that:

% before operations & all protective tools are removed;% after operations & all protective tools are re-installed.

12. During cable installation, do not allow any kinks or twists of cable harnesses 13. All tools and equipment, used during IFM operations, should be properly secured.


14. In the event of an off-nominal situation (not described in the flight procedures), the crew should:

% halt operation of the failed system;% log detection time;% record symptoms or character;% prepare a report;% report to MCC during next comm session.
