MINIMUM EQUIPMENT LIST.

CESSNA AIRCRAFT COMPANY MASTER MINIMUM EQUIPMENT LIST MODEL 525 OPERATIONAL AND MAINTENANCE PROCEDURES

NOTICE

The Master Minimum Equipment List (MMEL) is distributed by the Department of Transportation Federal Aviation Administration. This Master Minimum Equipment List Operation and

Maintenance Procedures Guide contains only the items from the Master Minimum Equipment List which have Operational (O) or Maintenance (M) procedure requirements. Cessna does not

support Minimum Equipment List items not published in the MMEL.

Cessna’s policy is to revise this guide only to accommodate changes to a new MMEL revision, which requires a change to, or a new, Operational (O) or Maintenance (M) required procedure. If

a revised MMEL is released, but does not affect any required procedure, the Operational and Maintenance (O&M) Guide will not be revised at that time. Cessna reserves the right to make

format changes without generating a new revision.

Operational (O) and Maintenance (M) procedures in this guide are recommended by Cessna Aircraft Company. Most of the procedures in this guide have been approved in some MEL’s. This document is not FAA approved, but is intended to aid operators in writing and gain approval for their specific Minimium Equipment List (MEL). It is not the intent of this guide to be used as part of any specific MEL. The Operator is responsible to ensure that all crew members are properly

trained in the use of MEL (O) and (M) procedures.

The Narrative section of each Maintenance (M) procedure is intended to satisfy the FAR 135 MEL requirement for training non-maintenance individuals whom are authorized, in the MEL, to

perform maintenance tasks.

MAINTENANCE PROCEDURES 1. Make appropriate entry on the discrepancy report. 2. Place placard on pedestal stating “ELECTRIC TRIM INOP”. 3. Disengage and secure the PITCH TRIM circuit breaker. 4. Check manual trim for freedom of movement throughout travel for

smooth operation. This will determine if there is any mechanical damage that would interfere with flight controls and preclude dispatch.

NOTE: If the electric trim is inoperative, it should be confirmed that

the problem is not in the manual (mechanical) trim system in the airplane and theat the failure is not affecting the manual trim. The manual trim should be run throughout its travel limits to check for binding and proper operation.

NOTE: Do not attempt to use the autopilot if electric trim is

inoperative. The autopilot will not be able to trim out servo torque, and disengaging the autopilot could result in significant pitch upset.
