TRAILING EDGE FLAP SYSTEM - MAINTENANCE PRACTICES
_________________________________________________
1. General
_______
A. There are two tasks in this procedure: There is one task for the deactivation and one task for the activation of the trailing edge flap system.
B. It is necessary to do the deactivation procedure for the trailing edge flap system before you do the work on the system. This is to prevent injury to persons and damage to equipment by the accidental operation of the trailing edge flaps. Make sure you put all equipment out of the limits of the travel of the trailing edge flaps.
C. The operation of the leading edge flaps and slats is related to the trailing edge flaps. Make sure to locate all equipment farther than the limits of travel of the leading edge flaps and slats.
D. To pressurize or depressurize hydraulic systems A and B refer to 29-15-00/201.
