D. Move the right stabilizer manual trim lever (or alternate electrical trim switch) on the control stand in both the airplane nose up and airplane nose down directions. Verify that the stabilizer does not move. If the stabilizer does move, an arm or control valve is failed in the energized position and dispatch is not allowed until repairs are made.
5. Remove electrical and hydraulic power.
6. If left or right stabilizer trim control module (M211, M212) is inoperative, placard the associated left or right autopilot channel - INOP.
NOTE: If the left or right stabilizer trim control module is found to be inoperative and the associated autopilot is placarded INOP, it is not necessary to perform the MAINTENANCE steps for an inoperative autopilot (DDG Item 22-10-1). The only operational consideration from 22-10- 1 is already mandated by proviso b) in 27-41-2.
OPERATIONS (O)
STAB TRIM Light may illuminate. If light illuminates, trimming using the control wheel switches will be reduced to half the normal rate. The MEL procedure confirms full trim rate is available from the alternate trim system prior to dispatch.
