Stabilizer Trim Inoperative
Condition:
Both of these occur:
•Loss of electric trim through the autopilot
•Loss of electric trim through the control
wheel switches
Objective:
To land the airplane using manual trim or, if
manual trim is not available, to land the
airplane using the elevator control only.
Note: A maximum two-pilot effort on the trim
wheels will not cause a cable or system
failure.
The handle(s) should be folded inside the
stabilizer trim wheel when manual trim is no
longer needed.
If the failure could be due to ice
accumulation, descend to a warmer
temperature and attempt again.
