Operation of the electric trim switch
system should occur only by movement of
pairs of switches. Any movement of the
elevator trim wheel while depressing only
one switch element denotes a trim system
malfunction. The AP/TRIM POWER switch
must be turned OFF and flight conducted
only by manual operation of the trim wheel.
(2) Pilot and copilot trim switches
Check individual element for no
movement of trim, then check proper
operation of both elements.

switches override copilot switches
while trimming in opposite directions,
commanded by pilot.

Never taxi with a flat tire or a flat shock
strut. During taxi operations, particular
attention should be given to propeller tip
clearance. Extreme caution is required
when operating on unimproved or irregular
surfaces or when high winds exist. If
operations produce a propeller RPM over
1600, retard propeller levers to the detent
to limit RPM to 1600 to help reduce the
possibility of ingestion of ground debris.
