SECTION 9 - SUPPLEMENTS
SUPPLEME NT 11 - FAA APPROVED
1. An autopilot or autotrim malfunction occurs when there is an
uncommanded deviation in the airplane flight path or when
there is abnormal control wheel or trim wheel motion . In some
cases, and especially for autopilot trim , there may be little to
no airplane motion, yet the red PITCH TRIM annunciator may
illuminate and an alert tone may sound.
The primary concern in reacting to an autopilot or autopilot
trim malfunction, or to an automatic disconnect of the
autopilot, is in maintaining control of the airplane. Immediately
grasp the control wheel and press and hold down the NP
DISCrrRIM INT switch throughout the recovery. Manipulate
the controls as required to safely maintain operation of the
airplane within all of its operating limitations. Elevator trim
shou ld be used manually as needed to relieve control forces.
Locate and pull the AUTOPILOT circuit breaker on the right
hand circuit breaker panel to completely disable the autopilot
system.
2. A manual electric trim malfunction may be recognized by the
illumination of a red PITCH TRIM annunciator accompanied
by an alert tone, or by unusual trim wheel motions with the
autopi lot mode OFF without pilot actuation of the manual
electric trim switches. As with an autopi lot malfunction, the
first concern following a manual electric trim malfunction is
regaining control of the airplane. Grasp the control wheel
firmly and press and hold down the NP DISCrrRIM INT
switch. Locate and pull the AUTOPILOT circu it breaker on the
right hand breaker panel.
3. Note that the emergency procedure for any malfunction is
essentially the same: immediately grasp the control wheel
and regain airplane control while pressing and holding the NP
DISCrrRIM INT switch down, and retrim the airplane as
needed. After these steps have been accomplished secure
the autopilot electric trim system by pulling the autopilot circuit
breaker. As with any other airpl ane emergency procedure, it
is important that the 4 steps of the AutopiloVElectric Trim
Emergency Procedures located on Page 13 of this supplement
are committed to memory.
