SECTION 3 – EMERGENCY PROCEDURES
Some emergency situations require immediate memorized corrective action. These steps are printed in bold
in the emergency procedures and should be accomplished without the aid of the checklist.
AUTOPILOT MALFUNCTION / PITCH TRIM RUNAWAY
If the airplane deviates unexpectedly from the planned flight path:
1. Control Wheel ............................................................................................................ GRIP FIRMLY
2. AP DISC / TRIM INT Button ............................................................................. PRESS AND HOLD
CAUTION
Be prepared for high elevator control forces.
3. Aircraft Attitude ....................................................... MAINTAIN / REGAIN AIRCRAFT CONTROL
4. Elevator Trim ........................................... RE-TRIM if necessary using Elevator Trim Control Wheel
5. Autopilot Circuit Breaker ........................................................................................................... PULL
NOTE
Do not release the AP DISC / TRIM INT Button until after pulling the autopilot Circuit
Breaker.
Pulling the autopilot circuit breaker will render the autopilot, yaw damper (if installed), and
ESP inoperative.
6. AP DISC / TRIM INT Button .............................................................................................. RELEASE
In flight, do not overpower the autopilot. The trim will operate in the direction opposing
the overpower force, which will result in large out-of-trim forces.
Do not attempt to re-engage the autopilot or use manual electric pitch trim until the cause
of the malfunction has been corrected.
