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

3. Aircraft Attitude ............................................................ MAINTAIN / REGAIN AIRCRAFT CONTROL

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 and yaw
