This procedure applies only if the optional pitch trim servo is installed:
1. Indicates a failure of the pitch trim servo.
2. Control Wheel ............................................................................................................. GRIP FIRMLY
3. AP DISC / TRIM INT Button .......................................................................... PRESS and RELEASE
(Be prepared for high elevator control forces)
4. Elevator Trim .................................. AS REQUIRED USING ELEVATOR TRIM CONTROL WHEEL
NOTE
The autopilot may be re-engaged. Refer to the normal procedures section of this AFMS,
MANUAL PITCH TRIM WITH AUTOPILOT ENGAGED.
5. Yaw Damper ............................................................................................. ENGAGE AS REQUIRED
ESP ACTIVATION
1. Throttle ..................................................................................................................... AS REQUIRED
2. Aircraft Attitude ....................................................... MAINTAIN / REGAIN AIRCRAFT CONTROL
NOTE
If ESP is active for approximately 10 seconds, the autopilot will automatically engage in
LVL mode, an aural ‘ENGAGING AUTOPILOT’ will be played (or a Sonalert tone will
sound for installations without a supported audio panel), and the autopilot will roll the
wings level and fly at zero vertical speed. Refer to Section 7, System Description for
further information.
ESP will be disabled by pressing and holding the AP DISC / TRIM INT button. Releasing

1. Throttle ............................................................................................................................... REDUCE
2. Aircraft Attitude and Altitude ......................................................................................... MONITOR
After overspeed condition is corrected :
3. Autopilot .......................................RESELECT VERTICAL AND LATERAL MODES (if necessary)
4. Throttle ........................................................................................................... ADJUST as necessary
NOTE
Overspeed protection mode provides a pitch up command to decelerate the airplane to
or below the maximum autopilot operating speed.
