1. Electrical Load - REDUCE as follows:
a. LDG Light Switch - OFF (use as required for landing)
b. NAV Light Switch - OFF
c. STROBE Light Switch - OFF
d. AVN MASTER Switch – OFF
NOTE: Radio, Transponder, Pitch Trim, and options (MFD, Autopilot, and PS Intercom), if

2. Land as soon as practical.
ELECTRIC PITCH TRIM FAILURE
1. AVN MASTER Switch - VERIFY ON

•
If closed, pull (open) TRIM/AP Circuit Breaker, then reset (close) the circuit breaker.
è
Electric pitch trim system remains inoperative:
3. Reduce pitch control forces by changing speed or flap configuration (within airspeed limitations).
4. CRUISE - Consider range reduction and destination change if cruise speed is reduced by flap
speed limitations.
5. APPROACH - Establish stabilized approach using normal speeds is preferred. This may include
change of destination for longer runway.
6. LANDING WITH FAILED TRIM - Consider making Flaps UP landing if pitch control force
increases uncomfortably when lowering landing flaps.
7. Land as soon as practical.
è
Electric pitch trim system resumes normal operation:
8. Land as soon as practical.
