THE SERVO POSITIONS WERE SET BY THE CENTERING SPRINGS THE LAST TIME HYDRAULIC POWER WAS SET TO OFF. NO TOLERANCES ARE SPECIFIED. ONLY USE THE DATA TO MAKE SURE THE SERVO IS ALMOST IN THE CENTER AND IS NOT AT THE POSITIVE OR NEGATIVE LIMIT.
IF THE NULL (RIG) VALUE IS NOT IN TOLERANCE, PRESSURIZE THE ELEVATOR FEEL PITOT SYSTEM TO 350 KNOTS (AMM 34-11-00/001). SET THE STABILIZER TRIM AT 6 UNITS SET THE STABILIZER TRIM AT 2 UNITS AIRPLANES WITH CONTROL WHEEL STEERING

 WARNING:_______ KEEP PERSONS AND EQUIPMENT AWAY FROM ALL CONTROL SURFACES WHEN
 HYDRAULIC POWER IS SUPPLIED.  AILERONS, ELEVATORS, RUDDER,
 FLAPS, SLATS, SPOILERS, ADN STABILIZER ARE FULLY POWERED
 SURFACES.  INJURY OR DAMAGE CAN OCCUR WHEN HYDRAULIC POWER IS

 SUPPLIED.

Do the "Supply Hydraulic Power" steps.

 S 742-284

 (3)
Do MCDP test 67.


 NOTE: The MCDP shows FCC # FAIL for a FCC that had a self-test
____ failure when it went into GRD TEST MODE. The MCDP shows FCC interface faults related to the aileron autopilot servos. The MCDP shows messages to make sure the hydraulic power is on, the aileron trim is set to zero, and that all three A/P channels are engaged in command mode. The MCDP then moves the aileron servo to the positive limit and shows the aileron surface position in degrees for each channel. The same is done for the negative limit. This does a test of the autopilot aileron servo limits. Refer to Fig. 202 for the limit parameters.

 NOTE: The MCDP shows FCC # FAIL for a FCC that had a self-test
____ failure when it went into GRD TEST MODE. The MCDP shows FCC interface faults related to elevator autopilot servos. The MCDP shows messages to make sure the hydraulic power is on, the stab aileron trim is set to 6 units, and that all three A/P channels are engaged in command. The MCDP then moves the elevator servo to the positive limit and shows the elevator surface position in degrees for each channel. The same is done for the negative limit. This does a test of the elevator autopilot servo limits. Refer to Fig. 202 for the limit parameters.
