AILERON AND AILERON TRIM CONTROL SYSTEM - ADJUSTMENT/TEST
1. Aileron and Aileron Trim Control System Adjustment
A. General
(1)
When installing new cables, the initial cable tension should be double the applicable values shown in Fig. 501. After the system has been cycled 20 times, the cable tension must be readjusted to correct values.
(2)
Some airplanes have on the aileron control wheels a foil marker calibrated in degrees of control wheel rotation. These foil markers are for flight crew use. Do not use these foil markers when adjusting or testing the aileron control system.
NOTE: Control wheel neutral position for maintenance purposes is determined by rotating the control wheel left and right in decreasing amounts until the neutral position can be determined by feel.
(3)
The aileron trim control system must be properly adjusted prior to checking or adjusting the aileron control system.
(4)
The aileron and aileron trim control systems are properly adjusted when the following results are obtained: (Refer to Fig. 501 for rigging pin locations and cable tension requirements.)
WARNING: ALL FLIGHT CONTROL SYSTEMS ARE FULLY POWERED. CHECK TO ENSURE THAT PERSONNEL AND OBSTRUCTIONS ARE CLEAR OF ALL CONTROL SURFACES BEFORE TURNING HYDRAULIC POWER ON.
(a) Aileron Trim Cables ATA and ATB
1) With the aileron trim control knob indicator in the zero trim position (Fig. 502), rigging pin A/S-13 shall fit without binding in aileron trim gearbox. Cable tension shall be within limits shown in Fig. 501. If discrepancies exist, adjust the cable turnbuckles in forward cargo compartment as described in par. C.(1).
