MAINTENANCE (M)
1. Verify the aileron trim system is centered as follows:
A. Observe the control wheels are essentially centered (within tolerance), i.e., the aileron trim indicator reads approximately zero.
NOTE: The MEL requirement to verify the trim system is centered is not intended to imply any particular tolerance. The intent is that the system is centered to the extent it is acceptable to the pilot. A tolerance of +/- one unit of trim is acceptable.
B. Pull and collar the associated circuit breaker.
C. If the control wheel is not centered, then install a dummy link to maintain a centered system.
2. Install a dummy link to center the aileron trim system as follows:
WARNING: DOOR LOCKS MUST BE PROPERLY INSTALLED PRIOR TO ACCESS TO LATERAL FEEL, CENTERING, AND TRIM MECHANISM. RAPID ACTION OF DOORS MAY INJURE PERSONNEL OR DAMAGE EQUIPMENT IF LOCKS ARE NOT PROPERLY INSTALLED.
A. Remove aileron trim actuator (AMM 27-11-14).
B. Cap and secure electrical connector.
C. Align rig pin holes A-1 and install rigging pin.
D. Install Aileron Trim Actuator Dummy Link part number A27088-13 or equivalent.
E. Remove rigging pin from rig pin holes A-1.
