B. Concurrent Requirements – None
C. Reason:
Eaton Aerospace has been made aware of several incidents where the actuator did not function as required during operation (i.e. un-commanded lowering). Upon further investigation, the cause was found to be excessive gear wear on the first-stage sun gear (output gear of the no-back assembly). Excessive wear of one 692D100-13 actuator may cause higher than designed loading on the remaining actuator. Preliminary investigation revealed that this condition is most likely to affect actuators exceeding 12,000 flight cycles on 767 aircraft. This condition presents a possible safety hazard and could result in a dispatch delay. By performing the actions described in this service bulletin, product reliability will be enhanced.
D. Description:
This Service Bulletin provides instructions in three sections. The first two sections provide instructions for re-identification of rotary actuators using a compliance plate and also remarking of the unit ID plate for the identified serial numbers listed in Table 1 herein. The third section provides instructions for disassembly, replacement of the ball detent matched set and 1st stage planetary gears and re-assembly of the rotary actuators. Upon completion of these actions, the rotary actuator shall be re-identified.
E. Compliance
Actions listed in this Service Bulletin should be accomplished at the earliest opportunity when manpower and facilities are available.
F. Approval:
The repairs and modifications herein comply with the applicable regulations and are on record with the supplier as FAA-approved, as well as EASA/JAA approved.
G. Manpower:
Estimated time requirements are as follows:
Accomplishment: (Para. 3. A., B. and C. - On-Aircraft Section) 1 hour (Approx.)
Accomplishment: (Para. 3. A. and D. - Off-Aircraft Section) 6 hours (Approx.)
