CONCURRENT REQUIREMENTS None.
BACKGROUND Accomplishment of this service bulletin will make sure that any damage to the Thrust Reverser (T/R) Control System wire harnesses, T/R wire harnesses, and engine core compartment electrical harness is found and repaired. Damage to the wire harnesses can cause an uncommanded T/R deployment. If this service bulletin is not done, an in-flight T/R deployment can cause a loss of control and affect Continued Safe Flight and Landing (CSFL).
The Boeing Company has received a report of an MD-11 experiencing an uncommanded T/R deployment of the two transcowls on Engine 1 during takeoff at approximately 500 feet above ground level. In the Engine 1 pylon, damaged wiring was found, which could have caused or contributed to the deployment of the two transcowls.
This service bulletin gives the instructions to inspect, test, and repair the T/R Control System wire harnesses, T/R wire harnesses, and engine core compartment electrical harness. The inspections in this service bulletin will make sure any damage to the T/R Control System wire harnesses, T/R wire harnesses, and engine core compartment electrical harness is found and repaired before an uncommanded deployment of the T/R occurs.
