Airworthiness Directive · Amendment 39-13287 · McDonnell Douglas Model MD-11 and MD-11F Airplanes
McDonnell Douglas Model MD-11 and MD-11F Airplanes
Model MD-11 and MD-11F airplanes, as listed in Boeing Alert Service Bulletin MD11-24A137, Revision 01, dated March 11, 2003; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and MD-11F airplanes, that requires a one-time visual inspection of the circuit breakers to determine if discrepant circuit breakers are installed, and corrective action if necessary. This action is necessary to prevent internal overheating and arcing of circuit breakers and airplane wiring due to long-term use and breakdown of internal components of the circuit breakers, which could result in smoke and fire in the flight compartment and main cabin. This action is intended to address the identified unsafe condition.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
