Airworthiness Directive · Amendment 39-11136 · McDonnell Douglas Model MD-11 Series Airplanes
McDonnell Douglas Model MD-11 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-15-13. Comply with the one in force.
Model MD-11 series airplanes, manufacturer's fuselage numbers 0447 through 0464 inclusive, and 0466 through 0475 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires a one-time inspection to verify correct wire terminations of certain circuit breakers in the cockpit overhead switch panel; and correction of incorrect wire termination. This amendment also requires that operators submit a report of the inspection results to the FAA. This amendment is prompted by incidents in which the wiring of circuit breakers on the overhead switch panel lighting were found to be terminated improperly during production of the airplane, which bypassed the circuit breaker protection. The actions specified in this AD are intended to prevent smoke and possible fire in the overhead switch panel lighting circuitry due to an overload condition, as a result of lack of circuit breaker protection.
