Airworthiness Directive · Amendment 39-12396 · McDonnell Douglas Model MD-11 Series Airplanes
McDonnell Douglas Model MD-11 Series Airplanes
Model MD-11 series airplanes, as listed in Boeing Alert Service Bulletin MD11-24A117, dated May 18, 2000; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires a one-time general visual inspection of the electrical wiring of the right side of the cockpit to determine if the electrical wiring is chafing against the observer station and to detect damaged wires; and corrective actions, if necessary. This action is necessary to prevent chafing and damage to electrical wires of the cockpit and consequent electrical arcing due to wires that were routed improperly during production of the airplane, which could result in fire and smoke in the airplane. This action is intended to address the identified unsafe condition.
