Airworthiness Directive · Amendment 39-8806 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company MD-11, MD-11F.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires an inspection to detect chafing damage to certain wiring in the main avionics rack, repair or replacement of damaged wiring, and modification of the wiring installation. This amendment is prompted by a report of a chafed wire harness found on the main avionics rack on one airplane that resulted in arcing damage to the wire harness and adjacent structure. The actions specified in this AD are intended to prevent chafing of the main avionics rack wiring, which could result in arcing and a fire in the wire bundle; this could lead to damage to aircraft systems and loss of associated aircraft functions.
