Airworthiness Directive · Amendment 39-9130 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company DC-9-87 (MD-87).
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), applicable to certain McDonnell Douglas Model DC-9-87 (MD-87) series airplanes. This action requires an inspection to detect chafing or arcing damage to the wiring of the aft right coatroom, the intercostal, and the recirculation duct assembly near longeron 5; and modification of the wiring installation for the aft right coatroom. This amendment is prompted by a report of an electrical fire that started due to a short in the coatroom wiring, which was caused by arcing and chafing damage to the wiring. The actions specified in this AD are intended to prevent severe damage to the airframe in the event of a fire caused by arcing and chafing damage to the coatroom wiring.
