Airworthiness Directive · Amendment 39-9121 · McDonnell Douglas Model DC-9 and DC-9- 80 Series Airplanes, Model MD-88 Airplanes, and Model C-9 (Military) Airplanes
McDonnell Douglas Model DC-9 and DC-9- 80 Series Airplanes, Model MD-88 Airplanes, and Model C-9 (Military) Airplanes
Model DC-9 series airplanes, Model DC-9-80 (MD- 80) series airplanes, Model MD-88 airplanes, and Model C-9 (military) airplanes; as listed in McDonnell Douglas DC-9 Service Bulletin 53-269, dated August 11, 1994; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to McDonnell Douglas Model DC-9 and DC-9-80 series airplanes, Model MD-88 airplanes, and Model C-9 (military) airplanes, that requires inspection of the tailcone release locking cable fitting assembly, and replacement or modification of the assembly, if necessary. This amendment is prompted by reports of the inability of the tailcone to deploy because the swaged ball on the cable had jammed after passing into the release handle hole. The actions specified by this AD are intended to prevent the inability of the tailcone to deploy, which could impede the egress of passengers from the airplane during an emergency evacuation.
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.
