Airworthiness Directive · Amendment 39-12530 · McDonnell Douglas Model DC-9-10, -20, -30, and -40 Series Airplanes
McDonnell Douglas Model DC-9-10, -20, -30, and -40 Series Airplanes
Model DC-9-10, -20, -30, and -40 series airplanes, as listed in McDonnell Douglas Alert Service Bulletin DC9-33A037, Revision 02, dated July 27, 1999; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -20, -30, and - 40 series airplanes, that requires rework and reidentification of certain reflector assemblies of the passenger ceiling lights; and installation of a support channel above the reflector, as applicable. This amendment is prompted by reports of heat damaged lamp reflectors and scorched insulation blankets in the main cabin due to the lamps inside the reflectors creating high temperatures. The actions specified by this AD are intended to prevent overheating of the lamp reflectors, which could result in smoke and fire in the main cabin.
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.
