McDonnell Douglas Model DC-9-10, -30, and -40 Series Airplanes and C-9 Airplanes
Superseded. A later AD replaced this one: AD 2002-13-12. Comply with the one in force.
Model DC-9-10, -30, and -40 series airplanes and C-9 airplanes, equipped with an attendants' work light in the aft cabin; certificated in any category; as listed in McDonnell Douglas Alert Service Bulletin DC9-33A058, Revision 02, dated January 27, 2000.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -30, and -40 series airplanes and C-9 airplanes, that requires an inspection to detect chafing of the wiring of the attendants' work light of the aft cabin, and repair of chafed wiring. This AD also requires modification and reidentification of the attendants' work light assemblies of the aft cabin. This action is necessary to prevent chafing of the ground wire against the positive contact of the lamp of the attendants' work light of the aft cabin, and consequent arcing or arcing damage to the wiring of the attendants' work light and transformer of the aft cabin. Such arcing or arcing damage could result in short circuits and consequent smoke and fire in the aft cabin area. This action is intended to address the identified unsafe condition.
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.
