Airworthiness Directive · Amendment 39-12800 · McDonnell Douglas Model DC-9-10, -30, -30F, and -40 Series Airplanes, and Model C-9 Airplanes
McDonnell Douglas Model DC-9-10, -30, -30F, and -40 Series Airplanes, and Model C-9 Airplanes
Model DC-9-10, -30, -30F, and -40 series airplanes, and Model C-9 airplanes; certificated in any category; as listed in McDonnell Douglas Alert Service Bulletin DC9-33A058, Revision 03, dated November 21, 2001; and equipped with an attendants' work light in the aft cabin.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -30, and - 40 series airplanes and Model C-9 airplanes, that currently requires an inspection to detect chafing of the wiring of the attendants' work light of the aft cabin, and repair of chafed wiring. That AD also requires modification and reidentification of the attendants' work light assemblies of the aft cabin. This amendment revises the applicability of the existing AD. The actions specified by this AD are intended 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. The actions of this AD are 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.
