Airworthiness Directive · Amendment 39-12197 · McDonnell Douglas Model DC-8 Series Airplanes
McDonnell Douglas Model DC-8 Series Airplanes
Model DC-8 series airplanes, as listed in McDonnell Douglas Alert Service Bulletin DC8-24A068, Revision 01, dated November 1, 1999; certificated in any category; except those airplanes that have been converted from a passenger to a cargo- carrying ("freighter") configuration, without toilet flushing systems and associated equipment installed.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that requires replacing the toilet flushing circuit breakers of the lavatory with new circuit breakers, and marking applicable nameplates. This action is necessary to prevent overheating of the flush pump motor, which could result in damage to the flush pump motor cover, and consequent smoke in the lavatory area. This action is intended to address the identified unsafe condition.
