Airworthiness Directives; McDonnell Douglas Model DC-8 Series Airplanes

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.
