Airworthiness Directive · Amendment 39-12309 · McDonnell Douglas Model DC-9-10 and -30 Series Airplanes
McDonnell Douglas Model DC-9-10 and -30 Series Airplanes
Model DC-9-10 and -30 series airplanes, as listed in Boeing Alert Service Bulletin DC9-34A075, Revision 01, dated April 30, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10 and -30 series airplanes. This action requires replacement of a certain circuit breaker in the navigation transfer circuit located on the overhead circuit breaker panel with a certain new circuit breaker; and installation of a new nameplate. This action is necessary to prevent damage to wires or equipment and consequent smoke/fire in the cockpit from heat generated in the wires during an overload condition. 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.
