McDonnell Douglas Model DC-9-81, -82, -83, and -87 Series Airplanes, and MD-88 Airplanes
Model DC-9-81, -82, -83, and -87 series airplanes, and MD-88 airplanes, as listed in Boeing Alert Service Bulletin MD80-23A100, Revision 02, dated February 8, 2001; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-81, -82, -83, and - 87 series airplanes, and MD-88 airplanes, that requires revising the wiring of the selective calling (SELCAL) system. The actions specified by this AD are intended to prevent inadvertent very high frequency transmissions and subsequent loss of radio communications for airplane and/or airport operations; and to prevent inadvertent high frequency transmissions and subsequent electrical shock to ground service personnel and/or damage to the airplane during fueling operations or fuel tank maintenance. 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.
