McDonnell Douglas DC-9-51 and DC-9-83 Series Airplanes Modified by Supplemental Type Certificate SA8026NM
Model DC-9-51 and DC-9-83 series airplanes modified by Supplemental Type Certificate (STC) SA8026NM, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-9-51 and DC-9-83 series airplanes modified by Supplemental Type Certificate SA8026NM, that requires deactivation of the in-flight entertainment (IFE) system and removal of the system from the airplane. This action is necessary to prevent the inability of the flight crew to remove power from the IFE system when necessary. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. 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.
