Airworthiness Directive · Amendment 39-10733 · McDonnell Douglas Model DC-9-80 Series Airplanes and Model MD-90-30 and MD-88 Airplanes
McDonnell Douglas Model DC-9-80 Series Airplanes and Model MD-90-30 and MD-88 Airplanes
All Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9- 83 (MD-83), and DC-9-87 (MD-87) series airplanes; and Model MD-88 and MD-90-30 airplanes; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-9-80 series airplanes and Model MD-90-30 and MD-88 airplanes, that requires a one-time inspection of the harness assembly of the tailcone emergency evacuation slide to determine the diameter of the swaged balls; reidentification of the harness assembly; and reinstallation or replacement of the assembly with a new assembly, if necessary. This amendment is prompted by a failed deployment of the tailcone emergency evacuation slide during a system test conducted by the manufacturer. The actions specified by this AD are intended to prevent failure of the tailcone emergency evacuation slide to deploy automatically due to incorrect diameter of the swaged balls on the wire rope of the harness assembly.
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.
