Airworthiness Directive · Amendment 39-11072 · McDonnell Douglas Model DC-10 and MD-11 Series Airplanes, and KC-10 (Military) Series Airplanes
McDonnell Douglas Model DC-10 and MD-11 Series Airplanes, and KC-10 (Military) Series Airplanes
Model DC-10 and MD-11 series airplanes, and KC-10 (military) series airplanes; as listed in McDonnell Douglas Service Bulletin DC10-32-248, dated December 17, 1997, and in McDonnell Douglas Service Bulletin MD11-32-074, dated December 15, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10 and MD-11 series airplanes, and KC-10 (military) series airplanes, that requires a one- time inspection for blockage of the lubrication holes on the forward trunnion spacer assembly, and a one-time inspection of the forward trunnion bolt on the left and right main landing gear (MLG) to detect discrepancies; and repair, if necessary. This amendment is prompted by reports of blockage by opposing bushings of the lubrication holes on the forward trunnion spacer assembly, and reports of flaking, galling, and corrosion of the forward trunnion bolt. The actions specified by this AD are intended to detect and correct such flaking, galling, and corrosion of the forward trunnion bolt, which could result in premature failure of the forward trunnion bolt and could lead to separation of the MLG from the wing during takeoff and landing.
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.
