Airworthiness Directive · Amendment 39-10965 · McDonnell Douglas Model DC-10 Series Airplanes and KC-10A (Military) Airplanes
McDonnell Douglas Model DC-10 Series Airplanes and KC-10A (Military) Airplanes
Model DC-10 series airplanes and KC-10A (military) airplanes, as listed in McDonnell Douglas Alert Service Bulletin DC10-57A137, dated July 31, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10 series airplanes and KC-10A (military) airplanes, that requires repetitive inspections to detect cracking of the lower cap of the wing rear spar, and repair, if necessary. For certain airplanes, this AD also provides for an optional terminating modification for the repetitive inspections. This amendment is prompted by reports of fatigue cracks found in the lower cap of the wing rear spar. The actions specified by this AD are intended to detect and correct fatigue cracking of the lower cap of the wing rear spar, which could result in reduced structural integrity of the airplane.
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.
