Airworthiness Directive · Amendment 39-9244 · McDonnell Douglas Model DC-10-10, -15, -30, -40, and KC-10 (Military) Series Airplanes
McDonnell Douglas Model DC-10-10, -15, -30, -40, and KC-10 (Military) Series Airplanes
Model DC-10-10, -15, -30, -40, and KC-10 (military) series airplanes; as listed in McDonnell Douglas Alert Service Bulletin A54-106, Revision 2, dated November 3, 1994; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas DC-10 and KC-10 series airplanes, that requires repetitive eddy current inspections to detect fatigue cracking of the pylon aft bulkhead flange, upper pylon box web, fitting radius, and adjacent tangent areas; and repair, if necessary. This amendment is prompted by fatigue cracking found in the wing pylon aft bulkheads on two airplanes. The actions specified by this AD are intended to prevent failure of the wing pylon aft bulkhead due to fatigue cracking, which could lead to separation of the engine and pylon from 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.
