Airworthiness Directive · Amendment 39-9397 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A, KDC-10), DC-10-40, DC-10-40F.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-10-10, -15, -30, -40, and KC-10 (military) series airplanes. This action requires inspections to detect cracking of the wing pylon aft bulkheads and upper spar webs, and replacement or repair, if necessary. This amendment is prompted by reports of fatigue cracking in the aft bulkhead and upper spar webs. The actions specified in this AD are intended to prevent failure of the wing pylon aft bulkhead due to fatigue cracking; such failure could lead to separation of the engine and pylon from the airplane.
