Airworthiness Directive · Amendment 39-9039 · 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), applicable to certain McDonnell Douglas Model DC-10-10, -15, -30, and -40 series airplanes and KC-10A (military) airplanes, that requires inspections to detect fatigue-related cracking in certain areas of the horizontal stabilizer; and repair of cracked parts. It also requires installation of terminating modifications, which, when accomplished, would eliminate the repetitive inspections. This amendment is prompted by reports of fatigue-related cracks found on the horizontal stabilizer. The actions specified by this AD are intended to prevent loss of the load carrying and fail safe capability of the horizontal stabilizer, damage to the adjacent structure, and subsequent reduced structural integrity of the airplane, due to the problems associated with fatigue cracking.
