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, and -40 series airplanes, and Model KC- 10A (military) airplanes. This amendment requires inspection(s) to detect cracks of the attach bolts of the front spar support fitting of each wing, and replacement of attach bolts with ones that are corrosion-resistant. This amendment is prompted by a report of failure of the attach bolts of the front spar fitting as a result of corrosion pitting. The actions specified by this AD are intended to prevent such stress corrosion, which could lead to the failure of the attach bolts of the front spar; this situation could result in reduced structural integrity of the wing.
