McDonnell Douglas Model DC-10-10, -30, and -40 Series Airplanes
Model DC-10-10, DC-10-30, and DC-10-40 series airplanes, certificated in any category; as listed in the following McDonnell Douglas service bulletins: McDonnell Douglas DC-10 Service Bulletin 57-78, Revision 1, dated August 26, 1986; McDonnell Douglas DC-10 Service Bulletin 57-79, Revision 1, dated September 21, 1979, as revised by McDonnell Douglas DC-10 Service Bulletin Change Notification 57-79, dated January 23, 1980; and McDonnell Douglas DC-10 Service Bulletin 57-82, dated February 19, 1980.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, -30, and -40 series airplanes, that requires replacement of certain taper-lok attachments and forward trunnion bolts with new components that attach the left and right main landing gear (MLG) to each wing. This amendment is prompted by a report indicating that, due to overstrength of the forward trunnion bolt, an MLG broke away and ruptured a wing fuel tank while an airplane was being operated off the runway. The actions specified by this AD are intended to ensure that the MLG separates from the wing when it is subjected to unpredictable overloads during abnormal operations, and to prevent consequent primary structural damage to 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.
