The airworthiness directive
75-08-13 MCDONNELL DOUGLAS: Amendment 39-2165. Applies to Model DC-10-10, DC-10-10F, DC-10-30, and DC-10-30F airplanes certificated in all categories.
Compliance required within the next 4000 flight hours after the effective date of this AD, unless already accomplished.
To minimize the possibility of losing a wing engine nose cowl due to severed nose cowl attach bolts and engine unbalance loads, modify the wing engine nose cowls per McDonnell Douglas DC-10 Service Bulletin 71-53, "Powerplant - Cowling - Modify Engine Nose Cowl Attachments," dated September 25, 1974, or later FAA-approved revisions, or an equivalent modification approved by the Chief, Aircraft Engineering Division, FAA Western Region.
Special flight permits may be issued under FAR 21.197 and 21.199 for the purpose of moving the aircraft to a base to perform the requirements of this AD.
This amendment becomes effective May 16, 1975.
