REGULATORY TEXT:  
76-20-05 ARMSTRONG WHITWORTH: Amendment 39-2737. Applies to Model AW-650 Series 101 airplanes, certificated in all categories.

Compliance is required as indicated.

To prevent failure of main landing gear due to cracks in the main undercarriage auxiliary jack attach pin, accomplish the following:

(a) For airplanes with attach pins which have accumulated more than 6,000 landings but less than 10,000 landings on the effective date of this AD, within the next 50 hours time in service after the effective date of this AD, unless already accomplished within the last three calendar months, and thereafter at intervals not to exceed three calendar months from the last inspection, inspect the pin attaching the auxiliary jack to the drag stay for cracks, in accordance with Accomplishment Instructions 2A(1) through 2A(6) of Dowty Rotol Service Bulletin No. 32-50D, dated February 23, 1976, or an FAA-approved equivalent.

(b) If a crack is found as a result of any inspection required by this AD, before further flight, comply with paragraph (d) of this AD.

(c) For airplanes with attach pins which have accumulated 10,000 or more landings on the effective date of this AD, before further flight, except that the airplane may be flown in accordance with FAR 21.197 and 21.199 to a base for the performance of the work required by this AD, and for other airplanes before the accumulation of 10,000 landings on the attach pin, comply with paragraph (d) of this AD.

(d) Remove the pin attaching the auxiliary jack to the drag stay, install a new attach pin, Dowty Rotol P/N 100402604 in place thereof, and thereafter inspect in accordance with the repetitive inspection cycle set forth in paragraph (a) of this AD upon the accumulation of 6,000 landings on the new attach pin.

This amendment becomes effective October 14, 1976.
