Compliance required as indicated.
As a result of landing gear cross tube end fitting failures, the following is required:
(a) (1) End fittings which have accumulated 11,000 or more landings as of the effective date of this AD, shall be inspected in accordance with (b) within the next 500 landings, and thereafter within each 3,000 landings.
(2) End fittings which have accumulated between 10,000 and 11,000 landings as of the effective date of this AD shall be inspected in accordance with (b) within the next 1,000 landings, or upon the accumulation of 11,500 landings, whichever occurs first, and thereafter within each 3,000 landings.
(3) End fittings which have accumulated less than 10,000 landings as of the effective date of this AD shall be inspected in accordance with (b) upon the accumulation of 11,500 landings and within each 3,000 landings thereafter.
NOTE: It will be necessary for operators to maintain a record of landings in order to ascertain compliance with this AD. If past records are unavailable, the number of landings prior to this AD may be estimated.
(b) Inspect the fittings listed below for cracks in accordance with PTL 234 (for Models 744 and 745D) or PTL 100 (for Model 810) or FAA-approved equivalent.
Model 744 & 745D - Fitting: End fitting for single piece tube, Station 96 - P/N 72450-35
Model 744 & 745D - Fitting: End fitting for single piece tube, Station 131 - P/N 72450- 37 or 72450-175
Model 810 - Fitting: End fitting for single piece tube, Station 96 - P/N 72450-35
Model 810 - End fitting for single piece tube, Station 131, P/N 81050-35
(c) Fittings with cracks in the 1/4-inch radius between the bearing journal and the tapered portion shall be replaced prior to further flight, except that those at Station 131 may be reused if they meet thelimitations of the applicable PTL Issue 5 dated June 1, 1965, and are reworked as specified in the applicable PTL. (Fittings at Station 96 are of different design and cannot be reused should similar defects be found.)
(d) Rework fittings having minor surface cracks in the attachment flanges and in the bearing journals in accordance with the provisions of the PTL's.
(e) Mark all reworked fittings with the letter "R" on the flange circumference.
(f) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Certification Staff, European Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator.
