REGULATORY TEXT:  
79-17-03 LOCKHEED-CALIFORNIA COMPANY: Amendment 39-3530. Applies to all L-1011-385-1, L-1011-385-1-14 and L-1011-385-1-15 series airplanes certificated in all categories.

To ensure the integrity of the main landing brakes input straps, accomplish the following:

(a) Within the next 200 hours' time in service from the effective date of this AD, unless already accomplished within the last 600 hours' time in service, perform a visual inspection of the four input straps P/N 1545026 (-129, -130, -131, -132) located in the forward electronics service center compartment. If any obvious structural deformations and/or cracks are found, replace the strap(s) prior to the next flight in accordance with the Lockheed-California Company Service Bulletin 093-32-153, Revision 1.

(b) Repeat the visual inspections and replacement of straps as necessary, of paragraph (a) above, at intervals of 800 hours' time in service, unless paragraph (c) below has already been accomplished.

(c) On or before December 31, 1979, install the new type design steel input straps P/N 1617522 (-101, -102, -103, -104) in accordance with the Lockheed-California Company Service Bulletin 093-32-153, Revision 1. This constitutes terminating action for the inspection requirements of paragraphs (a) and (b) of this AD.

(d) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections required by this AD.

(e) Alternative inspections, modifications or other actions which provide an equivalent level of safety may be used when approved by the Chief, Aircraft Engineering Division, FAA Western Region.

(f) Upon request of operator, an FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Engineering Division, FAA Western Region may adjust the initial and 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 that operator.

This amendment becomes effective September 24, 1979.
