Compliance required within the next 100 hours' time in service after the effective date of this AD, unless already accomplished within the last 20 hours' time in service, and thereafter at intervals not to exceed 120 hours' time in service from the last inspection.

(b) Inspect the main landing gear inboard door latch rollers and actuating mechanisms for improper action or binding.

(c) The repetitive inspections required by this AD may be discontinued when the modification described in Lockheed Service Bulletin 329-177 or 329-186, or an FAA-approved equivalent is accomplished.

(d) Upon request of an operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Southern 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.

This supersedes AD 64-19-05.

This directive effective September 25, 1965.
