REGULATORY TEXT:  
61-14-05 LOCKHEED: Amdt. 307 Part 507 Federal Register July 11, 1961. Applies to All Model 1049 Series Aircraft.

Compliance required as indicated.

As a result of numerous occurrences of loss of main landing gear doors, the following inspections and rework are required.

(a) Within the next 30 hours' time in service after the effective date of this AD and every 30 hours' time in service thereafter, conduct a visual inspection for cracks or loose fasteners in the front main landing gear door assemblies paying special attention to the front ribs and front hinge fittings. If any defects are found, they must be repaired or replaced prior to further flight, except that a ferry flight may be authorized in accordance with CAR 1.76 to a base where the required replacement or modifications are to be made.

(b) When doors incorporating the modifications outlined in Lockheed 1049 Service Bulletin No. 2935, or FAA approved equivalent, are installed, the special inspections described in (a) may be discontinued.

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

(Lockheed 1049 Service Bulletin No. 2935 pertains to this subject.)

This directive effective July 17, 1961.

Revised July 26, 1961.
