66-19-03 MARTIN: Amdt. 39-272 Part 39 Federal Register August 10, 1966. Applies to Model 404 Airplanes.

Compliance required as indicated.

To detect cracks in the main landing gear oleo cylinders, accomplish the following:

(a) Inspect main landing gear oleo cylinders, Martin P/N SE997712, in accordance with (c) within the next 50 hours' in service after the effective date of this AD, unless already accomplished within the last 100 hours' time in service, and at intervals not to exceed 150 hours' time in service from the last inspection.

(b) Inspect main landing gear oleo cylinders, except Martin P/N SE997712, in accordance with (c) within the next 50 hours' time in service after the effective date of this AD, unless already accomplished.

(c) Remove all grease, dirt, and loose paint in the area between the jury strut attach lugs of the right and left main landing gear oleo cylinders, and inspect each of these areas for cracks using an ultrasonic method or an FAA-approved equivalent method.

(d) If a crack is found during the inspection specified in (c), replace the cylinder with a part of the same part number inspected in accordance with this AD and found free of cracks or an equivalent approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, before further flight except that the airplane may be flown in accordance with FAR 21.197 to a base where the repair can be performed.

(e) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, may adjust the repetitive inspection intervals specified in (a) 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 directive effective August 19, 1966.
