(2) If cracks exist, appropriate repair must be accomplished before further flight in accordance with Paragraph F of FAA approved Lockheed Service Bulletin 88/SB-669, or in a manner approved by the Chief, Aircraft Engineering Division, FAA Western Region.

(3) Report all results of this inspection whether accomplished before or after the effective date of this AD, to the Chief, Aircraft Engineering Division, FAA Western Region. Reports must include crack locations and length, if any, aircraft serial number, and accumulated hours' time in service. The data received in the required reports will form the basis for any further AD action that may be required. (Reporting approved by the bureau of the Budged under BOB No. 04-R0174.)

Airplanes with cracks may be flown in accordance with special flight permits issued pursuant to FAR 21.197 to a base where repair can be accomplished.

This amendment becomes effective on April 17, 1969.
