Compliance required as indicated, unless already accomplished.

Because of recently discovered cracks in the stabilizer center section rear spar fitting, accomplish the following inspections and modification:

(a) Within 125 hours' time in service after May 2, 1964, for all affected aircraft except aircraft with Serial Numbers 17658 through 17690, and within 125 hours' time in service after the effective date of this amendment for aircraft with Serial Numbers 17658 through 17690, remove upper left-hand and right-hand rear stabilizer attach pins. Inspect pins and holes in fitting lugs for cracks, by magnetic particle or dye penetrant method. Clean up any corrosion on pins and lugs. Replace any cracked part before further flight. (Boeing Service Bulletin No. 1967 (R-1) covers this same subject.)

(b) Within 550 hours' time in service after May 2, 1964, for all affected aircraft except aircraft with Serial Numbers 17658 through 17690, and within 550 hours' time in service after the effective date of this amendment for aircraft with Serial Numbers 17658 through 17690, and at intervals not to exceed 1,650 hours' time in service from the last inspection, until (c) is accomplished, remove all stabilizer attach pins. Inspect pins and holes in fitting lugs for cracks, by magnetic particle or dye penetrant method. Clean up any corrosion on pins and lugs. Regrease pins with MIL-G-7118 grease and reinstall. Install cadmium plated pins only, unless chrome plating is required to build up pin diameter. Replace any cracked part before further flight. (Boeing Service Bulletin No. 1967 (R-1) covers this same subject.)

(c) Within 5,000 hours' time in service after the effective date of this AD, remove left- hand and right-hand stabilizers and ream the terminal fittings on the stabilizers and torque box. Install bushings in the reamed holes according to Boeing Service Bulletin No. 942 or an FAA approved equivalent. (Boeing Service Bulletin No. 942 covers this same subject.)
