REGULATORY TEXT:  
64-02-03 CALLAIR: Amdt. 672 Part 507 Federal Register January 17, 1964. Applies to All Models A-5 and A-6 Aircraft.

Compliance required as indicated.

As a result of several failures of the front attaching tube of the horizontal stabilizer, accomplish the following:

(a) Within 25 hours' time in service after the effective date of this AD check for cracks as follows:

(1) Remove the horizontal stabilizers from the airplane and thoroughly clean the leading edge tube of the horizontal stabilizer by removing all paint, rust, and foreign materials. Check for cracks in the area where the tube attaches to the fuselage carry through member and also around the horizontal tail fixed handle area where the tube has been bent back to provide sweepback.

(2) Inspect for cracks using the magnetic particle inspection process.

(b) If cracks are found, either install a new stabilizer or make an FAA approved repair. Thereafter reinspect the stabilizer at intervals not to exceed 100 hours' time in service.

(c) If no cracks are found, reinstall stabilizers and reinspect at intervals not to exceed 100 hours' time in service.

(d) CallAir Service Kit No. 10 provides a suitable reinforcement of the empennage by the installation of additional brace wires to the forward portion of the tail surfaces. No further periodic inspections are required if CallAir Service Kit No. 10 is installed with a new or repaired horizontal stabilizer.

(CallAir Service Bulletin No. 10 covers this same subject.)

This directive effective January 17, 1964.
