Compliance is required within the next 50 hours' time in service after the effective date of this AD, unless already accomplished.

To detect spanwise cracks in the upper and lower wing main spar joint, accomplish the following:

  (a) Inspect the upper and lower wing main spar joints for cracks in accordance with the X-ray technique specified in Appendix I, Issue 2 as amended June 16, 1975, of Hawker Siddeley Technical News Sheet (T.N.S.) No. 134, Issue 5, dated March 17, 1975, or an FAA- approved equivalent.

  (b) If, during the inspection required by paragraph (a) of this AD, a crack is found in a wing main spar joint, before further flight modify the joint in accordance with Appendix 2 of Hawker Siddeley Technical News Sheet (T.N.S.) No. 134, Issue 5, dated March 17, 1975, or an FAA-approved equivalent.

This supersedes AD 57-05-02 that was contained in Supplement 2 to Part 507 of the Regulation of the Administrator (22 FR 6046) and that was transferred to Section 39.13 of the Federal Aviation Regulations upon the adoption of Part 39 (29 FR 14403).

NOTE: Copies of X-rays or of the results of the equivalent inspections as required by paragraph (a) of this AD are requested to be transmitted to DOT/FAA, Chief, Aircraft Certification Staff, Africa, and Middle East Region, c/o American Embassy, APO New York, N.Y. 09667.

(Reporting approved by the Bureau of the Budget under B.O.B. No. 04-R0174).
