To detect internal corrosion of the engine mount stay strut, P/N 4 EM.357A and P/N 4 EM.359A, accomplish the following:
(a) Remove the stay struts from the aircraft and inspect in accordance with the X-ray procedure of Appendix 1 of Hawker Siddeley Technical News Sheet No. 229, dated March 19, 1973, or an FAA-approved equivalent.
(b) Replace any stay strut for which internal corrosion is detected by the inspection required by paragraph (a) of this AD with a new part or otherwise serviceable spare part of the same part number determined to be free of internal corrosion by the inspection required by paragraph (a) of this AD or an FAA-approved equivalent.
(c) It is requested that copies of the X-rays, or results of an FAA-approved equivalent inspection, be forwarded to the Chief, Aircraft Certification Staff, FAA, Europe, Africa, and Middle East Region, c/o American Embassy, APO New York, N.Y. 09667.
