(b) For purposes of this AD, with the exception of cleats equivalent to those specified in the Service Bulletin, an FAA-approved equivalent may be approved by an FAA airworthiness or engineering and manufacturing inspector or the Chief, Aircraft Certification Staff, FAA, Europe, Africa, and Middle East Office. Any cleats equivalent to those specified in the Service Bulletin must be approved by the Chief, Aircraft Certification Staff, FAA Europe, Africa, and Middle East Office.

(c) Upon request of an operator, the Chief, Aircraft Certification Staff, FAA, Europe, Africa and Middle East Office, c/o American Embassy, Brussels, Belgium, may adjust the compliance time specified in paragraph (a) of this AD or approve a modification equivalent to that specified in the Service Bulletin provided such request is made through an FAA maintenance inspector and the request contains substantiating data to justify the request for that operator.

This amendment becomes effective July 14, 1980.
