    Applicability: Model 767 series aircraft, line numbers 1 through 230 inclusive.

                 Requirement: 1. Perform a one-time inspection of the tension bolts in the side load underwing fittings on both struts to determine whether tension bolts made of H-11 steel are installed, in accordance with Boeing Alert Service Bulletin (ASB) 767-57A0074, dated 17 May 2000, or Revision 1, dated 18 May 2000.

                 If the inspection shows conclusively that no H-11 steel bolt is installed, no further action is required by this Directive.

                 2. If any H-11 steel bolt is found during the Requirement 1 inspection, or if the type of bolt cannot be determined, before further flight, perform an ultrasonic inspection to detect cracking or fracturing of the tension bolts in the side load underwing fittings on both struts, in accordance with Boeing ASB 767-57A0074 or ASB 767-57A0074 Revision 1.

                 If any cracked or fractured bolt is found during any Requirement 2 inspection, before further flight, replace both tension bolts in the affected side load underwing fitting with new, improved bolts in accordance with Boeing ASB 767-57A0074 or ASB 767-57A0074 Revision 1.

                 If both tension bolts in one side load underwing fitting are found cracked or fractured during any Requirement 2 inspection, before further flight, perform inspections to detect discrepancies of adjacent structure in accordance with a method acceptable to the Authority.

               Note 1: Replacement of all H-11 steel tension bolts in the side load underwing fittings on both struts with new, improved bolts, in accordance with Boeing ASB 767- 57A0074, or Boeing ASB 767-57A0074 Revision 1, constitutes terminating action for this Directive.
