Boeing Model 767 Series Airplanes Powered by General Electric or Pratt & Whitney Engines
Superseded. A later AD replaced this one: AD 2004-09-14. Comply with the one in force.
Model 767 series airplanes, certificated in any category, as listed in Boeing Service Bulletin 767-54A0101, Revision 1, dated February 3, 2000.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes powered by General Electric or Pratt & Whitney engines, that requires repetitive inspections to detect discrepancies of the aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions, if necessary. This AD also provides an optional terminating action for the repetitive inspections. These actions are necessary to prevent fatigue cracking in primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine. This action is intended to address the identified unsafe condition.
