Boeing Model 767 Series Airplanes Powered by General Electric or Pratt & Whitney Engines
Superseded. A later AD replaced this one: AD 2005-19-23. Comply with the one in force.
Model 767 series airplanes, as listed in Boeing Service Bulletin 767-54A0101, Revision 3, dated September 5, 2002; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes powered by General Electric or Pratt & Whitney engines, that currently requires repetitive inspections to detect discrepancies of the four aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions, if necessary. That AD also provides an optional terminating action for repetitive inspections. This amendment expands the area on which the inspections are required. The actions specified by this AD are intended to prevent fatigue cracking in the 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.
