Airworthiness Directive 2010-14-18
recurringAirworthiness Directives; The Boeing Company Model 767-200, -300, and -300F Series Airplanes Powered by General Electric or Pratt & Whitney Engines
What this AD requires
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, and -300F series airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the 8 aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. The existing AD also requires repetitive inspections for cracks of the closeout angle that covers the 2 aft-most fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. The existing AD also provides an optional terminating action for the repetitive inspections. This new AD reduces the compliance times for doing the inspections. This AD results from reports of cracks in the midspar fitting tangs. We are issuing this AD to detect and correct fatigue cracking in the primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine.
Which aircraft AD 2010-14-18 applies to
Applies to airplanes certificated in any category, as identified in Boeing Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010 (strut midspar fitting tang cracking).
Whether AD 2010-14-18 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
