Airworthiness Directive · Amendment 39-12205 · Boeing Model 767 Series Airplanes
Boeing Model 767 Series Airplanes
Superseded. A later AD replaced this one: AD 2003-18-10. Comply with the one in force.
Model 767-200 and -300 series airplanes having line numbers 1 through 669 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires revising the Airworthiness Limitations Section of the maintenance manual (767 Airworthiness Limitations Instructions (ALI)). The revision will incorporate into the ALI certain inspections and compliance times to detect fatigue cracking of principal structural elements (PSE). This amendment is prompted by analysis of data that identified specific initial inspection thresholds and repetitive inspection intervals for certain PSE's to be added to the ALI. The actions specified by this AD are intended to ensure that fatigue cracking of various PSE's is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
