## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires revising the Airworthiness Limitations Section of the Maintenance Planning Data (MPD) Document (767 Airworthiness Limitations Instructions (ALI)). The revision incorporates into the ALI certain inspections and compliance times to detect fatigue cracking of principal structural elements (PSE). This action would expand the applicability in the existing AD, and would require incorporating a new revision into the Airworthiness Limitations Section of the MPD Document. The actions specified by the proposed AD are intended to ensure that fatigue cracking of various PSEs is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes. This action is intended to address the identified unsafe condition.
