## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 767-200, -300, and -300F series airplanes. This proposal would require repetitive inspections of the aft pressure bulkhead web, and corrective action, if necessary. This action is necessary to detect and correct fatigue cracks in the aft pressure bulkhead web, which could result in uncontrolled rapid decompression. This action is intended to address the identified unsafe condition.
