## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires a one-time inspection for missing bolts on the inboard and outboard support of the inboard main flap, and follow-on inspections and corrective actions, if necessary. For certain airplanes that are subject to the existing AD, this action would add requirements for a new one-time inspection for gaps, a new one-time torque check for loose bolts, corrective actions if necessary, and eventual replacement of existing titanium bolts with steel bolts. These actions are necessary to detect missing, loose, or cracked bolts on the supports of the inboard main flap and prevent loss of the inboard main flap, which could result in loss of control of the airplane. This action is intended to address the identified unsafe condition.
