## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to all Boeing Model 727 series airplanes, that would have superseded a previously issued AD that currently requires inspections to detect cracking of the actuator rib fitting of the inboard door of the main landing gear (MLG); and rework or replacement of any cracked fitting. The proposed action would have required inspections to detect cracking in an expanded area of the actuator rib fitting, and various follow-on actions. That action was prompted a report of a fractured rib fitting that had been reworked in accordance with the existing AD. This new proposed action would expand the area of inspection even further than what was previously proposed, and would supersede another AD that requires actions related to the addressed area of the MLG. The actions specified by the proposed AD are intended to prevent damage to the airplane caused by a failure of the landing gear to extend due to a fractured rib fitting.
