## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Lockheed Model L-1011- 385 series airplanes, that currently requires inspections to detect cracking of certain areas of the rear spar caps, web, skin, and certain fastener holes; and repair or modification, if necessary. That AD was prompted by reports of fatigue cracks in the caps of the wing rear spar inboard of inner wing station 346. The actions specified by that AD are intended to prevent rupture of the rear spar, which could result in extensive damage to the wing and fuel spillage. This action would add various improved inspections and follow-on actions, and would require that the initial inspections be accomplished at reduced thresholds.
