Airworthiness Directives; McDonnell Douglas Model DC-10 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10 series airplanes, that currently requires inspection of the wing rear spar lower cap aft tang fastener and the wing trailing edge access door sill to detect fatigue cracking, and repair, if necessary. This amendment requires installation of a crack preventative modification of the wing rear spar lower cap, and follow-on inspections. This amendment is prompted by reports of additional cracking found in the current inspection area. The actions specified by this AD are intended to prevent propagation of cracks in the subject area, which could compromise the structural integrity of the airplane.
