## Summary

This document revises an earlier proposed airworthiness directive (AD), which would have superseded an existing AD that is applicable to McDonnell Douglas Model DC-10 series airplanes and KC-10A (military) airplanes. The existing AD currently requires the implementation of a program of structural inspections to detect and correct fatigue cracking in order to ensure the continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. The previously proposed action would have required, among other things, clarification of some Principle Structural Elements (PSE) and some non-destructive inspection (NDI) procedures. The previously proposed action was prompted by new data submitted by the manufacturer indicating that certain revisions to the program are necessary in order to clarify some PSE's and some NDI procedures. This action revises the proposed rule by deleting the requirement to perform visual inspections of Fleet Leader Operator Sampling (FLOS) PSE's. The actions specified by this proposed AD are intended to prevent fatigue cracking that could compromise the structural integrity of these airplanes.
