Airworthiness Directives; McDonnell Douglas Model DC-10 Series Airplanes and KC-10A (Military) Airplanes

概要

This amendment supersedes an existing airworthiness directive (AD), applicable to McDonnell Douglas Model DC-10 series airplanes and KC-10A (military) airplanes, that 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. This amendment requires clarification of some Principle Structural Elements (PSE) and some non-destructive inspection (NDI) procedures. This amendment is 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. The actions specified by this AD are intended to prevent fatigue cracking that could compromise the structural integrity of these airplanes.
