This amendment supersedes an existing airworthiness directive (AD), applicable to McDonnell Douglas Model DC-9 series airplanes and C-9 (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, among other things, revision of the existing program to require visual inspections of additional structure. This amendment is prompted by new data submitted by the manufacturer indicating that certain revisions to the program are necessary in order to increase the confidence level of the statistical program to ensure timely detection of cracks in various airplane structures. The actions specified by this AD are intended to prevent fatigue cracking that could compromise the structural integrity of these airplanes.
