Case Studies in Aircraft Structural Integrity

  • John W. Lincoln
Conference paper

Abstract

Fatigue failures in operational aircraft thirty-six years ago motivated the United States Air Force to establish the USAF Aircraft Structural Integrity Program (ASIP). Since that time there have been many technical challenges encountered in the course of acquiring new aircraft that have changed ASIP from its original formulation, but not its original purpose of maintaining structural integrity. It is the purpose of this paper to discuss the basic concept of the USAF Aircraft Structural Integrity Program and some of the challenges it has faced while maintaining aircraft safety and minimizing the cost of structural maintenance of in-service aircraft.
