This peblication contains the fifty-two technical papers presented at the FAA-NASA Symposium on the Continued
Airworthiness of Aircraft Structures. The symposium, hosted by the FAA Center of Excellence for Computational Modeling of
Aircraft Structures at Georgia Institute of Technology, was held to disseminate information on recent developments in
advanced technologies to extend the life of high-time aircraft and design longer-life aircraft. Affiliations of the participants
iscluded 33% from government agencies and laboratories, 19% from academia, and 48% from industry; in all 240 people were
in atendance.
Technical papers were selected for presentation at the symposium, after a review of extended abstracts received by the
Organizing Committee from a general call for papers.

EXECUTIVE SUMMARY
The Federal Aviation Administration (FAA) and the National Aeronautics and Space
Administration (NASA) jointly sponsored the Symposium on Continued Airworthiness of
Aircraft Structures in Atlanta, Georgia, August 28-30, 1996. The Symposium was hosted by the
FAA Center of Excellence for Computational Modeling of Aircraft Structures at Georgia
Technical papers were selected for presentation at the symposium, after a review of extended
abstracts received by the Organizing Committee from a general call for papers. Keynote
addresses were given by Dr. George L. Donohue, Associate Administrator of Acquisition and
Research of the Federal Aviation Administration, and Dr. Robert W. Whitehead, Associate
Administrator for Research and Acquisition, National Aeronautics and Space Administration.
