Structural Reliability Assessment Methodology - Why Now

Abstract

Prior to the advent of the aging aircraft problem, the criterion for ensuring USN airframe safety was a damage index labeled FLE (Fatigue Life Expended). In retrospect, over several decades, the application of the FLE criterion has provided an exemplary, cost effective, structural-safety record. However, with today's realities, the structural engineering community is being directed to maintain airframes longer than originally envisioned and fly beyond the FLE criterion. Consequently, a reliability assessment will provide management with the needed technical support in order to make informed decisions regarding aging airframes and maintenance demands.
