Reliability Assurance of Aircraft Structures

Part of the Sagamore Army Materials Research Conference Proceedings book series (SAMC, volume 24)


Airworthiness certification requirements recently adopted by the U. S. Air Force rely heavily on damage tolerance to assure in-service reliability of airframes. FAA requirements are currently undergoing revision, and will also depend on damage tolerance characteristics of airframe structures. Two major impacts of these developments are evident. First, designers and operators will pay more attention to fatigue crack propagation rates and progressive deterioration of residual static strength than heretofore, and secondly, inspection will be an integral and acknowledged feature of continued reliability in service.
