Aging Evaluation Programs for Jet Transport Aircraft Structural Integrity

The paper deals with criteria and procedures in evaluation of timely preventive maintenance recommendations that will support continued safe operation of aging jet transports until their retirement from service. The active service life of commercial aircraft has increased in recent years as a result of low fuel cost, and increasing costs and delivery times for fleet replacement. Air transport industry consensus is that the older jet transports will continue in service despite anticipated substantional increases in required maintenance. Design concepts, supported by testing, have worked well due to the system that is used to ensure flying safety. Continuing structural integrity by inspection and overhaul recommendation above the level contained in maintenance and service bulletins is additional requirement, in such cases. Airplane structural safety depends on the performance of all participants in the system and the responsibility for safety cannot be delegated to a single participant. This system has three major participants: the manufacturers who design, build and support airplanes in service, the airlines who operate, inspect and maintain airplanes and the airworthiness authorities who establish rules and regulations, approve the design and promote airline maintenance performance.
