tailieunhanh - Aging Aircraft - USAF Workload and Material Consumption Life Cycle Patterns

Throughout the 1990s and into this century, the United States Air Force (USAF) has found it necessary to retain its aircraft fleets for unprecedentedly long service lives. Current plans forecast keeping portions of some existing fleets for as long as 80 years of service. The safety, aircraft availability, and cost implications of that fleetretention policy are unknown.
