Summary:

The military services have neither completed nor updated their reliability-centered maintenance analyses on operational aircraft and aircraft engines. Such analyses, part of an overall preventive maintenance approach, are intended to restore equipment to its design levels of safety and reliability. The goal is to ensure, at the least expense, that equipment lasts as long as it was designed to. Service officials said that performing or updating analyses of operational equipment with extensive maintenance experience was not cost-effective. The services are, however, doing reliability-centered maintenance analyses of major systems under development, such as the Army's T800 engine and the Air Force's F-22 aircraft. Pentagon officials believe that applying concepts such as reliability-centered maintenance during system development contributes to efficient preventive maintenance programs.
