The Navy projected a backlog of depot level aircraft maintenance for the end of fiscal years 1976 and 1977 consisting mainly of airframes and repairable components. Essentially, the airframe requirement is not urgent. With improvements in the Navy's maintenance programs, some of which are in progress, this backlog is being reduced as the equipment is needed. The Air Force did not have a depot backlog.

Factors contributing to the difference between the Navy's and the Air Force's aircraft maintenance backlogs are: (1) the Navy schedules airframes into the depots more frequently than the Air Force; and (2) the Navy has not fully funded the depot level aircraft maintenance workload since 1970. The Navy's interval between depot visits is chosen relatively arbitrarily and has remained fairly static. The services' criteria for computing the backlog figures also differ.

Recommendation for Executive Action

  1. Status: Closed

    Comments: Please call 202/512-6100 for additional information.

    Recommendation: The Secretary of Defense should: require the Air Force and Navy to establish common criteria for determining when an aircraft should receive depot level maintenance; require that only aircraft actually in need of depot work be reported as an unfunded backlog requirement; require the Navy to resolve the problems contributing to the lengthy order-to-shipment times; and require the Air Force and Navy to eliminate, as much as possible, the differences in terms and acronyms used in their operational readiness reporting systems.
