The cost of acquiring valid defense needs now and in the foreseeable future far exceeds available funds. To make sure that the limited funds are spent for requirements that are truly critical, the military services must have effectiveness procedures for determining this fact. One area in which computed requirements exceed available funds is the acquisition of spare aircraft engines which are routinely needed by the Air Force and the Navy to replace those engines that periodically undergo necessary maintenance or major overhaul.

Recommendation for Executive Action

  1. Status: Closed

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

    Recommendation: The Secretary of Defense should revise its Instruction 4230.4 to include cirteria to evaluate safety level needs in terms of their contribution to the operational status of the aircraft fleet the spares are to support. The Secretary of Defense should instruct the Air Force and the Navy to use engine removal rates which reflect a reasonable level of performance to be achieved at some future time when the engine matures and, in calculating requirements for the F-16 program, to consider the spare engines purchased for the F-15 and the number that will be available when the engine matures. The Secretary of Defense should have the Navy: consider aircraft carriers as overseas bases when computing engine requirements using currently published pipeline standards in order to differentiate overseas carrier operations and associated pipelines from shore bases and their limited operations in wartime; exclude support at the land bases for aircraft which will be deployed aboard aircraft carriers; and reduce the wartime flying hour rates by 10 percent for carrier based aircraft.
