Naval Aircraft Operating and Support Cost-Estimating Model - FY78 Revision.
Abstract
This report provides the updated equations using fiscal 1978 data for the Administrative Sciences Corporation Aircraft Operating and Support (O&S) Cost-Estimating Model. It is intended to be used as an addendum to Naval Aircraft Operating and Support Cost-Estimating Model - FY77 Revision, ASC-R-120, February 1979, which contains an extensive discussion of each cost element as well as other background material. Several initiatives to improve the quality and accuracy of the cost-estimating relationships were incorporated into this version of the model. The most notable is the examination of Replenishment Spares consumption over a two-year period rather than a single year. As more data becomes available, the period will be lengthened even more. Substantial work was also done in the areas of Engine Rework and Modifications. For engines, the recently implemented Engine Analytical Maintenance Plan which has changed the Navy's engine maintenance philosophy for most engines from one of scheduled overhaul to one without scheduled overhaul was investigated. This new policy provides for engine components to be replaced/overhauled periodically but not the entire engine. Although much useful data was obtained on engine removal rates and differentiation of maintenance costs for engines utilized in different aircraft (e.g., the J52-P8 in the A-4E and the A-6E); the data does not yet reflect the new maintenance policy.
