Analysis of F/A-18 engine maintenance costs using the Boeing Dependability Cost Model

Abstract

This thesis explores the use of a computerized aircraft maintenance system cost model to analyze the F/A-18 engine maintenance system. The Dependability Cost Model is a Paradox Data Base model, developed by the Boeing Corporation, and is currently used in the airline industry to estimate costs associated with maintaining aircraft or the implementation of service bulletin changes to the aircraft. Research was conducted to determine the feasibility of adapting this model to the F/A-18 using existing maintenance information systems, and the possibilty of forecasting future funding requirements driven by engine component service life changes. This research concluded that the Dependability Cost Model is a powerful management tool in the analysis of aircraft maintenance system costs. However, its use as a budget estimation tool in a rapidly changing cost environment presented a number of difficulties and yielded marginal results.
