Preventive Maintenance Intervals for Components of the F-15/F100 Aircraft Engine.
Abstract
Costs of maintenance can be reduced for many engine components by replacement before failure. This has been one objective of the Air Force Reliability Centered Maintenance (RCM) program. The key to realizing cost savings is optimization of the replacement or inspection interval. Graphic solution techniques show promise as a simple, consistent, and valid method of interval determination. They are based on use of actual age-at-failure data and cost data for individual parts of an engine, such as fuel pump of rotor disc. This study illustrates a graphic method of determining their replacement intervals, using five components of the F100/F-15 aircraft engine as a case study. The resultant optimum intervals and expected costs differ up to fifty percent from methods where actual costs and actual ages-at-failure are not used. Graphic analysis is a quick method responsive to system changes, but depends on use of representative age-at-failure data. This study verifies a basic technique. Existing methods can be used to aggregate the set of intervals into an engine maintenance plan. (Author)
