Abstract:

The purpose of the CH-54 Operational Statistics program was to validate the CH-54 helicopter in the Armys tactical aircraft reliability and maintainability model and to analyze the results obtained from the factorially designed arrangement of simulation runs on sensitivity, credibility, and sufficiency. Changes in utilization, failure rate, NORS waiting time, TBO concepts, major inspection durations, and repairreplacement time distributions were studied. Effects on operational availability, intrinsic availability, unscheduled elapsed maintenance downtime including and excluding NORS time, and mission accomplishment were evaluated. A baseline model was established by making successive simulation interations and refinements until all output statistics tested fell within the allowable statistical range of the expected CH-54B R and M characteristics and operational conditions.
