MAXIMUM TIME POLICIES. SUMMARY EDITION.

Abstract

A cost-effective mathematical model to determine optimal (least long run cost) maximum allowable operating times for aircraft engines is described. The model uses actuarial failure rates to forecast future engine repairs under different maximum time policies and then determines the costs for each policy by using average costs per engine repair. All significant logistics costs associated with each repair action are included, such as estimates of average removal and reinstallation costs, costs of transporting engines to and from the repair facility, and repair costs. Costs are also used for the extra spare engines required to support given maximum time policies, for the penalty associated with aircraft downtime, and for the risks associated with unscheduled engine failures.
