Cost of Operation - Utility/Offshore Oil Service

Variable Costs

The following information is supplied to aid in the preparation of cost estimates for the opera-

tion of the S-76C+ helicopter in utility/offshore oil service. Costs have been calculated in gener-

al accordance with the practices described in Guide for Presentation of Helicopter Operating

Cost Estimates, published by the Committee on Helicopter Operations Costs. This estimate

presumes a mature operation in which there has been opportunity for costs to stabilize and

assumes no benefit for warranties.

Direct operating costs are calculated for an S-76C+ flying 1,000 hours per year for 12 years

using 2001 component prices, average overhaul costs, and 2001 power-by-the-hour rates.

Unscheduled removals are based on historical fleet-wide data.
