METHODS OF ESTIMATING FIXED-WING AIRFRAME COSTS

This report documents revisions made to improve the cost estimating model developed and presented in R-547, Methods of Estimating Fixed-Wing Airframe Costs. 1 The revised cost model makes use of the same basic data utilized in the R-547 study. 2 However, several changes were made in developing input data from this basic information. Perhaps the most significant of these is the combining of the engineering and tooling values into a single variable. As a result of this aggregation, there are only three distinct cost elements in the revised model--(1) direct manufacturing labor, (2) manufacturing materials, and (3) engineering and tooling--instead of the four elements used in R-547. It was found necessary to combine tooling and engineering costs in order to separate recurring and nonrecurring costs for these two categories. This will be discussed more fully in the next section of this chapter. Additional adjustments to the input data were made to increase the usefulness of the model.
