The Air Force's computation of replenishment spares requirements ignores the existence of spare engines and the need for them. This overstates the contribution of engine components to aircraft availability rates and distorts the predicted availability resulting from a given investment in spares. This report documents a study of two engines, using the LMI Aircraft Availability Model, which shows that these errors can be significant. The magnitude and direction of the error depends on the balance between requirements for whole engines and the existing spares levels. In addition to quantifying the effects of engines, this report suggests specific ways in which engines can be included in the availability-based techniques now being introduced into the Air Force's computation.
