The Impact of Flight Operating Techniques Upon Engine Maintenance Costs 650212

When an airline finds itself in trouble with an engine because of high cost or poor reliability, or both, decisions frequently must be made long before a complete picture is available to the decision makers. Experience and judgment play a major role in selecting the course of corrective action. This paper reviews these difficult decisions in a specific case history. The results of those decisions are analyzed quantitatively and the significance of the results discussed qualitatively. A relationship is then drawn between the operators’ experiences and the design criteria established by the engine manufacturer in the design of new engines.
