This thesis is a study validating the cost effectiveness of the Component Improvement Program for aircraft engines. It determines the costs and benefits derived from the Navy incorporating Power Plant Change 111 which improved the interconnector harness end and mating thermocouple end connector of the T56-A-427 engine. Useful maintenance data pertaining to this component was extracted from the Naval Logistics Data Analysis (NALDA) system. Cost data pertaining to the Power Plant Change was taken from two sources, the Manufacturer's Engineering Program Description (EPD) and the Naval Air System Command's Configuration Change Control Board (CCCB) document. Based on the author's analysis, the improvement to the interconnector harness end and mating thermocouple end connector was cost-effective from both a financial break-even point in that the cost to produce the improvement will be recovered after three years, and from a Net Present Value analysis on this improvement which shows that the U.S. Navy will save more than $400,000 during the expected fifteen-year life cycle of the engine
