Abstract : The technique currently used to forecast engine removals considers specific engine-aircraft combinations. If there is a significant difference in dependability of the same engine used in different aircraft it might be possible to redefine the engine-aircraft combination when forecasting and thus lower costs through a reduction or reallocation of the overall engine inventory. The F4 weapon system was selected as a study vehicle to analyze the effect of aircraft use or mission on engine dependability because the GE J79-15 engine is installed in different models of the F4 aircraft that are used for basically different purposes: reconnaissance and fighter-bomber missions. Engine failure data was obtained over an eight year period and statistically analyzed. (Modified author abstract)
