Abstract : Mission profiles and maintenance procedures relating to the T56-A-14 turboprop engine were investigated to develop duty cycle information. This information was applied to a derivative engine designated as the 501-M71. A survey of fleet squadron pilots revealed that two profiles account for the majority of flight hours; anti-submarine warfare and pilot training. The T56 duty cycle was compared with the duty cycle for the 501-M71 derivative. The T56 uses twice as many cycles but less than one quarter of the hot time. This low hot time is attributed directly to the present T56 turbine temperature restriction. A new engine or derivative is likely to consume more hot time when operating without this restriction.
