The Garrett AiResearch TPE331 is a turboprop engine originally designed and manufactured by Garrett AiResearch, and produced by Honeywell Aerospace since 1999 after AlliedSignal/Garrett acquired Honeywell, keeping the Honeywell name. The TPE331 family includes 18 models and 106 configurations; the engines range from 575 to 1650 shaft horsepower.[2][3][4] The military version is designated the T76.

Design and development

The TPE331 originated in 1961 as a gas turbine (the "331") to power helicopters.[5] It first went into production in 1963.[6] More than 700 had been shipped by the end of 1973.[7] It was designed to be both a turboshaft (TSE331) and a turboprop (TPE331), but the turboshaft version never went into production; the first engine was produced in 1963, installed on the Aero Commander in 1964 and put into production on the Aero Commander Turbo Commander in June 1965.[8] As of July 2016, more than 13,500 TPE331 engines have been delivered, logging more than 122 million hours of flight time.[1]
