The Garrett AiResearch TPE-331 is a turboprop engine originally designed by AiResearch and now produced by Honeywell. It was designed to be both a turboshaft (TSE331) and a turboprop (TPE331), but the turboshaft version never went into production; however, over 14,000 TPE331s have been sold since the first engine was produced in 1963. The military version is the T76.
