The '''Lycoming''' (now Honeywell) '''LTS101''' is a turboshaft engine family ranging from 650 to 850 shaft horsepower, used in a number of popular helicopters,<ref name="honeywell1">{{Cite web |url=https://aerospace.honeywell.com/products/engines/lts101 |title=Honeywell LTS101 |access-date=2015-11-24 |archive-url=https://web.archive.org/web/20160304095420/https://aerospace.honeywell.com/products/engines/lts101 |archive-date=2016-03-04 |url-status=dead }}</ref> and, as the '''LTP101''' turboprop, light aircraft. Both models carry the US military designation '''T702'''. The engine was originally designed at the Lycoming Turbine Engine Division in Stratford, Connecticut, but is now produced by Honeywell Aerospace.
