The H+S Aviation and Light Helicopter Turbine Engine Company (LHTEC) Partnership

H+S Aviation as well as sister company, Dallas Airmotive, have been servicing Rolls-Royce engines since 1967 and Honeywell engines since 1998. Light Helicopter Turbine Engine Co. (LHTEC) is a joint partnership between these two leading original engine manufacturers, and due to the decades of successful support of Rolls-Royce and Honeywell engines, LHTEC chose H+S Aviation to assume sole responsibility for the aftermarket maintenance, repair, and overhaul of the CTS800 engine series in 2020.

With the CTS800’s modular nature of the engine, we can support operators by offering module repair and overhaul, component repair, in addition to the full-service engine repair and overhaul.

Contact H+S Aviation at any time when you’re in need of technical support for your CTS800 engine.
