History
The people behind Specialty Turbine Service have been active in the PT6/JT15D engine business since its inception more than 25 years ago. Recognizing that corporate operators needed specialized assistance during the expensive engine overhaul event, the company was formed in 1991. Since that time, STS has managed over 1000 engines through overhaul and repair events.
