About

In 1998 Consolidated Heliflight was purchased by Northstar Aerospace. (a Canadian public company with operating subsidiaries in Canada and the United States) In 2002 the name was changed to Northstar Aerospace, Turbine Engine Service Group as the parent company integrated us into their organization. Northstar Aerospace, TESG rapidly developed a worldwide reputation as a premier PT6T and PT6A Overhaul and Repair Organization.

Northstar Aerospace, TESG continued to operate as an independent facility, providing a level of excellence in repairs, overhauls, and field service that was unequaled anywhere in the industry. “Many of our customers have been with us since the beginning and the majority of them are repeat customers to this day”. These results were achieved by directing all efforts and resources toward efficient, high-quality production and outstanding customer service.

In late 2008 Northstar Aerospace decided to divest itself of the Turbine Engine Services Group to concentrate on its core business of manufacturing and so began the bidding to sell the TESG asset.

In May of 2009 a successful bidder was declared, and the assets were transferred to M International. The former TESG was rebranded as Mint Turbines LLC, and officially began operations May 28th, 2009, as a newly Certificated FAA Part 145 Repair Station.

Mint Turbines LLC is continuing operations as an independent turbine engine maintenance, repair and overhaul facility located in Stroud, Oklahoma and building on the already excellent reputation of the former company. The repair station is authorized by the FAA for the repair and overhaul of the PT6A and PT6T turbine engines manufactured by Pratt & Whitney Canada, including the correlation of the PT6A test cell by P&WC. The facility has nearly 70,000 square feet of factory and warehouse space. Since 1981, many thousands of engines have been successfully repaired and overhauled at this facility.

In 2009 Mint Turbines LLC added the Maintenance, Repair, and Overhaul capability of the Honeywell, now Ozark Aeroworks as of 2023, T53 engine series (both military and commercial), as an OEM Certified Service Center, to its extensive product line, and have continued the PT6 standard of excellence including ISO 9001:2015 and AS9110C certification — one of only a handful of MRO facilities in North America.

The owners of Mint Turbines LLC are M International of McLean, VA, a privately owned export management and aviation parts supplier, and Sigma Federal of McLean, Va., a private equity firm. The principal owners of M International include; Richard McConn, Current President of the National Defense Industry Association (NDIA) and Founder & CEO of M International since 1979; Gary R.
