History : Triumph Air Repair

Triumph Air Repair - Phoenix was founded in 1977 known then as Tiernay Manufacturing and added repair and overhaul capabilities in 1978.  

We began overhauling environmental control units for Cobra Helicopters for the US Army. Our first APU was a Solar Titian Model T62-T39. Subsequently, the GTCP85 model as added which propelled our growth in both the commercial and military market segments.  

In the 1980’s our name changed to Tiernay Turbines with the development of Tiernay’s TT10 APU which were sold to the US military. In 1988 Alco Standard purchased the overhaul portion of the business and named it Triumph Air Repair and later became part of Triumph Group in 1993. 

With more than thirty years in the aviation maintenance repair and overhaul business, Triumph Air Repair has repaired over 8,000 APU’s and 200,000 accessories.  Triumph’s facility has production space in excess of 65,000 square feet and continues to add new APU product lines and services to support our customers. 

As an Authorized Honeywell Service Center, Triumph Air Repair became the Exclusive Factory Service Center for the GTCP 660 product line in October of 2000 and the TSCP700 in October of 2001.
