The Dallas Airmotive and Pratt & Whitney Canada Partnership

Dallas Airmotive and its affiliate, H+S Aviation are OEM authorized on a broad range of Pratt & Whitney Canada engine platforms for both fixed and rotor wing applications since 1950.

In 1964, Dallas Airmotive was the first independent service organisation authorized to sell, distribute parts and service Pratt & Whitney Canada’s PT6A engine series. Today, both H+S Aviation and Dallas Airmotive are Designated Overhaul Facilities (DOF) for the family of PT6A engines. The companies offer a full range of support services from inspections through major overhaul. The world-class Airtight™ warranty, introduced in 1995, established the industry standard for overhauled engines. Our Airtight™ warranty covers all parts and labor for a period of 10 years or the manufacturer’s recommended TBO, whichever occurs first.

Dallas Airmotive provides 24/7 technical support of the PT6A engine series through our F1RST SUPPORT™ field service organisation and through strategically positioned Regional Turbine Centres (RTCs), where minor repairs, troubleshooting, power section and hot section inspections, FOD, Sudden Stoppage and Lightning Strike repairs can be performed. In addition, we also offer component and accessory repair, overhaul and exchange.

Contact us whenever you need assistance with your PT6A engine or contact us for more information.
