The PT6A engine family is the world's most popular engine in its class and is one of Pratt & Whitney's greatest success stories. Experience gained from the PT6A has helped spawn many of the engine families that have made Pratt & Whitney a world leader in the gas turbine engine market.
The versatility and proven performance of the PT6A makes it the engine of choice for demanding, high-cycle/high-power applications, in single- and twin-engine aircraft for missions and applications of all kinds. The PT6A is the only engine to achieve Single Engine Instrument Flight Rules (IFR) status for passenger revenue activity in North America, Australia, Europe and New Zealand.
Be more productive with your time. Ranging in power from 500 shp to over 1,900 shp, PT6A engines are available in more than 70 models, offering unsurpassed flexibility and capability for a variety of applications. The numbers speak for themselves: members of the family currently power aircraft in service with over 7,500 operators in more than 180 countries and having accumulated over 400+ million flying hours.
Customers are ready to fly when they need to with the digital solutions and information that keeps their engines working at their best. Operators of PT6A engines are supported by Pratt & Whitney-owned and designated service facilities around the world, field support representatives on six continents, a 24/7 Customer First Centre for rapid expert support, the most advanced diagnostic capabilities for this market, including the Know My PT6 app, and the largest pool of Pratt & Whitney rental and exchange engines in the industry. We are dedicated to keeping you ahead.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
