PT6A
More than an Engine
500 to 1,900 shaft horsepower class
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.
Overview
We are the #1 provider of engines and customer services solutions in the General Aviation segment. Our commitment to reliable innovation has led to multiple technological advances in the PT6A engine family. You can fly longer with our digital engine technologies to help you better plan your maintenance activities and reduce costs. You can count on our reliable customer service experts for real-time support no matter where you are in the world at any time of day.
Dependability and versatility
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.
Broad Power Range
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 7,100 operators in more than 180 countries and having accumulated over 400+ million flying hours.
Global Customer Support
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.
Features
The PT6A engine family continues to advance, incorporating the latest technologies in the drive to exceed our customers' expectations
The best of both worlds: Proven technology built upon a remarkable body of engineering achievement that has written new chapters in aviation history in collaboration with our partners, and disruptive technology that continues to make new aircraft applications possible.
Flexible engine architecture and modular reverse flow design simplify installation in both single- and twin-engine installations as well as tractor and pusher propeller configurations.
Simple, on-wing maintenance is possible for most tasks, where other engines might need a shop visit.
Easy access to all external components means there’s no other engine in General Aviation that’s easier to maintain than the PT6A.
The novel PT6A configuration has proven to be a key attribute to its success: its rearward, reverse flow inlet and forward facing turbine section providing fast maintenance turn-around through on-wing hot section refurbishment in most aircraft installations. The PT6A is a two-shaft engine with a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the propeller through an epicyclic concentric reduction gearbox.
