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.
