About the Pratt & Whitney PT6A:

The Pratt & Whitney Canada PT6A is a family of twin-shaft turboprop engines and the world's most popular engine in its class. As many as 69 different versions of the PT6A have been produced - with engine power ranging from 500 to 2,000 shp. In service, PT6A-powered aircraft are used for many different purposes such as transport of people; (both private and commercial), dropping cargo in adverse weather conditions; military pilot training, surveillance and other special missions; and supporting various environmental efforts. The strength of the PT6A family is its dependability and versatility.

The PT6A is in service with both the U.S. Air Force (MC-12W) and the U.S. Army (C-12). The MC-12W and C-12 are military special mission aircraft and mainly provide intelligence, surveillance, and reconnaissance (ISR). The C-12 is powered by two PT6A-60A engines with 1,050 shp each.

Also, the PT6A is used on the T-6 Texan II military trainer aircraft, which provides undergraduate pilot training for the U.S. Air Force and U.S. Navy. The T-6 Texan II is powered by a single PT6A-68 engine with 1,100 shp.

The PT6A engine is one of the most popular and proven power plants in its class. Over the years, new aerodynamic technologies have enabled the PT6A engine to gain more power without significantly increasing its size or weight. Other innovations have reduced greenhouse gas emissions, increased maintenance intervals, and enhanced the ease-of-operation.

PT6A engines are currently in service with more than 6,500 aircraft operators in over 170 countries.

Since the PT6A family entered service in the 1960s, more than 41,000 engines have been produced. To date, the PT6A has accumulated 335 million flying hours and is therefore a highly proven and durable engine.
