The Beechcraft King Air is a twin-turboprop aircraft that is known for its versatility and reliability. The powerplant of the King Air is made up of two Pratt & Whitney Canada PT6A turboprop engines. These engines are known for their high power-to-weight ratio and low fuel consumption, making them a popular choice for regional and business aircraft.

The Engines

The PT6A engines in the King Air have a maximum power output of 850 horsepower each, allowing the aircraft to reach a maximum speed of approximately 300 miles per hour. They also have a high propulsive efficiency, which helps to reduce fuel consumption and increase the aircraft’s range. The engines are also equipped with a two-stage power turbine and a four-stage compressor, which allows for a smooth and efficient power delivery.

One of the key features of the PT6A engines is their ability to operate at high altitudes, making them well-suited for use in the King Air. The engines can maintain their maximum power output up to 25,000 feet, which is significantly higher than many other turboprop engines. This allows the King Air to operate at higher altitudes, providing better performance and a smoother ride for passengers.

The PT6A engines are also known for their durability and low maintenance costs. The engines have a TBO (time between overhauls) of 3,600 hours, which is significantly longer than many other turboprop engines. This means that the engines can operate for a longer period of time before needing to be overhauled, reducing downtime and maintenance costs for the aircraft.

In addition, Pratt & Whitney Canada offers a comprehensive maintenance program for the PT6A engines, which includes a variety of services such as engine overhauls, inspections, and parts replacement. The program also includes a variety of options for engine leasing, rental, and exchange, which can help to minimize the cost of ownership for operators of the King Air.


Overall, the Pratt & Whitney Canada PT6A engines are an excellent choice for the Beechcraft King Air. They provide the aircraft with high power, efficiency, and durability, while also reducing fuel consumption and maintenance costs. The engines’ ability to operate at high altitudes and Pratt & Whitney’s comprehensive maintenance program make the King Air a reliable and cost-effective option for regional and business travel.
