The Piper PA-31T Cheyenne is a turboprop development of the earlier PA-31P Pressurized Navajo.
Originally, the aircraft was an upgraded version of the Pressurized Navajo equipped with two Pratt & Whitney Canada PT6A-28 turboprop engines. Later, the aircraft was further refined and developed, including aerodynamic improvements and fuselage extensions. The PA-31T led to the development of the PA-42 Cheyenne III and IV.

The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since. The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, which had logged 400 million flight hours from 1963 to 2016. It is known for its reliability, with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A turboprop engine covers the power range between 580 and 1,940 shp, while the PT6B/C are turboshaft variants for helicopters.
The AEA Explorer is a large single-engine utility aircraft.
The Piper M-Class is a family of American light aircraft manufactured by Piper Aircraft of Vero Beach, Florida. The aircraft are powered by single engines and have six seats. Twentieth century production of the class was all piston engined, but turboprop versions called the M500, M600 and M700 (Fury) are now also available.
The Ayres Thrush, formerly the Snow S-2, Aero Commander Ag Commander, and Rockwell Thrush Commander, is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first example flew 68 years ago. Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered.
The Embraer EMB 121 Xingu is a twin-turboprop fixed-wing aircraft built by the Brazilian aircraft manufacturer, Embraer. The design is based on the EMB 110 Bandeirante, using its wing and engine design merged with an all-new fuselage. The EMB 121 first flew on 10 October 1976.
The Cessna 441 Conquest II is the first turboprop powered aircraft designed by Cessna and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8–9 passenger turbine development of the Cessna 404 Titan. The ICAO designator as used in flight plans is C441.

The Beechcraft Model 99 is a civilian aircraft produced by Beechcraft. It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air. It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically designed nose structure.
The Piper PA-42 Cheyenne is a turboprop aircraft built by Piper Aircraft. The PA-42 Cheyenne is a larger development of the earlier PA-31T Cheyennes I and II.
The Air Tractor AT-500 is a family of agricultural aircraft that first flew in the United States on 25 April 1986, manufactured by Air Tractor Inc. Of monoplane low-wing, taildragger configuration, they carry a chemical hopper between the engine firewall and the cockpit. Compared with their predecessor, the AT-500 family featured a wingspan increase of 50 ft, and an additional fuselage stretch of 22 in (56 cm), allowing for a larger chemical hopper. Almost all variants offer a widened "buddy" seat or a tandem seat for a passenger, observer, or loader; trainer aircraft with full dual controls have also been offered.
