Beechcraft King Air 90

The Beechcraft King Air 90 series, introduced by Beechcraft in 1964, marked the beginning of what would become the most successful line of twin‑engine turboprop aircraft in the world. Developed from the earlier Model 50, the King Air 90 combined a pressurized cabin with the reliability of the Pratt & Whitney PT6A engine, delivering superior performance for both civilian and military operators. Early variants such as the Model 65 and 90A featured a 2,000‑pound payload, a maximum cruise speed of 260 knots, and a range exceeding 1,200 nautical miles, while later upgrades added modern avionics, autopilot systems, and improved fuel efficiency. Its rugged undercarriage and short‑field capabilities made it popular for regional airlines, corporate transport, and medevac missions. The King Air 90 also served as the basis for a multitude of specialized versions, including surveillance, maritime patrol, and training aircraft, cementing its role as a versatile workhorse. Over six decades, more than 5,000 units have been built, influencing the design of subsequent King Air models and keeping Beechcraft at the forefront of turboprop innovation. Its lasting legacy continues to inspire new generations of pilots and engineers worldwide.
