The Mitsubishi MU-2 is a Japanese, high-wing, twin-engine turboprop aircraft with a pressurized cabin, manufactured by Mitsubishi Heavy Industries. It is known for its speed and short/rough-field performance. Production began in 1963 and ended in 1986, with 704 aircraft manufactured.
Development and Production
- Design work began in 1959, and the first prototype, MU-2A, underwent test flights in Japan.
- Production models were the MU-2B, with some upgrades leading to the MU-2B10 or "D" model.
- Production occurred in Japan and, for a period, in the United States (San Angelo, Texas).
- Two fuselage variants were produced: a short body and a long body, affecting seating capacity.
Key Features and Design
- Speed: The MU-2 was designed for speed, featuring a high-loaded wing with small wingspan.
- Short/Rough-Field Performance: Full-span Fowler flaps and massive landing gear contributed to rough-field capabilities.
- Roll Control: Uses spoilers instead of ailerons for roll control.
- Power: Initially Turbomeca Astazou, later Garrett TPE331 turboprops.
- Airframe: Robust and durable, with components like landing gear derived from jet aircraft.
Operational Performance
- Cruise Speed: Around 289 KTS (333 MPH).
- Range: Approximately 975 NM (1,122 SM).
- Altitude: Up to 31,000 feet.
Controversy and Reputation
Initially known for a high accident rate due to underprepared pilots, the MU-2 later proved to be a capable and safe aircraft when flown by trained pilots, supported by FAA-mandated training standards.
Variants
- MU-2A through MU-2N, with changes in fuselage length, pressurization, and powerplants.
- Military variants: LR-1 and MU-2S.
Display and Accidents
Displayed in Australia, Japan, Mexico, and the U.S. Notable accidents include George Mickelson and Perry Inhofe incidents.
