About the Mitsubishi MU-2

The Mitsubishi MU-2 is a high-performance twin-turboprop business aircraft that stands out for its unconventional design choices and demanding flight characteristics. Built by Mitsubishi Heavy Industries from 1963 through 1986, the MU-2 was Japan's first postwar aircraft to achieve significant commercial success in Western markets, with over 700 produced across numerous variants. Unlike conventional light twins, the MU-2 uses full-span double-slotted flaps and spoilers for roll control instead of ailerons, a design borrowed from jet fighters that delivers exceptional short-field performance but requires precise pilot technique.

Powered by Garrett TPE331 turboprops producing 715 to 778 shaft horsepower each depending on variant, the MU-2 cruises at 300 knots and climbs rapidly to altitudes above 25,000 feet, performance that rivals much larger turboprops. Its high wing loading and relatively small control surfaces give it jet-like handling qualities that earned the type a reputation for being unforgiving of pilot error, leading the FAA to mandate special factory training for all MU-2 pilots under SFAR 108 in 2008. This regulatory intervention followed a period of elevated accident rates, though the aircraft itself is structurally sound and highly capable when flown within its envelope.

Today the MU-2 serves primarily in cargo, air ambulance, and corporate roles where its combination of speed, payload, and short-field capability remains valuable. The type's unique handling and training requirements have created a tight-knit community of operators who appreciate its performance once mastered. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
