About the Beech Super King Air 350

The Beechcraft King Air 350 is the stretched, more powerful successor to the legendary King Air lineage that began in the 1960s, combining cabin-class comfort with rugged short-field performance. Introduced in 1990, the 350 features two Pratt & Whitney Canada PT6A-60A turboprops producing 1,050 shaft horsepower each, a fuselage nearly four feet longer than the 200-series, and seating for up to eleven passengers. It became the backbone of air ambulance fleets, corporate shuttles, and remote-area operations worldwide, particularly across Australia's outback, where its 1,800-nautical-mile range and ability to operate from unpaved strips make it indispensable for medical evacuations and charter work.

The type cruises at 310 knots true airspeed up to 35,000 feet, faster and higher than most piston twins while burning a fraction of the fuel of a light jet, and its PT6 engines are famous for reliability in harsh environments from the Australian desert to the Arctic tundra. Military variants serve as multi-engine trainers and light transports in several air forces, and the U.S. Army operates a specialized signals-intelligence version.

The 350's combination of speed, range, cabin volume, and operating economics has kept it in continuous production for over three decades, with more than 1,700 delivered. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
