Beechcraft King Air 300/350: US Fleet Statistics

The FAA aircraft registry lists 908 Beechcraft King Air 300/350 aircraft with a valid registration as of July 11, 2026. The Beechcraft King Air 300/350 is a multi-engine airplane, and this family groups every registered variant of the Beechcraft 300 together. It ranks #51 by registration count among the model families tracked in this dataset.

These counts come from the FAA MASTER file and reflect aircraft with an active “valid” registration status.

The median registered Beechcraft King Air 300/350 was manufactured in 2007. Most were built between 1988 and 2019, and manufacture years across the registered fleet span roughly 1984 to 2025. A manufacture year is on file for 749 of the 908 registered aircraft.

The FAA registry lists 908 Beechcraft King Air 300/350 aircraft with a valid US registration — about 6.5% of all turboprop-powered aircraft in the US crewed fleet, and #51 of the 75 model families tracked here. The registered fleet carries a median manufacture year of 2007, newer than the overall US general-aviation fleet, whose median airframe dates to 1979. By state, Texas, California, and Delaware together account for 28.3% of the fleet, and the top ten states hold 59.8%.

King Air 300/350 registrations track the corporate-aviation map, with Texas and California leading and Kansas — the type’s Wichita manufacturing home — again ranking high. Delaware’s large share reflects registration trusts and LLCs common to higher-value aircraft rather than where the airframes are based.

Of the three King Air families featured here, the 300/350 fleet is the newest by median manufacture year. A younger fleet typically means more airframes still on manufacturer-defined maintenance and inspection programs, where tracking factory intervals precisely — by date, hours, and landings — keeps warranty and support status intact.

Shares are computed from the FAA registry snapshot on July 11, 2026. Engine-type share is of all turboprop-powered aircraft in the crewed US fleet; state shares are of all 908 registered Beechcraft King Air 300/350 aircraft.

The Beechcraft King Air 300 and 350 are the largest and most capable members of the King Air twin-turboprop line. They pair turboprop operating characteristics and short-field access with a cabin approaching light-jet size, which makes the 350 in particular a natural step-up airframe for departments graduating from a 200.

Operators skew toward corporate flight departments, fractional and charter fleets, and special-mission roles such as surveillance and air ambulance. These aircraft are frequently dispatched on demand and flown two-crew, so the daily operational load is scheduling, crew assignment, and keeping maintenance status visible rather than the flying itself.

A healthy secondary market means many departments run mixed-age 300/350 fleets, combining recent airframes with older tails that carry longer maintenance histories.
