BEECHCRAFT KING AIR 300 SERIES

Beechcraft King Air 300 for Sale — Buy or Sell King Air 300 and 350 Turboprops

The Beechcraft King Air 300 Series represents a significant performance leap in the King Air family — a high-altitude, high-speed twin turboprop that bridges the gap between the King Air 200 and purpose-built turboprop transports. Introduced in 1984, the King Air 300 combined the proven structural heritage of the Super King Air 200 with more powerful Pratt & Whitney Canada PT6A-60A engines, a redesigned pressurization system certified to 35,000 feet, and a stretched, restyled nose for additional avionics space and improved aerodynamics. The result was an aircraft capable of cruising at 310+ knots at Flight Level 350 — performance that challenged light jets and made the King Air 300 the preferred choice for demanding corporate operators who required turboprop economy with near-jet capability. On Airplane Trade, King Air 300 Series aircraft are listed for sale by qualified sellers for buyers who demand the finest in twin-turboprop business aviation.

Cabin and Interior

The King Air 300 Series cabin provides a genuinely premium business aviation environment. The stand-up cabin (57-inch headroom in the 350) accommodates passengers in club seating arrangements with generous legroom, individual reading lights and air vents, a forward galley, and an enclosed lavatory in most configurations. The stretched fuselage of the King Air 350 allows 10–11 passenger configurations in high-density arrangements while retaining full use of the rear baggage compartment — giving it a unique combination of range, speed, and group capacity unavailable in any comparable turboprop.

Avionics and Systems

King Air 300 Series aircraft have been equipped with a wide range of avionics configurations over their production run. Early aircraft feature conventional analog panels, while later 350s incorporate Rockwell Collins or Honeywell glass displays. Many aircraft have been retrofitted with Pro Line 21 glass cockpit upgrades, WAAS GPS navigation, ADS-B Out, and TCAS II. Buyers should assess the specific avionics fit of any aircraft under consideration, as panel configuration significantly affects workload, operational capability, and resale value.

Buying a King Air 300 Series: Evaluation Checklist

• PT6A-60A engine times — Engines approaching or beyond TBO (3,500 hours) represent a significant upcoming cost; verify last hot section inspection dates
• Pressurization system — FL350 certification requires a robust pressurization system; inspect for seal integrity, outflow valve condition, and controller function
• Maintenance program enrollment — Beechcraft MSP or JSSI enrollment confirms scheduled maintenance currency and provides cost predictability
• Avionics currency — Verify ADS-B Out compliance, GPS database subscriptions, and transponder certification
• Interior refurbishment history — Well-maintained interiors command premium valuations; assess leather, carpet, headliner, and cabinetry
