2011 Beechcraft King Air 350i

The Beechcraft King Air 350 is the flagship of the most successful turboprop family in aviation history — a pressurized, twin-engine aircraft powered by two Pratt and Whitney PT6A-60A engines (1,050 SHP each) that seats up to 11 passengers in a stand-up cabin and cruises at 312 KTAS with a range of 1,806 nm. Produced since 1990 with over 900 delivered, the King Air 350 is the aircraft of choice for corporate flight departments, air ambulance operators, government agencies, and special missions worldwide. Key variants. The King Air 350 (1990-2008): the original, with Rockwell Collins Pro Line II avionics. The King Air 350i (2009-2018): upgraded with Pro Line 21 avionics and improved interior. The King Air 350ER (extended range, additional fuel tanks). The King Air 360/360ER (2020-present): current production model with IS&S ThrustSense autothrottle, digital pressurization, and Innovative Solutions glass displays. The military C-12J and MC-12 Liberty are King Air 350 variants. Why the 350 is the benchmark. The King Air 350 operates from runways as short as 3,300 feet — accessing hundreds of airports that jets cannot use. The T-tail design and powerful PT6A-60A engines provide excellent hot-and-high performance. Cabin altitude of 10,000 feet at FL350 with 6.5 psi differential pressurization. The square-oval fuselage cross-section provides a true stand-up cabin with a flat floor. Buying advice. PT6A-60A engines are reliable but expensive — overhaul costs $400,000-$500,000 per engine. Verify engine program enrollment (Pratt and Whitney Eagle or MSP Gold). Propeller overhaul (four-blade Hartzell or McCauley) runs $35,000-$50,000 per side. Wing deice boot condition, pressurization system integrity, and avionics update status are key value drivers. The 350 landing gear uses a trailing-link design that provides excellent ride quality on rough runways but requires periodic inspection of the trunnion bearings. Market. King Air 350 (pre-2008): $1.5M-$3.5M. 350i: $3.5M-$6M. 360: $7M-$9M. A Beechcraft King Air 350 for sale is the ultimate turboprop — nothing else combines this cabin size, range, and runway versatility. Operating costs run $1,200-$1,800/hr all-in.
