← Beechcraft King Air 90 family

The Beechcraft King Air C90 series is the entry point into the most successful turboprop family in aviation history. The C90 is a twin-engine, pressurized, six-to-eight seat turboprop powered by two Pratt and Whitney PT6A-21 engines (550 SHP each) that cruises at 215 KTAS with a range of 1,260 nm at FL270. Since the original King Air 90 was introduced in 1964, the C90 family has been the go-to aircraft for small corporate flight departments, charter operators, and owner-pilots stepping up from piston twins to turbine reliability. Over 2,000 King Air 90-series aircraft have been delivered.

Key variants. The C90 (1971-1982) established the platform. The C90A (1982-1992) improved the engine and systems. The C90B (1992-1994) added four-blade propellers and improved noise levels. The C90GT (2005-2008) upgraded to PT6A-135A engines (550 SHP) and Rockwell Collins Pro Line 21 avionics. The C90GTi (2008-2016) further refined the avionics. The C90GTx (2017-present) is the current production model with Innovative Solutions and Support (IS&S) glass cockpit displays and autothrottle.

Why the King Air C90. PT6A engine reliability is legendary — these engines routinely reach 8,000+ hours between overhauls on condition, with 99.95%+ dispatch reliability. Twin-engine safety, cabin pressurization to 4.0 psi differential (cabin altitude of 10,000 feet at FL220), and all-weather capability make the C90 a genuine step up from any piston aircraft. The King Air can operate from short and unimproved strips that jets cannot access. The global King Air support network is the largest for any turboprop.

Buying advice. PT6A engine condition is the primary value driver — verify hot section inspection (HSI) status, compressor turbine (CT) blade condition, and prop governor function. The C90 uses the smaller PT6A-21/135A (versus the -42/-52 in larger King Airs) — parts and overhaul costs are proportionally lower but still significant ($200,000-$350,000 per engine overhaul). Propeller overhaul (Hartzell or McCauley four-blade) runs $25,000-$40,000 per side. Check for spar strap compliance, wing deice boot condition, and pressurization system integrity.

Market. C90A: $400,000-$800,000. C90B: $600,000-$1.2M. C90GT: $1.2M-$2M. C90GTi/GTx: $2M-$3.5M. Beechcraft King Air C90 operating costs run $800-$1,200/hr all-in. A King Air C90 for sale is the most affordable way into turboprop twin ownership.

Buying a Used Beechcraft King Air C90GTx

Buying a Beechcraft King Air C90GTx centres on its turbine engine(s) — time to overhaul, hot-section history and any engine maintenance program — alongside airframe hours and cycles.

What to check before buying

  • Turbine engine status — hot-section and overhaul time, trend monitoring and whether the engine is on a maintenance program.
  • Airframe hours & cycles — high-utilisation turboprops accumulate cycles quickly; cycles can matter more than hours.
  • Equipment — cargo pod, floats/amphibian gear, de-ice and avionics all affect value.
  • Corrosion & logbooks — continuous records and a corrosion inspection, especially on float or marine-operated aircraft.
  • Pre-buy inspection — commission an independent pre-buy by a type-experienced shop.

Frequently Asked Questions — Beechcraft King Air C90GTx

What is the Beechcraft King Air C90GTx?
The C90GTx is the last and most refined member of the King Air 90-series — a light twin turboprop seating six to eight, with more powerful PT6A engines, winglets and an updated Pro Line Fusion flight deck, the final development of the C90 line.
What is the difference between the C90GT and C90GTx?
The C90GTx adds composite winglets and avionics updates over the C90GT, improving performance and modernising the flight deck, while keeping the same six-to-eight-seat 90-series cabin.
How much does a King Air C90GTx cost?
As the newest 90-series King Air, the C90GTx sits at the upper end of 90-series prices, varying with engine program, hours and avionics. See the live price range and median above.
What is the King Air C90GTx cruise speed and range?
The C90GTx cruises around 270 to 280 knots with a range near 1,250 nautical miles on its two Pratt & Whitney Canada PT6A turboprops; figures depend on weight and altitude.
How many seats does the King Air C90GTx have?
Six to eight in the cabin, plus two crew, depending on the interior configuration.
What is the difference between the King Air 90 and 200?
The 90-series, including the C90GTx, is the smaller, more affordable King Air; the 200 (Super King Air) is larger, faster, longer-range and seats more, with a T-tail.
Is the King Air C90GTx still in production?
The C90GTx was the final 90-series King Air; current King Air production focuses on the 260 and 360, so C90GTx aircraft are found on the used market.
