The third C90 version, built 1984–1992 between the C90-1 and the quieter C90B.

The C90A delivers King Air toughness, two engines and the best support network in its class for roughly $0.7–1.5M. It is slower and shorter-legged than rival twins, so buy it for regional trips rather than long distances.

Buy it if

You fly two to four people 200–800 nm at a time, want two engines and a tall cabin, and value an airplane that almost any King Air shop in the country can maintain.

Skip it if

You regularly fly more than 800 nm with four aboard, need jet-like speed, or want a quiet cabin and modern glass cockpit without paying extra for upgrades.

Biggest compromise

Speed and reach. A stock C90A cruises at roughly 225–247 knots and carries only about 590 lb with full fuel, so four people and bags mean less fuel and roughly 835 nm of range.

Lineage

What came before and after

What changed from the King Air C90 / C90-1

  • Redesigned pitot-style engine cowlings from the F90-1 reduce drag and add cruise speed.
  • Hydraulic landing gear with a hand pump for emergency extension.
  • Improved electrical system plus the F90-1 pressurization and heating system.
  • Rudder boost added to ease handling if an engine fails.
  • Bonded wing spar caps with shear fittings instead of bolted fittings.
  • Later aircraft approved for 10,100 lb takeoff weight, up from 9,650 lb.

  • Beechcraft King Air C90B / C90SE instead: Same airframe with four-blade propellers and vibration absorbers for a much quieter cabin; costs more to buy.
  • Cessna Conquest I (425) instead: About 265 knots and longer range in a similar price bracket, with a lower cabin and different engines.
  • Beechcraft King Air E90 instead: The same cabin with 680 shp PT6A-28 engines for stronger climb; older, built 1972–1981.

Pratt & Whitney Canada offers flat-rate overhauls and hot-section credits for this engine; many owners have converted to PT6A-135A engines.

Known issues

  • Engine overhaul exposure

    Two PT6A-21 overhauls cost at least $638,000 at 2026 flat rates, so engine time largely sets the price.

  • Wing fitting inspection records

    Wing attach fittings need recurring inspections; an older King Air C90 broke up after a repair against factory guidance.

  • Lower weight on early aircraft

    The earliest C90As are limited to 9,650 lb takeoff weight, 450 lb less than later aircraft.

Pre-buy checklist

0 of 9 checked

Textron Aviation and a large network of independent King Air shops support the C90A, and Pratt & Whitney Canada's PT6 network handles the engines. Parts are widely available, though often expensive.

Review

The full review

Strengths

  • Tall cabin for its class at about 4 ft 9 in, with a four-seat club and an aft baggage area.
  • PT6A-21 engines with a 3,600-hour overhaul interval and the largest turboprop service network behind them.
  • Certified for one pilot and under 12,500 lb, so no type rating is needed to fly it.

Limitations

  • Slow for a twin at about 225–247 knots, 20–50 knots behind the Conquest I and MU-2 Marquise.
  • Only about 590 lb of payload with full fuel; four passengers means trading fuel for people.
  • A flat-rate engine overhaul costs $319,000 per engine in 2026, so engine time drives price.

The King Air C90A is the 1984–1992 version of Beechcraft's smallest King Air, the twin-engine turboprop line that has been in production in some form since 1964. Beechcraft built 235 of them. It sits between the C90-1 and the C90B, which kept the same airframe but added four-blade propellers and a quieter cabin. Compared with the C90-1, the C90A brought redesigned engine cowlings borrowed from the F90-1, hydraulic landing gear, an improved electrical system, a rudder boost to ease engine-out handling and a bonded wing spar. Later aircraft were approved for a 10,100 lb takeoff weight, up from 9,650 lb.

Pilot's take

The C90A feels like what it is: a stable, forgiving King Air that rewards smooth hands and careful planning. The rudder boost helps if an engine quits, but single-engine climb is modest at roughly 550–630 fpm, so takeoff planning matters on hot days and at high airports. Plan cruise in the low-to-mid 200-knot range and a fuel stop beyond about 800 nm with a full cabin. The hydraulic gear and straightforward systems are easy to learn, and the PT6s are tolerant if you watch temperatures on start. Most of what separates a good C90A from a tired one is in the logbooks, not the panel.

— TheJetGrade editorial

Who this is for

Owner-pilots stepping up from piston twins and small companies flying regional trips of 200–800 nm with two to five passengers, who value the King Air name, two engines and easy maintenance more than speed.
