Beechcraft King Air C90GTx: Complete Specs, Performance, and Buyer's Guide (2026)
The Beechcraft King Air C90GTx, in production from 2010 (succeeding the C90GTi), is the smallest member of Beechcraft's iconic King Air twin-engine turboprop family - and the entry-level platform that has introduced thousands of operators to Beechcraft twin-turboprop ownership over the King Air 90 family's 60+ year history. The King Air 90 family began with the original Model 90 King Air in 1964 (based on the Model 65 Queen Air, featuring the then-new Pratt & Whitney Canada PT6A turboprop powerplants in place of Lycoming flat-six piston engines), making it the foundational variant of the King Air line and the longest continual production run of any civilian aircraft of its class (over 3,100 aircraft built across the entire King Air family since 1964 through current production). The Model C90GTx was the 2010 development - a direct evolution of the Model C90GTi with the addition of factory-standard winglets and full-fuel payload flexibility. Production of the C90GTx remains active, with a total of 168 aircraft built. Powered by twin Pratt & Whitney Canada PT6A-135A turboprop engines (each producing 550 shp), the C90GTx delivers 880-1,152 nautical miles of range, 274-280 knots cruise speed, 30,000 ft service ceiling, and 10,485 lb MTOW. The aircraft is single-pilot certified and accommodates 5 passengers (typical, plus pilot). The cabin features 12.5-12.6 ft length, 4.5 ft width, 4.9 ft (1.48 m) height, 48 cu ft baggage, and 227 cubic foot interior with more headroom and shoulder space than previous C90 models. 26 tuned vibration absorbers significantly reduce cabin noise. The cockpit panel features Collins Aerospace Pro Line Fusion avionics with simplified single-pilot operation, graphical touchscreen flight planning, high-resolution Synthetic Vision System, NextGen and precision GPS capabilities, integrated touchscreen checklists, and automatic wireless chart uploads. North America operates 42% of the C90GTx fleet, with South America at 32%, and Europe + Asia at 10% each. Pre-owned average price: $3.03M (per Aircraft Cost Calculator).
For operators wanting Beechcraft's entry-level twin-engine turboprop with single-pilot certification, the smallest King Air with the longest continuous production run of any civilian aircraft of its class, modern Pratt & Whitney Canada PT6A reliability, factory-standard winglets, and modern Collins Aerospace Pro Line Fusion avionics, the C90GTx represents the most accessible Beechcraft King Air ownership variant.

History as the King Air 90 Family Flagship
The King Air C90GTx represents Beechcraft's continued strategic refinement of the King Air 90 family - the foundational variant of the King Air line that established the platform's continuous 60+ year production run.
Platform timeline:
- 1964: Original Model 90 King Air enters production (based on Model 65 Queen Air, first with PT6A turboprop)
- 1964 onwards: Pressurized Model 90 developed (King Air 90)
- 1971: Stretched Model 100 King Air
- 1973: King Air B100
- 1974: Super King Air 200 (King Air 200) introduced
- 1990: King Air 350 (Model B300) introduced
- 2007: King Air C90GTi
- 2010: King Air C90GTx introduced (factory winglets + full-fuel payload flexibility)
