History

By the time Beechcraft introduced the C90GT at Oshkosh AirVenture in 2005, the King Air C90A/B aircraft represented a 20-year long production run with very few changes. The King Air C90GT was introduced in 2006 as a direct response to the success of the Blackhawk engine conversion.

The new C90GT was the same as the C90B except it was equipped with the 750 SHP PT6A-135A engines derated down to 550 SHP takeoff power. The new engines increased cruising speeds at altitude by 24 knots to 272 KTAS. Approach-flaps takeoffs were introduced to the C90GTs for the first time, to compensate for the effects of reduced 1900 RPM of the -135A engines on takeoff.

This engine change increased performance due to lower operating temperatures, improving both cruise speed and climb rate. With a 275 kt (509 km/h, 316 mph) cruise speed, the C90GT was highly competitive with the new generation of Very Light Jets over short to medium distances, while providing a larger and more luxurious cabin. With deliveries beginning in early 2006, 97 C90GTs were delivered over a two year period.

On May 21, 2007, during the 7th Annual European Business Aviation Convention & Exhibition in Geneva, Beechcraft announced the Model C90GTi updated version of the C90GT, featuring the Rockwell Collins Proline 21 avionics package previously only offered for the B200 and B300 King Airs. The adoption of the Collins Proline 21 ‘glass cockpit' was the first major change to the avionics of the C90B/C90GT since 1992.

Deliveries commenced in 2008 and 125 C90GTis were added to the fleet, before being superseded by the new C90GTx in 2010.
