King Air 90
Beech has produced six different basic King Air models, with the 90 series the smallest. The first Model 90 King Air was introduced in 1964; it was basically a Queen Air with turboprops. After its introduction, the 90 series went through a number of airframe and powerplant modifications. The King Air competes with other turboprops such as the MU-2, Conquest, and Cheyenne 400 LS. Beech airplanes are now being built by Hawker Beechcraft Coorporation.
