Development of the Beech Super King Air 200 began in October 1970. Essentially the 200 was similar to the 11 seat capacity King Air 100 but featured a number of significant modifications. Principal amongst these was the redesigned rear section incorporating a T tail design. Other changes included increased wing span (and therefore fuel load) along with PT6A-41 engines. The adaptability of the King Air 200 spawned a multitude of derivatives and provided the basis for the Beech 250, 300 and 350. Allaero's Beech King Air parts inventory includes avionics, oxygen and fuel systems components, instrumentation and wheels and brakes.
