History
In 1966, after 112 65-90s were completed, production switched to the Model 65-A90 with PT6A-20 engines. As a measure of the type's popularity, 206 65-A90s were built in less than two years when production switched to the Model B90, the first of these rolling off the production line in 1968.
The King Air B90 came with a 350 lb gross weight increase, improved ailerons, increased wing span, recontoured rear fuselage, improved instrumentation with balanced controls, pressurization and had an extra side window.
A total of 184 B90 models were produced before the Model C90 was introduced in 1971, with wingspan increased over earlier models by 4 ft 11 in (1.50 m) to 50 ft 3 in (15.32 m), Maximum Take-Off Weight (MTOW) increased by 350 lb (160 kg) to 9,650 lb (4,378 kg), and PT6A-20A engines.
