The Beechcraft 99 is a twin engine, unpressurised turboprop that seats up to 17 passengers. It was designed in the 1960s as a replacement for the Beech 18 and derives from the earlier King Air and Queen Air; using the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both.
The 99 can seat a crew of two and up to 15 passengers. It is powered by two 550 hp Pratt & Whitney Canada PT6A-20 engines and first flew in July 1966. Type certification was granted on 2 May, 1968 and deliveries commenced later that year.
Subsequent models, the A99, A99A and B99, had differing powerplants, sub models and weights.
The 99A is powered by two Pratt & Whitney PT6A-27 engines, flat rated at 550 hp. The B99 is powered by two 680 hp Pratt & Whitney PT6A-27/28 engines driving three blade constant speed Hartzell propellers.
Production was halted in 1975 until 1979, when the aircraft returned in the form of the C99 Commuter, with Pratt & Whitney PT6A-36 engines flat rated at 715 hp. Deliveries of the C99 commenced following certification in July 1981, and production ceased in 1986.
