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.
PWI's FAA-approved windows enhance ice detection on the leading edge of King Air and Beech 1900 wings. PWI has also added EDMO as distributor for its drop in replacement cockpit light LED upgrade systems.
PWI receives FAA PMA certification for LED ice light
December 16, 2021
Gaining PMA certification from the FAA means owners and pilots can now use PWI's brighter, cooler LED ice light as a drop in replacement. Its longer life means less cost and downtime from changing out bulbs.
The 303R LED reading light is designed to direct light at a 90° angle from the socket base. PWI says this newly approved and energy efficient equipment will be useful for backlit cabin signs as well as floor and cargo lighting.
