Beechcraft Model 99
From Wikipedia, the free encyclopedia
The Beechcraft Model 99 is a civilian aircraft produced by the Beech Aircraft Corporation (previously the Beechcraft Division of Raytheon and now a unit of Hawker Beechcraft). It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engined, unpressurized, 17-seat/15 passenger turboprop aircraft, derived from earlier Beechcraft King Air and Queen Air, using the wings of the Queen Air, and the engines and nacelles of the King Air, and sub-systems from both, and with a unique nose structure used only on the 99.
