The C90A, introduced in 1984, incorporated an improved cowling design for more efficient air induction and reduced drag, an updated three-bus electrical system, hydraulically actuated landing gear, faired exhaust stacks, and Collins Pro Line avionics installed in a new instrument panel designed to reduce single-pilot workloads. A seven-seat version of the C90A was introduced in 1987, which featured an increase in maximum takeoff weight of 450 lbs., for a total MTOW of 10,100 lbs. In 1992, after a production run of 236 aircraft, the C90A was replaced by the C90B with its four-bladed propellers and significant improvements in cabin noise levels. The King Air C90A is powered by a pair of Pratt & Whitney Canada PT6A-21 turboprop engines flat-rated at 550shp each at ISA +18C. Engine inspection interval is 3,600 hours.
