Beechcraft Model 99. The Beechcraft Model 99 is a civilian aircraft produced by Beechcraft. It is also known as the Beech 99 Airliner and the Commuter 99. The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air. It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically designed nose structure.

Design and development
Designed in the 1960s as a replacement for the Beechcraft Model 18, it first flew in July 1966. It received type certification on May 2, 1968, and 62 aircraft were delivered by the end of the year.

In 1984, the Beechcraft 1900, a pressurized 19-passenger airplane, was introduced as the follow-on aircraft.

Production ended in early 1987 with 239 airframes completed. Nearly half the Beech 99s in airline service are now operated as freighters by Ameriflight.

Notable accidents and incidents
 In 1987, pilot Henry Dempsey survived an incident in which he was sucked out of the aircraft when he fell against a door in the hold which opened. He managed to hang on until the plane made an emergency landing and suffered only minor injuries.
 Bar Harbor Airlines Flight 1808 was a scheduled flight from Logan International Airport to Bangor International Airport in the United States on 25 August 1985. On final approach to Auburn/Lewiston Municipal Airport, the Bar Harbor Airlines Beechcraft Model 99 crashed short of the runway, killing all six passengers and two crew on board. Among the passengers was Samantha Smith, a thirteen-year-old American schoolgirl who had become famous as a "Goodwill ambassador" to the Soviet Union and had been cast on the television show Lime Street.
 Henson Airlines Flight 1517 crashed on September 23, 1985, when pilot errors led to a CFIT. 
 Holmström Air flight, a Beechcraft 99 crashed May 8, 1989 at Oskarshamn, Southern Sweden on final approach to Oskarshamn airport. The investigation found that the accident was probably caused by the pilot's inability to compensate for the rapid nose pitch-up that occurred when the wing flaps were deployed, engines running at high power and with the plane too aft-heavy. The plane pitched sharply up, stalled and fell to the ground. The crash and subsequent fire killed all 16 onboard including the two pilots. The passengers were made up of politicians and their aides working for the National telecom planning committee as well as two young students.
 A Beechcraft 99 operated by Wiggins Airways crashed immediately after takeoff from Manchester–Boston Regional Airport, New Hampshire, on January 26, 2024, amid stormy winter conditions.
