Design and development

Designed in the 1960s as a replacement for the Beechcraft Model 18, its first flight was in July 1966. It received type certification on May 2, 1968, and sixty-two 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. Nearly half the Beech 99s in airline service are now operated as freighters by Ameriflight.

In July 2011 a total of 130 Beech 99 aircraft remained in civil service, all but two of them in North and South America. Major operators included Alpine Air Express (12 aircraft), Ameriflight (57), Bemidji Airlines (11), and Wiggins Airways (10) with these aircraft primarily being operated in air freight operations. 22 other airlines and the National Police of Colombia operated smaller numbers of the type.Wiggins was acquired by Ameriflight and is the biggest operator of the type.[1] In June 2015, Lake Clark Air was operating a Beech 99 from Port Alsworth, AK.[2]



Former airline operators in the U.S. and Canada

A considerable number of commuter and regional airlines in the U.S. previously operated the Beechcraft Model 99 in scheduled passenger service. The following list of air carriers is taken from Official Airline Guide (OAG) flight schedules from 1974 to 1995:[3]

Other small commuter airlines in the U.S. and Canada operated the Beechcraft Model 99 as well. The aircraft has also been used in air cargo feeder operations transporting freight.

In addition, Texas International Airlines, which operated Douglas DC-9-10 and McDonnell Douglas DC-9-30 jetliners as well as Convair 600 turboprops, also flew several Beechcraft 99A aircraft during the early 1970s.[4]
