Beechcraft Baron 55 – A55 (1961-1963)

Barons come in three basic types: the Baron 55 (short body), Baron 56 (short body) and Baron 58 (long body), with several sub-variants each.

The direct predecessor of the Baron was the Beechcraft 95 Travel Air, which incorporated the fuselage of the Bonanza and the tail control surfaces of the T-34 Mentor military trainer. To create the new airplane, the Travel Air's tail was replaced with that of the Beechcraft Debonair, the engine nacelles were streamlined, six-cylinder engines were added, and the aircraft's name was changed.

In 1960, the Piper Aztec was introduced, using two 250 hp Lycoming O-540 engines; Cessna too had improved their 310 with two Continental IO-470 D, producing 260 hp. Meanwhile, Beechcraft's Bonanza had been improved with a Continental IO-470-N, but the answer to competition was to make a true twin engined variant of the Bonanza.

The first model, the 55, was powered by two, six-cylinder IO-470-L engines, producing 260 hp at 2,625rpm; it was introduced in 1961. It included the fully swept vertical stabilizer of the Debonair, while still retaining the four to four+five place seating of the Travel Air.

After building 190 Barons that first year, Beech came out with the A55, which has a 10-inch longer fuselage and could be ordered with a second fold-down rear seat, bringing potential seating capacity to six (more on that later). A total of 309 A55s were built in 1962 and 1963.

The airplaneā€™s nose was then extended seven inches for more baggage and avionics equipment, and gross weight was bumped from 4880 to 5000 pounds. The airplane was redesignated B55. (per AvWeb site)
