History

The Model 55 was Beech’s first Baron. It came out in 1961 as a replacement for the Model 95 Travel Air, which was a bit long in the tooth to meet competition from Cessna’s 310 and Piper’s Aztec.

Like the Travel Air, the 55 comprised a Bonanza fuselage fitted with a conventional tail, not the V-tail. In place of the Travel Air’s somewhat anemic 180-HP Lycomings, the original Baron had 260-HP Continental IO-470L engines.

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 airplane’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.

The B55 was fitted with 260 hp (194 kW) Continental IO-470 engines and had a gross weight of 5100 lb (2,300 kg). It had a typical cruise speed of 196 knots at 7000 ft, and came with 136 US gallon (useable) fuel tanks.

This version remained in production the longest, until 1983, when all 55s were dropped from the line, along with the 58TC and V-tail Bonanza. Browsing the for-sale ads, expect to see more B55s than any other model because there are simply more of them. Beech built 1954 of the “long nose” B55s from 1964 through 1982, not including about 70 T-42A versions for the U.S. Army. Among a number of minor refinements during this time was an increase in gross weight to 5100 pounds, starting with S/N TC-955 in mid-1965. Earlier B55s were eligible for the higher gross through a Beech STC kit.

 

Further refinements of the B55

Model years 1974 and up, they have a single fueling point in each wing. In 1977 corrosion proofing was improved. Beginning in 1978 the B55 would be produced with outboard fuel selectors.

The big-engine version arrived two years after the B55. The C55 Baron appeared in 1966 with a 12-inch longer fuselage and 285-HP Continental IO-520C engines. The “little Baron with the big engines” also was certified with a gross weight of 5300 pounds. The airplane was redesignated the D55 in 1968 and the E55 in 1970. It, too, was dropped from production in 1983, after 1201 were built, 451 Cs, 316 Ds and 434 Es.
