Sporting a distinctive V-shaped
or “butterfly” tail, the Beechcraft Bonanza set
the standard for the stylish yet well-equipped
aircraft for the private pilot, albeit one who
could afford to fly in relative luxury. Since its
introduction in 1947, the Bonanza has been admired
as a “classic” in the aviation world, even earning
Fortune magazine's prestigious award in
1959 as one of the 100 best designed
mass-production products.
The Beech Aircraft Corporation,
confident in its manufacturing capacity after
building more than 7,000 combat aircraft during
World War II, positioned itself for the post-war
era by designing a revolutionary single-engine
aircraft with a V-tail configuration that trimmed
weight without compromising control. Company
founder Walter Beech envisioned a light aircraft
with a level of performance and comfort that would
distinguish it from the competition.
In theory, the Bonanza's V-tail
design uses only two surfaces to perform its
function as compared to the three surfaces of a
conventional straight-tail design. This reduction
in surfaces reduces both drag and weight, while
also lowering the probability of tail buffeting
from the wakes generated by the aircraft's wing
and canopy. Aircraft control response with the
V-tail is equivalent to that of a conventional
tail of 40 percent greater surface area.
Manufacturing costs for the V-tail design are also
lower because fewer parts are required to
fabricate only two surfaces instead of three.
The Bonanza (Model 35) made its
first test flight just after the war's end on
December 22, 1945, with pilot Vern Carstens at the
controls. This flight test phase would be marred
by a 1946 accident when the V-tail broke away from
the Bonanza's fuselage during a high-speed dive,
killing the test pilot but sparing the flight
engineer. Walter Beech ordered continued
aggressive testing of the Bonanza, eventually
accumulating more than 1,500 hours of flight time
without further incident.
The post-war boom in civil
aviation translated into marketing success for
Beech – more than 1,400 advance orders for new
Bonanzas were placed even before the start of
production. In March 1947, the U.S. Civil
Aeronautics Authority issued its Approved Type
Certificate for the Bonanza (Model 35) and
full-scale production of the new aircraft
commenced.
Transforming its wartime
production expertise to the consumer sector, the
Beech Aircraft plant in Wichita, Kansas, quickly
mobilized to meet the demand for the new aircraft,
delivering about 1,000 Bonanzas by the end of 1947
at the then-hefty price of $7,975. The Bonanza
quickly developed a solid reputation as a
versatile personal and business aircraft and would
soon make an impact on the non-flying public as
well.
Beech decided to showcase the
Bonanza's performance and reliability by
sponsoring William Odom's world-record attempt for
the longest non-stop solo flight. Odom's aircraft,
nicknamed the Waikiki Beech, was specially
modified with additional fuel and oil reserves,
increasing the Bonanza's range more than fivefold
to 5,500 miles (8,851 kilometres).
From March 6-8, 1949, Odom flew
the Waikiki Beech across the Pacific from
Hawaii to California, then cross-country to
Teterboro Airport, New Jersey. Flying 5,273 miles
(8,486 kilometres) in just over 36 hours (while
burning only 272 gallons [1,030 litres] of fuel)
earned William Odom a place in aviation history;
tragically, he was killed in a racing accident
later that year. The Waikiki Beech Bonanza
was subsequently donated to the Smithsonian
Institution's collection of historic aircraft.
In a calculated move to
increase sales, Beech introduced a radical
re-design of the Bonanza on September 14, 1959.
The aircraft's trademark V-tail was replaced with
a conventional straight tail, resulting in a new
variant initially dubbed the “Debonair.” (Later
models would revert back to the “Bonanza”
moniker). The current straight-tail model, the
Bonanza 36, was first built in 1968 and is still
in production today.
The basic V-tail Bonanza design
also continued to evolve over the next two decades
– the fuselage was lengthened, followed by the
introduction of a fuel-injected engine -
increasing the aircraft's overall performance. A
few Bonanzas were even pressed into service as
military drones during the Vietnam War.
The Bonanza features a fully
retractable undercarriage, making it both
streamlined and aerodynamic while airborne,
capable of carrying up to five passengers and 277
pounds (126 kilograms) of luggage stowed behind
the rear seats. First introduced in the 1970s, the
V35B model Bonanza was powered by a 285-horsepower
(213-kilowatt) Continental flat-six piston engine
with a 44-gallon (167-liter) fuel capacity. The
V35B was capable of cruising at 157 miles per hour
(253 kilometres per hour) at 8,000 feet (2,438
meters), with a maximum speed of 210 miles per
hour (338 kilometres per hour) (at sea level) and
a range of 1,020 miles (1,642 kilometres).
The 10,000th Bonanza
came off the production line in February 1977, but
five years later, Beech discontinued production of
the V-tail Bonanza to concentrate solely on the
straight-tail Bonanza 36. Concerns over the safety
of the V-tail design (and the resultant liability)
undoubtedly played a major role in that decision.
Independent studies found that the V-tail Bonanza
had a fatal in-flight failure rate 24 times higher
than the straight-tail version; a possible cause
is the greater stress placed on the V-tail
aircraft's tail and fuselage during pitch and yaw
manoeuvres than on the straight-tail version.
Olive Ann Beech, Walter's wife,
became president and CEO of Beech Aircraft
following her husband's unexpected death from a
heart attack on November 29, 1950, and remained at
the company's helm until 1968, when she assumed
the role of chairman at age 65. Beech Aircraft
ceased to exist as an independent entity when it
accepted a takeover bid from Raytheon Corporation
on October 1, 1979. Olive Ann Beech, arguably the
most successful female executive in aviation
history, died on July 6, 1993, at the age of 89.
In May 1996, the Bonanza
achieved another milestone when the 3,000th
straight-tailed Model 36 rolled off the production
line, and 1997 marked the 50th
anniversary of continuous Bonanza production.
The Bonanza 35/36 holds the
distinction of one of the most successful aircraft
in aviation history, with more than 17,000 built,
as well as one of the most prolific, remaining in
continuous production from 1947 to this day.
