Bay Super V Bonanza
Beechcraft T-34 Mentor
The Beechcraft Bonanza is an American general aviation aircraft introduced in 1947 by The Beech Aircraft Corporation of Wichita, Kansas. As of 2010[update], it is still being produced by Hawker Beechcraft, and has been in continuous production longer than any other airplane in history. More than 17,000 Bonanzas of all variants have been built.
Design and development
At the end of World War II, two all-metal aircraft emerged, the Model 35 Bonanza and the Cessna 195, that represented very different approaches to the premium-end of the postwar civil aviation market. With its high wing, seven-cylinder radial engine, fixed tailwheel undercarriage and roll-down side windows, the Cessna 195 was little more than a continuation of prewar technology; the 35 Bonanza, however, was more like the fighters developed during the war, featuring an easier-to-manage horizontally-opposed six cylinder engine, a rakishly streamlined shape, retractable nosewheel undercarriage (although the nosewheel initially was not steerable, or castering) and low-wing configuration.
Designed by a team led by Ralph Harmon, the model 35 Bonanza was a relatively fast, low-wing monoplane at a time when most light aircraft were still made of wood and fabric. The Model 35 featured retractable landing gear, and its signature V-tail (equipped with a combination elevator-rudder called a ruddervator), which made it both efficient and the most distinctive private aircraft in the sky. The prototype 35 Bonanza made its first flight on 22 December 1945, with the first production aircraft debuting as 1947 models. The first 30–40 Bonanzas produced had fabric-covered flaps and ailerons, after which, those surfaces were covered with magnesium alloy sheet. The V-tail design gained a reputation as the "forked-tail doctor killer", due to crashes by overconfident amateur pilots with high-level skills outside aviation, fatal accidents, and in-flight breakups. "Doctor killer" has sometimes been used to describe the conventional tailed version as well.
In 1982 the production of the V-tail Bonanza stopped but the conventional-tail Model 33 continued in production until 1995. Still built today is the Model 36 Bonanza, a longer-bodied, straight-tail variant of the original design, introduced in 1968.
All Bonanzas share an unusual feature: The yoke and rudder pedals are interconnected by a system of bungee cords that assist in keeping the airplane in coordinated flight during turns. The bungee system allows the pilot to make coordinated turns using the yoke alone, or with minimal rudder input, during cruise flight. Increased right-rudder pressure is still required on takeoff to overcome torque and P-factor. In the landing phase, the bungee system must be overridden by the pilot when making crosswind landings, which require cross-controlled inputs to keep the nose of the airplane aligned with the runway center line without drifting left or right. This feature started with the V-tail and persists on the current production model.
In January 2012 the Australian Civil Aviation Safety Authority issued an airworthiness directive grounding all Bonanzas, Twin Bonanzas and Debonairs equipped with a single pole style yoke and that have forward elevator control cables that are more than 15 years old until they could be inspected. The AD was issued based on two aircraft found to have frayed cables, one of which suffered a cable failure just prior to take-off and resulting concerns about the age of the cables in fleet aircraft of this age. At the time of the grounding some Bonanzas had reached 64 years in service. Aircraft with frayed cables were grounded until the cables were replaced and those that passed inspection were required to have their cables replaced within 60 days regardless. The AD affected only Australian aircraft and was not adopted by the airworthiness authority responsible for the type certificate, the US Federal Aviation Administration. The FAA instead opted to issue a Special Airworthiness Information Bulletin (SAIB) requesting that the elevator control cables be inspected during the annual inspection.
QU-22 Pave Eagle
The QU-22 was a Beech 36/A36 Bonanza modified during the Vietnam War to be an electronic monitoring signal relay aircraft, developed under the project name "Pave Eagle" for the United States Air Force. A reduction geared Continental IO-520 engine was used to reduce its noise signature, much like the later Army-Lockheed YO-3A. These aircraft were intended to be used as unmanned drones to monitor sensors along the Ho Chi Minh Trail in Laos and report troop and supply movements. When the project was put into operation in 1968, however, the drones were all flown by pilots of the 554th Reconnaissance Squadron.
Six YQU-22A prototypes (modifications of the Beech 33 Debonair) were combat-tested in 1968, and two were lost during operations, with a civilian test pilot killed. Twenty-seven QU-22Bs were modified, 13 in 1969 and 14 in 1970, with 6 lost in combat. Two Air Force pilots were killed in action. All of the losses were due to engine failures or effects of turbulence.

The Beechcraft Model 40A was an experimental twin-engined aircraft based on the Bonanza. Only one prototype was built in 1948. It featured a unique over/under arrangement of two 180 hp Franklin engines mounted on top of each other and driving a single propeller. The plane had a different engine cowl from a standard Bonanza, and the nose gear could not fully retract, but otherwise it greatly resembled the production Bonanzas of the time. Certification rules demanded a firewall be fitted between the two engines, however, thus stopping development. The status of the prototype is unknown.
The Bonanza is popular with air charter companies, and is operated by private individuals and companies.

- In January 1949, the fourth Bonanza to come off the production line was piloted by Captain William Odom from Honolulu, Hawaii to the continental United States (2,900 statute miles), the first light airplane to do so. The airplane was called "Waikiki Beech", and its 40-gallon (150 L) fuel capacity was increased (using fuselage and wing tanks) to 268 gallons (1010 L), which gave a still-air range of nearly 5,000 statute miles.
- In March 1949, Captain Odom piloted "Waikiki Beech" a distance of 5,273 miles (8,486 km) from Honolulu to Teterboro, New Jersey, setting a nonstop record. The flight time was 36:01 hours, at an average speed of 146.3 miles per hour (235.4 km/h), consuming 272.25 US gallons (1,030.6 l; 226.70 imp gal) of fuel. After that flight, the airplane was donated to the Smithsonian Institution's National Air Museum, as the National Air and Space Museum was then called.
- On 7 October 1951, an American congressman from Illinois, Peter F. Mack, Jr., began an around-the-world trip in "Waikiki Beech", on loan from the Museum and reconditioned at the Beech factory, and renamed "Friendship Flame". He spent 15 weeks traveling through 30 countries (223 hours flight time). The plane was again refurbished in 1975 and returned to the National Air and Space Museum. It is still on display there, with both names painted on its sides.
Accidents and incidents
- On 3 February 1959, Buddy Holly, Ritchie Valens, The Big Bopper, as well as the pilot Roger Peterson died when their Beechcraft Bonanza 35, registration N3794N, crashed shortly after takeoff at night in foul weather. This accident has become known as The Day the Music Died.
- On July 31, 1964, country music star Jim Reeves and his pianist Dean Manuel died when the Beechcraft Debonair Reeves was piloting crashed in the Brentwood area of Nashville during a violent thunderstorm. The wreckage and bodies were discovered on 2 August 1964 amid dense foliage in a wooded area just off Baxter Lane next to US Interstate 65.
- In February 1981, Apple Computer cofounder Steve Wozniak crashed his Beechcraft Bonanza while taking off from Santa Cruz Sky Park. The NTSB investigation revealed Wozniak did not have a "high performance" endorsement (making him legally unqualified to operate the airplane) and had a "lack of familiarity with the aircraft." The cause of the crash was determined to be a premature liftoff, followed by a stall and "mush" into a 12-foot embankment. Wozniak later made a full recovery, albeit with a case of temporary retrograde amnesia.
- On 19 March 1982, Ozzy Osbourne guitarist Randy Rhoads was killed when the wing of the Bonanza F35 he was riding in hit the band's tour bus and the plane crashed into a tree and a nearby residence. The pilot and another passenger were also killed. The NTSB cited the causes of the crash as poor judgement, buzzing and misjudged clearance as well as indicating that the use of the aircraft was not authorized by the aircraft's owner.
- On 13 March 2006, game show host Peter Tomarken crashed his Bonanza A36 into Santa Monica Bay while climbing from Santa Monica Airport in California. He was en route to San Diego to pick up a cancer patient who needed transportation to UCLA Medical Center for treatment. Tomarken and his wife were killed in the crash.
