Beechcraft 35 Bonanza

1948 A35 Bonanza

 

First flown on 22 December 1945, in 1971 total sales were close to the 10,000.


A cantilever low-wing monoplane of all-metal construction, including the distinctive tail unit, the Model 35 has an enclosed cabin providing seating for a pilot and three or four passengers. From the outset the Model 35 has had retractable tricycle landing gear, but the original version had only a swivelling nosewheel: a steerable unit was introduced on the Model A35 in 1949. An optional feature throughout the years has been a landing gear safety system of Beech design. Named 'Magic Hand', this ensures that the wheels cannot be retracted accidentally on the ground, or a landing made with the wheels up. As first flown, power was provided by a 138kW Continental E-185-1 flat-six engine, but a variety of standard and optional powerplants have been installed during the long production run. When the company announced that full-scale production was to begin in March 1947, it already had a backlog of around 1,500 orders.


The Bonanza was introduced as a production model in 1947 and was labeled the Model 35. The first Bonanza 35 was delivered in 1947. In 1947, 1,299 were built.

 

Powered by a Continental 165 hp, the top speed was 184 mph and cruise 175 mph. Subsequent aircraft were designated A35, B35, C35, etc. until the S35, after which the letter V was placed in front of the model number and the lettering process began all over again. Early models were fitted with 185-hp powerplants and seated four persons. In 1952, the C-model appeared with enlarged tail surfaces and a 205-hp engine. The 225-hp Continental was first used in 1954 with the E35. The H35 utilized a 240-hp engine and the J through M models were fitted with 250-hp Continentals. The 260-hp engine was introduced in the N35, and the 285-hp engine first appeared in 1964 in the S35. Early-model Bonanzas are still highly competitive on the used plane market and are highly prized as personal transportation aircraft. All were four seaters until the S35, after which all have accommodations for up to six. Like other Bonanzas, the V35B model benefits from the new 15-degree flap setting and the 28-volt electrical system to support optional propeller deicing equipment. The V35B Bonanza is certificated in the utility category. This provides a 4.4-G positive maneuvering load factor compared with 3.8 Gs for the normal category.

V35B


From 1966 to 1970, Beech built a hand-ful of airplanes labeled the V35TC, V35ATC and V35BTC. These were turbo-charged versions of the V-tail Bonanza. Unfortunately, the program was nipped in the bud by the 1969-70 recession. Beech had to cut back somewhere, and the blown Bonanza was it.


At the beginning of 1972 Model V35B Bonanza 9,288 had been built.


Early 1979, Beech re-entered the turbo market with a new turbocharged Bonanza, the A36TC. During the nine years be-tween the demise of the V35BTC and the introduction of the A36TC, the normally as-pirated Model 36 became the best seller in the Bonanza line, so it was logical to turbo-charge it rather than bring back the V35BTC.


The most obvious physical difference be-tween the normally aspirated A36 and the A36TC is the presence of five sets of gills and louvers on the sides of the TC's cowling. Also, the cowl flaps have been replaced with fixed lips, as on early Debonairs. By contrast, the V35TC had an intricate arrangement of four cowl flaps. Beech originally used cowl flaps on the A36TC, too, but found them to be ineffective under certain conditions.


With its gills and louvers, along with some baffle changes, tests showed the A36TC could climb out at 110 knots (best-rate-of-climb speed) on a 100 degree day without over-heating. Under the demanding conditions of high altitude, maximum cruise power set-ting and high outside air temperature, the airplane will not exceed temperature limits, even at its maximum certificated altitude of 25,000 feet. The pilot never has to touch a cowl flap or install winter baffles, and sufficient cooling is not at the expense of an excessively rich mixture. In 1979 both the normally aspirated and turbo models have extended baggage areas behind the last row of seats that will accommodate 10 cubic feet and 70 pounds of bags, equalling the Baron 58's cabin baggage capacity. The large double doors to the rear of the cabin facilitate loading and can be removed for flight.


Production of Bonanzas of all types amounts to about 15,000, production extended over 35 years.


The Bonanza also provided the foundation for the design of the conventional-tailed T-34 Mentor, for many years a primary trainer for the US and foreign services.
