Beech Bonanza 33 (1970-1982) TE-768 through TE-1201

Beech 33 Debonair / Bonanza

The Model 33 Debonair flew for the first time in September 1959. It was basically similar to the Model 35 Bonanza, but had a conventional tail assembly in place of the “V”-type tail. The Debonair was produced in four-seat versions with a 225-hp Continental IO-470-J, six cylinder engine. It had a simplified interior and less elaborate equipment than the Model 35. In 1961, the aileron and elevator trim tabs were improved, and larger rear windows and a restyled cabin interior with bucket seats were featured. In 1966, the option of a 285hp powerplant was added.

The Debonair name was dropped in 1967 and the subsequent aircraft, now a part of the Bonanza family, were simply designated E33, F33 and G33. During these years all model numbers ending in “A” featured the 285- hp Continental. All others retained the 225-hp engine. In 1972, the G33 was introduced with a 260-hp Continental. Currently, only the F-33A remains in production. Since its introduction as the Beechcraft Debonair, approximately 3,100 Model 33s have been produced.

Recent standard features for all Bonanza models are a 15-degree approach flap setting and a 28-volt electrical system. The approach flaps are identical to the Baron models and will allow for a maximum extension speed of 175 mph. An improved electrical system speeds up the landing gear cycle and allows Bonanzas to be equipped with propeller deicing. Also, all late model Bonanzas offer increased oxygen capacity. Single-piece headliners and redesigned cabin sidewalls make for a clean appearance and reduced cabin sound levels. As of 1981 airspeed indicators read in knots only, and an electronic fuel-flow sensor has replaced the mechanical sensor to ensure greater gauge accuracy. (Plane and Pilot Magazine)

An M35 Bonanza with conventional fin and tailplane, one 225 hp Continental IO-470-J. The 33 Debonair seats up to 3 passengers plus 1 pilot. Despite aggressive pricing, the Debonair didn't take the market by storm. 233 were built.

Beech A33 Debonair (1961) serial numbers CD-225 through CD-232, CD-235, CD-237 through CD-240, CD-242 through CD-245, CD-251 through CD-387
The A33 came with extra rear side windows, improved interior trim, a hat shelf and a boost in gross weight, from 2900 to 3000 pounds – still less than the Bonanza-and the same Continental IO-470J, 225-HP engine. The A33 Debonair seats up to 3 passengers plus 1 pilot. Production amounted to 154.

The B33 Debonair seats up to 3 passengers plus 1 pilot. It remained in production until 1964 with 426 built.

Beech C33 Debonair (1965-1967) serial numbers CD-814 through CD-1118
The C33 in 1965 got another boost in gross weight, but this was more than offset by an increase in empty weight. There were several other minor improvements as well. For example, the earlier Debonairs had a bench rear seat. This was replaced by individual seats, and a practically useless fifth seat was offered as an option. Larger rear windows were made available, and the hat shelf was enlarged. By this time, all fuel was carried in leading-edge rubber bladders. Standard capacity was 50 gallons; 80 gallons was optional. The C33 remained in production through 1967. The C33 Debonair seats up to 4 passengers plus 1 pilot. 306 were built.

Beech C33A Debonair (1966-1967) serial numbers CE-1 through CE-170
But in 1966, Beech also brought out the precursor to what the Model 33 would become: the C33A. The big news here was the engine: The C33A was fitted with the V35 Bonanzas 285 HP Continental IO-520-B/BA, making it for all intents and purposes a straight-tailed Bonanza (although Bonanza purists maintain a “straight-tail” Bonanza is one of the early V-tail models, with narrow-chord ruddervators). Gross weight increased to 3300 pounds, 100 pounds shy of the same-year Bonanza. The only real changes to previous Debonair airframes involved adding cowl flaps for extra cooling, installing a different nosebug and canting the engine slightly down and right, same as was done on the S35 and subsequent V-tails equipped at the factory with an IO-520. The C33A Debonair seats up to 4 passengers plus 1 pilot. The C33A was built for two years, 1966 and 1967, with a total production run of 170.

Major differences between the -C and the -A are a strengthened tail, positive-pressure fuel pump and a cabin door that can be jettisoned. During aerobatic flight, only the two front seats were occupied and a quick release door was standard equipment, along with front seat shoulder harnesses, a g-meter and special fuel boost pump and unique checkerboard paint on wing and tail tips. Typical aerobatic maneuvers approved were aileron roll, barrel roll, inside loop, Immelman, Cuban eight and split-S. The E33C Bonanza seats up to 3 passengers plus 1 pilot. 25 Model E33C were built.

Beech F33 Bonanza (1970) serial  number CD-1235 through CD-1254
The F33, last of the 225 HP Bonanza 33s, was introduced in 1970 and lasted only a year, with 20 built. The 1970 Model F33 Bonanza was actually a refined Model E33, still using the Continental IO-470-K of 225 hp. F33 had restyled third cabin window of the Model V35B, “Speed Sweep” windshield, three gear down annunciator lights, redesigned sub panels and switches, a lower glare shield and Hartwell quick-opening latches for the engine cowling.

The F33 sibling with a 285 hp Continental IO-520-B engine and continued production until 1994. The F33A was produced in two versions with no model designations to differentiate them. The 1970 version was your short cabin version of the straight-tail Bonanza with a big motor and 26 of these were built. The 1971 version got the long cabin of the contemporary Bonanza which moved the aft bulhead back 19 inches. 34 were produced with the long fuselage, allowing two important benefits: a larger baggage door and six seat configurations previously available only in the Model V35B Bonanza. The 1971 F33A possessed all of the V35B´s glamour, both inside and out, with the only difference between airplanes being the choice of empennage design. The F33A Bonanza seats up to 3 passengers plus 1 pilot. 1501 were built before production stopped in 1994.

From 1973 on, all Model F33C Bonanzas featured the 19-inch longer fuselage and the same structural features of the earlier Model E33C aerobatic Bonanza. Powered by a 285 hp Continental IO-520-BB engine, the F33A seated four or five with optional fifth seat.
