The Cessna 340 is a six-seat, two- piston-engine powered aircraft from the US manufacturer Cessna with a pressurized cabin .
The otherwise almost identical Cessna 335 did not have a pressurized cabin.
history
In December 1971, Cessna announced the introduction of a "Model 340" with a pressurized cabin based on the Cessna 310 . Development had already started in 1969. The accident of the prototype with the aircraft registration number N2340C in April 1970, in which the test pilot was killed, delayed the project considerably. A second prototype first flew in 1971. The Cessna 340 combined the wings and landing gear of the Cessna 414 with a rear similar to the Cessna 310 and a new fuselage.
After 350 copies had been built, the production of the Cessna 340 ended in 1976, instead the improved second series version 340A was produced.
Parallel to the production of the 340A, the development of a version of the 340A without a pressurized cabin, the "Model 335", began in 1977. The prototype flew for the first time on December 5, 1978, the first production aircraft on August 13, 1979. This version of the 340A, which was 74 to 82 kg lighter, was offered from 1979 onwards. However, Cessna only sold 65 copies; the production of this version ended in 1980.
In 1984 production was ended after a total of 1363 Cessna 335/340 machines had been built.
construction
The Cessna 340 was designed as a cantilever all-metal low-wing aircraft, the construction of which was based on the Cessna 310 and 414 to a considerable extent.
The nose wheel landing gear is electrically retractable, has one wheel per landing gear leg and hydraulically operated brakes on the main landing gear. The landing flaps are operated electrically.
In the passenger cabin, which is designed for four people, there are individual seats with adjustable backrests. The cabin is accessible through a door on the rear left. A luggage compartment in the fuselage for a maximum of 159 kg is accessible via separate flaps, as well as two luggage compartments in the wings for 54 kg each and one in the rear cabin area for 154 kg.
Two air-cooled six-cylinder boxer engines from Continental (differences: see versions) drive three-bladed McCauley variable pitch propellers . The fuel is in a complex system of eight tanks: on the one hand six wing tanks, on the other hand 386 liters in the visually striking two wing tip tanks, 378 liters of which can be used. The tank capacity is a total of 783 liters, 768 liters of which are usable.
production
The Cessna 340, which was produced as the first variant, was replaced after 335 copies by the Cessna 340A, of which 948 were built by 1984 (end of production).
The production of the version Cessna 335 was stopped in 1980 after only 65 copies. According to a single other source, only 45 copies were produced; however, this can be excluded from various other sources using the serial numbers .
