The 320 Skyknight was developed from the 310F, which featured turbocharged TSIO-470-B engines and a fourth cabin side-window. The Skyknight was in production between 1961 and 1969 (the 320E was named the Executive Skyknight), when it was replaced by the similar Turbo 310.
The Cessna T303 Crusader is an American six-place light twin-engined aircraft built by Cessna Aircraft Company.
The new model, designated the T303 Crusader first flew on October 17, 1979 with the first deliveries being made in October, 1981. The T303 is an all-metal low-wing six-seat twin-engined aircraft with a retractable tricycle undercarriage. At the time, it was the first all-new production twin built by Cessna in over a decade.
Cessna introduced its "revolutionary" tandem twin 336 Skymaster in 1963. With centerline thrust and twin tail booms, the Skymaster promised to be everything a standard light twin wasn't—namely, much easier and safer to fly on one engine. In late 1964, Cessna Aircraft introduced the 337 Super Skymaster with more powerful engines and retractable gear. The pressurized and turbocharged P337 came on the scene in the 1973 model year.
The Cessna 421 Golden Eagle is an American six or seven seat twin-engined light transport aircraft, developed in the 1960s by Cessna as a pressurised version of the earlier Cessna 411.
The Cessna 421 was first produced in May 1967. The 421A appeared in 1968 and the aircraft was redesigned in 1970 and marketed as the 421B. In 1975 the 421C appeared which featured wet wings, the absence of wingtip fuel tanks and landing gear that was changed from straight-leg to a trailing-link design from the 1981 model year onwards.
The Cessna Model 411 is a 1960s American twin-engined, propeller driven light aircraft built by Cessna Aircraft. It was that company's largest business aircraft when it first flew in 1962, other than a four-engined airliner developed during the 1950s, which was not put into development.
The 411 is an eight-seat low-wing twin-engined cabin monoplane retractable landing gear and an airstair entrance door. It has two 340 hp (254 kW) Continental GTSIO-520-C engines with three-bladed propellers. It has a retractable tricycle landing gear and an airstair door.
The Cessna Model 404 Titan is an American twin-engined, propeller-driven light aircraft built by Cessna Aircraft. It was that company's largest twin piston-engined aircraft at the time of its development in the 1970s.
It is powered by two 375 hp/280 kW turbocharged Continental Motors GTSIO-520 piston engines. Two versions were offered originally; the Titan Ambassador passenger aircraft for ten passengers, and the Titan Courier utility aircraft for passengers or cargo.
By early 1982 seven different variants were available, including a pure cargo version, the Titan Freighter. The Freighter was fitted with a strengthened floor, cargo doors, and its interior walls and ceiling were made from impact-resistant polycarbonate materials to minimize damage in the event of cargo breaking free in-flight.
The Cessna 402 are series of 6 to 10 seat, light twin, piston engine aircraft. This line was manufactured by Cessna from 1966 to 1985 under the name Businessliner.
All seats are easily removable so that the aircraft can be used in an all-cargo configuration. The Cessna 402 is not pressurized, nor were they particularly fast for the installed horsepower. Instead, Cessna intended them to be inexpensive to purchase and operate.
The Cessna 401 are series of 6 to 10 seat, light twin, piston engine aircraft. This line was manufactured by Cessna from 1966 to 1985 under the name Utiliner.

The Cessna 340 is a twin piston engine pressurized business aircraft that was manufactured by Cessna.
The 340 is a six-seat aircraft, with four passenger seats, an aisle and an airstair door. The tail and landing gear were based on the Cessna 310's units, while its wings were from the Cessna 414. The 340's primary selling feature was its spacious, pressurized cabin, the first in a light twin.
The Cessna 425, known as the Corsair and later as the Conquest I, is an eight-seat American pressurized turboprop twin-engined light aircraft. Now out of production, it was built by Cessna Aircraft of Wichita, Kansas between 1980 and 1986.
The 425 was very easy to fly and was noted by reviewers for its spacious cabin with large windows for good visibility and comfortable seats. The original Corsair was developed into the Conquest I by customer demand for more cabin space and a higher maximum takeoff weight. Cessna worked on upgrades that would allow more cabin space and passengers. Essentially, the upgrades increased maximum takeoff weight.
The Cessna 441 Conquest II was the first turboprop powered aircraft designed by Cessna and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8-9 passenger turbine development of the Cessna 404.
The aircraft has retractable tricycle landing gear and on takeoff has a ground roll of 1,785 ft (544 m). The high aspect ratio wings use bonded construction techniques.
The Conquest is powered by two Garrett TPE331 turboprops powering two four-bladed McCauley propellers. A 441 with Pratt & Whitney Canada PT6A-112 turboprops was flown in 1986 but did not enter production.
