Development and history

The Cessna 310 was the American manufacturer's first two-engine new development after the Second World War. The first flight took place on January 3, 1953. A total of 4 to 6 people fit on the plane. Delivery began the following year. About 6,000 machines were produced in the various series. Many of them are still in use today.

As a military machine it was initially called the L-27A / B, later the U-3A / B, known as the " Blue Canoe ".

The Cessna 320 Skyknight was developed from the Cessna 310F. With 6 seats it had one more, an additional rear cabin window, a 72 kg increased maximum take-off weight of 2265 kg and Continental TSIO-470-B turbocharged engines . A seventh seat was optionally available from the 320B. The maximum take-off weight increased up to 2406 kg for the last versions 320E and 320F. From 1961 to 1969 a total of 577 units were built.

Incidents

• On October 25, 1974, a private Cessna 310 (registration number G-APTK ) coming from East Midlands Airport crashed into a field 1200 meters east of Norwich Airport while approaching . The pilot, the only occupant, was killed. The cause was the defect in the right flap drive, which caused this flap to enter the curve on the final approach and loss of control.
