Bell 427

Bell 427 – a multi-purpose light helicopter.

Designed by the American company Bell Helicopter Textron, the Korean company Samsung Aerospace Industries took part in the creation. The prototype was the Bell 407 model with a completely redesigned fuselage and an 8 percent enlarged cockpit. The helicopter uses a new dynamic system, which is similar to that installed on the BellOH58D military helicopter, which also includes the main four-blade propeller completely made of composite materials.

A full-scale layout was first presented at an exhibition in September 1996 in Farnborough. The first flight took place at the end of 1997. In 1999, the helicopter was certified. The first helicopters were ordered by Petroleum Helicopters in 2000.
