Bell47G series

horizontal rule



Derived from a long series of thorough and exhaustive tests to which the original Model 30 (1942 - flew in the Us spring of 1943) was subjected, the Model 47 saw an initial production run of 10 units (B47B) in 1946.

The B47B was awarded the world's first commercial helicopter license and certificate by the United States Civil Aeronautics Administration (CAA).

It was the fore runner of a long series which continued in production until 1972 incorporating numerous improvements and refinements learnt from tens of thousands of hours of world wide operational use.
