The success of the Jetstream 31 prompted British Aerospace to further develop the design, launching the stretched Jetstream 41. However, as Stephen Skinner explains, sales failed to live up to expectations.

The Jetstream 41 neatly filled a gap in British Aerospace’s range of three regional airliners comprising the 19-seat Jetstream 31, 64-seat ATP and the 70-94-seat Avro RJ. Initial market projections were for just under 400 Jetstream 41 sales in the 15 years up to 2003. British Aerospace’s (BAe’s) forecasts were given added weight when they were backed in an independent evaluation by Swiss aircraft manufacturer Pilatus, before it became a risk-sharing partner in the Jetstream programme.
