British Aerospace Jetstream 31

The British Aerospace Jetstream 31 is a small pressurised twin turboprop airliner developed from the earlier Handley Page Jetstream. When Scottish Aviation was nationalised into British Aerospace, the new owner re-engined the design with Garrett TPE331 turboprops, which gave more power and longer overhaul intervals, and offered it with 18 seats in a 2+1 layout. The Jetstream 31 first flew on 28 March 1980 and was certificated in the United Kingdom on 29 June 1982, and several hundred were built in the 1980s. An upgrade with more powerful engines flew in 1988 as the Jetstream Super 31, also called the Jetstream 32. Production of the 31 and 32 continued until 1993, by which time 386 had been built, and the Royal Navy used four as the Jetstream T.3 trainer.
