On display at the Museum of Flight. Designed by Bill Lear, this prototype first flew on "Dec. 32, 1980", as recorded officially so that British government funding expiring in 1980 could continue to be enjoyed. Only three aircraft were built and they are all on display in US museums. The Lear Fan was built of composite materials which revolutionized the field of aviation, had a Y-shaped empennage and the pusher propeller was powered by a pair of P&W Canada PT6B-35F turboshafts. Ahead of its time, it ran into trouble with the FAA on gearbox issues.

First flown after designer Bill Lear's death, on 1 January 1981, the Lear Fan was made largely of composites and powered by two PT6 engines driving a single pusher propeller. Perhaps not surprisingly it never entered production.
