Piper PA-40 Arapaho

The Piper PA-40 Arapaho was an American six-seat, twin-engined cabin monoplane that Piper designed to replace the PA-39 Twin Comanche C/R, with a taller main landing gear and larger cabin windows than its predecessor. It used two counter-rotating 160 horsepower Lycoming IO-320 engines. The prototype was damaged in the June 1972 Lock Haven flood, flew on 16 January 1973 and crashed in spin trials that September, after which the design received a taller tailfin. The type was certified on 18 July 1974, but Piper cancelled the project in December 1974 rather than open a new production line during the recession, and the surviving aircraft served as company liaison aircraft.
