Source measurement	—	The PA-23 was the first twin-engined Piper aircraft, and was developed from a proposed "Twin Stinson" design, inherited when Piper bought the Stinson Division of the Consolidated Vultee Aircraft Corporation . The prototype PA-23 was a four-seat, low-wing, all-metal monoplane with a twin tail , powered by two 125 hp Lycoming O-290 -D piston engines; it first flew on March 2, 1952.
