Piper PA-46 Malibu mode, airplane. Announced in November 1982, the Malibu was intended to compete against Cessna's pressurized P210 Centurion, plus older light business twins. Designed with the aid of CAD/CAM (Computer Aided Design/Computer Aided Manufacture), an unpressurized experimental prototype, the PA-46-300T, flew for the first time on November 30, 1979. The prototype for the first production model, the pressurized PA-46-310P, first flew in August 1982. Certification was awarded in September 1983, with production deliveries from that November.
