The Piper PA-44 Seminole is an American twin-engined light aircraft manufactured by Piper Aircraft.[1] Developed from the single-engined Piper Cherokee, the PA-44 is primarily used for multi-engined flight training.[1][2] The Seminole has been built in three production runs; from 1979 to 1982, 1989 to 1990, and continuously since 1995.

Design and development

The first production Seminoles are equipped with two 180 hp (135 kW) Lycoming O-360-E1A6D engines. The right-hand engine is a Lycoming LO-360-E1A6D variant, which turns in the opposite direction to the left-hand engine. This feature eliminates the critical engine and makes the aircraft more controllable in the event that an engine needs to be shut down or fails.[3][4]

The first prototype Seminole made its maiden flight in May 1976 and the type was publicly announced on February 21, 1978.[5] The Seminole was first certified on March 10, 1978, and introduced as a 1979 model year in late 1978. Gross weight is 3800 lbs (1723 kg).[4]

Later production Seminoles were built with Lycoming O-360-A1H6 engines.[4]

The PA-44-180T Turbo Seminole version was certified on November 29, 1979. It features two turbocharged 180 hp (135 kW) Lycoming TO-360-E1A6D engines, which offer a significant improvement in performance at high density altitude. The Turbo Seminole had its takeoff gross weight raised to 3925 lb (1780 kg), while the landing weight remained at 3800 lbs (1723 kg).[4]

The PA-44 features a high T-tail similar to the T-tailed Arrow IV. The Seminole is visually similar to the Beechcraft Duchess.[2]

Production of both versions of the Seminole was stopped in 1982, after 361 Seminoles and 87 Turbo Seminoles had been built. Production of the normally aspirated PA-44-180 restarted in 1988.[6] Changes were limited to modifications to the aircraft's electrical systems and instrumentation.[7] Production was stopped again in 1990 after 29 more aircraft had been delivered owing to Piper's financial problems.[8] Production restarted again in 1995.[9]
