The Piper PA-44 Seminole is an American twin-engined light aircraft manufactured by Piper Aircraft. Developed from the single-engined Piper Cherokee, the PA-44 is primarily used for multi-engined flight training. 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.
The first prototype Seminole made its maiden flight in May 1976 and the type was publicly announced on February 21, 1978. Changes were limited to modifications to the aircraft's electrical systems and instrumentation. Production was stopped again in 1990 after 29 more aircraft had been delivered owing to Piper's financial problems. Production restarted again in 1995.
