Piper PA-44 Seminole

A popular trainer aircraft used by flight instructors in a lot of groundschools today is the Piper PA-44 Seminole. An American twin-engined light aircraft manufactured by Piper Aircraft. The PA-44 is a development of the Piper Cherokee single-engine aircraft and is primarily used for multi-engine flight training.

The Seminole was built in 1979-82, in 1989-90, and again since 1995.

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 an engine needs to be shut down or fails.[4]

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).

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

The PA-44 features a high T-tail similar to the T-tailed Arrow IV. The Seminole resembles the competitive Beechcraft Duchess.

It is a popular rental aircraft used by private pilots today as well.
