Piper PA-44 Seminole
The Piper PA-44 Seminole is essentially a twin-engine version of the popular Piper Cherokee series of small, single-engine flight training aircraft. Like its single-engine counterparts, it is primarily used for twin-engine flight training. It was built in 1979-82, in 1989-90, and again since 1995.
The Seminole is equipped with two 180-hp (135 kW) Lycoming engines, and it is often complained that the aircraft is greatly under-powered, especially for engine-out training (leading to the affectionate and awkwardly-rhyming moniker "No-Go Seminole" to some). However, the Seminole's single-engine performance is similar to that of many other popular light twins. A version built in 1981-82 featured turbocharged 180-hp (135 kW) Lycoming engines, which offer a significant improvement in performance at high density altitude.
The aircraft makes an effective multi-engine trainer, as the propellers are "counter-rotating" (with the left propeller rotating right and the right propeller rotating left), thus eliminating the critical engine and making the aircraft more controllable in the event an engine needs to be shut down or fails.
Other than having two engines, it is further distinguished from the majority of the Cherokee trainer line in having a high T-tail; in this, it is similar to the Arrow IV. This design is highly similar to the Beechcraft Duchess.
The PA-44 is used for multi-engine training by Bridgewater State College, Florida Institute of Technology, Bowling Green State University, Lewis University, Middle Tennessee State University, Kent State University, Minnesota State University, Mankato, Daniel Webster College, Western Michigan University, Embry-Riddle Aeronautical University, University of North Dakota, Sault College, Purdue University and FlightSafety International Academy in Vero Beach, Florida, University of Illinois - Institute of Aviation, Parks College at Saint Louis University.
