Design and Development
Cessna 441 features retractable tricycle landing gear. It needs 544 metres of run on the ground to takeoff. 2 Garrett TPE331 turboprops power the aircraft with 2 4-bladed McCauley propellers. Cessna flew a model with turboprops supplied by Pratt & Whitney Canada PT6A-112 in 1986. However, it later entered into commercial production.

Most of the 441 models by Cessna have gone through modification with the installation of Garrett TPE-331-10 engines as replacement for the earlier older version of the engine that the aircraft was shipped with. The modification has increased the horsepower that the aeroplane can generate as well as fuel efficiency, service ceiling and range of the plane. Besides, it has considerably reduced the maintenance cost. Therefore, the resale value of modified Cessna 441 is greater than that of the original versions.

Moreover, the conversion from the standard 3-blade propellers to the 4-blade propellers of Hartzell with shorter diameter has improved the climb rate of Cessna 441 by 1.01 m/s or 200 f/m. It has improved the ground clearance, increased the cruise speed of the aircraft by 9 km/h or 5 km and reduced the cabin noise too.
