MT-Propeller approved for Cessna 414As

German company MT-Propeller has received an FAA STC for the installation of a 4-blade natural composite propeller on the Cessna 414A.

The STC applies to airplanes powered by TSIO-520-N or -NB or TSIO-520-NB engines modified per FAA STC SE4327SW, SE09104SC, or SE091261SC, according to company officials.

According to MT-Propeller Vice President Martin Albrecht, the installation has the following advantages:

• Shorter takeoff distance by approximately 6%
• Enhanced climb by up to 5% to 8%
• Cruise performance increased by approximately 3 to 5 kts
• Approximately 20 pounds less weight than the original propellers

MT-Propeller natural composite blades provide “significant inside and outside noise reduction,” he added, noting they have no life limitation and are repairable in case of a FOD.
