3-blade MT-Propeller supplemental type certified on Rockwell Commander 114, 114A, 114B, 114TC
MT-Propeller Entwicklung GmbH has received the FAA STC SA03657NY for the next generation 3-blade scimitar composite propeller MTV-9-B/198-52 on the Rockwell Commander 114, 114A, 114B, 114TC powered by the Lycoming engines IO-540-T4A5D, IO-540-T4B5D, IO-540-T4B5 and TIO-540-AG1A.

This installation is already certified by EASA STC 10054490.

MT-Propeller President Gerd Muehlbauer announced, that according to the certification flight tests the new 3-blade propeller installation on the Rockwell Commander 114, 114A, 114B, 114TC reduces ground roll & takeoff distance over 50 ft obstacle by 30m (98ft) and increases climb performance slightly.
No engine modification is nessecary for the installation of the MTV-9.
The cruising is very smooth and there is no speed penalty.

The propeller has approx. 8kg (17,6 lbs) less weight than the original 3-blade metal propeller.

The MT-Propeller natural composite blades provide significant inside and outside noise reduction for a jetlike vibration and noise signature. They have no life limitation and are repairable in case of an FOD.

They also provide best vibration damping characteristics for almost vibration free propeller operation and have bonded on stainless steel leading edges for superior erosion protection of the blades.

MT-Propeller is the world leading natural composite propeller manufacturer with 30 propeller models from 2-blade to 6-blade hydraulically controlled variable pitch propeller, for engines producing up to 5000hp, and 2-blade to 4-blade electrically controlled variable pitch propeller, for engines producing up to 350hp as well as two blade fixed pitch propellers.
Over 30 years ago, the first MT-Propeller was shipped.

The high performance, light weight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels or hovercraft.
