Key Takeaways:

MT Propeller has received an FAA supplemental type certificate (STC) for a new three-bladed composite propeller (MTV-12-B-C-F/CF(L)183-59) for the Piper PA-34-200 Seneca I, which was already certified by EASA.
This new composite propeller provides several benefits, including a bonded stainless-steel leading edge for erosion protection, unlimited blade life, and greater ground clearance.
Operators can expect slight improvements in takeoff performance, almost vibration-free operation, and a weight reduction of approximately 20 pounds compared to the original propellers.
