MT-Propeller

MT-Propeller Entwicklung GmbH is a German manufacturer specialising in the design and production of high-performance natural-composite propellers. The company occupies a specific niche in the general aviation and special mission sectors, providing propeller systems for piston engines and turboprop applications. Its primary technological focus is the development of multi-blade systems using wood-based cores reinforced with fibre-reinforced plastics and stainless steel leading edges, intended to reduce airframe vibration and weight compared to traditional all-metal designs. The organisation’s portfolio includes propeller certifications for a vast range of airframes, notably those produced by Beechcraft, Cessna, Piper, and Diamond Aircraft. Their systems are frequently selected for retrofitting through Supplemental Type Certificates (STC) and as original equipment for regional commuters and utility aircraft. They maintain close technical cooperation with engine manufacturers such as Lycoming, Continental, and Pratt & Whitney Canada to ensure compatibility with various powerplants and governors. Prospective buyers or technical partners should verify the specific STC status for their particular aircraft and engine combination before engagement. It is essential to confirm the maintenance interval requirements for the natural-composite blades, which may differ from metallic counterparts. Verification of the regional service centre network is also recommended to ensure long-term support for overhaul and repair cycles across different jurisdictions.
