MT-Propeller

What MT-Propeller does

MT-Propeller Entwicklung GmbH is a German privately-held manufacturer of natural composite propellers for piston and turboprop aircraft, founded in 1981 by Gerd Mühlbauer and headquartered at Straubing Airport in Atting, Germany. The company produces a portfolio of 30+ certified propeller models ranging from 2-blade hydraulic and electric constant-speed propellers through 5-blade scimitar designs to the world-first 7-blade Silent 7 platform, plus a 4-blade Warbird propeller for historic aircraft and rotors/actuation systems for helicopter applications. Underlying technology centers on natural composite blades with bonded nickel alloy or stainless steel leading edges, offering unlimited blade life, FOD repairability, and industry-leading vibration damping relative to aluminum or foam-core alternatives. The company holds 230+ Supplemental Type Certificates (STCs) across EASA, FAA, TCCA Canada, ANAC Brazil, AFAC Mexico, CAA UK, and other authorities, with no active Airworthiness Directives on its products.

MT-Propeller operates three production facilities in Germany (15,000 sqm headquarters plus a 5,000 sqm dedicated composite blade plant), with regional service entities in Florida (MT-Propeller USA), Czech Republic (Avia Propeller), and Ontario, Canada (MT-Propeller Canada, a joint venture with AMK Aviation established April 2026). The fleet has accumulated over 200 million flight hours across 34,500+ propeller systems and 135,000+ blades, served by a global network of 62 factory-certified service centers. The company serves as OEM supplier for more than 90% of the European aircraft industry and 55% of the US aircraft industry, with named OEM customers including Pilatus, Cessna, Piper, Cirrus, Diamond, Beechcraft, and Mooney.

Revenue is generated through four streams: OEM propeller sales to aircraft manufacturers, aftermarket STC kit sales to aircraft owners and operators, service/repair/overhaul (provided through subsidiary MT-Propeller Gerd Muehlbauer GmbH, FAA and EASA Part 145 certified, servicing both MT-Propellers and competitor brands McCauley, Hartzell, Sensenich, Woodward, and Goodrich), and spare parts. The business is founder-owned, organically financed, with approximately 280-285 employees worldwide and Bavaria's Best 50 recognition in 2024 for above-average five-year sales and headcount growth.

Expansion highlights5 records

Others

• Garmin: Garmin supplies avionics and the EIS (Engine Information System) that integrates with MT-Propeller's STC installations (e.g., Piper Meridian PT6A-135A conversion). Garmin is an enabling ecosystem participant rather than a competitor, but its product roadmap and certification priorities materially affect MT-Propeller's STC economics.

Direct peers

• Sensenich Propeller: Sensenich is a US-based propeller manufacturer serving the light GA, experimental, and ultralight segments. While smaller than Hartzell or MT-Propeller, it competes in fixed-pitch and two-blade constant-speed segments that overlap with MT-Propeller's lower-power product lines.
• WhirlWind Propellers: US-based composite propeller manufacturer focused on experimental, light sport, and certified GA aircraft. WhirlWind competes with MT-Propeller in the natural composite propeller segment, particularly for the experimental and LSA categories where MT-Propeller is expanding.
• Hartzell Propeller: Hartzell is the largest US general aviation propeller manufacturer and MT-Propeller's most direct global competitor. It sells OEM propellers to most of the same US airframers (Cessna, Piper, Beechcraft) and competes head-to-head in the STC aftermarket where MT-Propeller's 230+ STCs overlap heavily.
• McCauley Propeller (Textron Aviation): McCauley, now part of Textron Aviation (Cessna parent), produces propellers primarily for Cessna aircraft and supplies the broader GA aftermarket. It is the third major propeller OEM alongside MT-Propeller and Hartzell, with deep installed base on Cessna platforms that MT-Propeller targets via STCs.
• Hoffmann Propeller: German-based composite propeller manufacturer serving general aviation and motor glider segments. Hoffmann is a regional European competitor to MT-Propeller with overlap in the light aircraft and Rotax-powered segments, though smaller in scale and STC coverage.
• Duc Propellers: French propeller manufacturer specializing in composite propellers for general aviation and military applications. Duc competes with MT-Propeller in the European composite propeller market for piston and light turboprop aircraft, including on Cirrus and Diamond platforms.

Emerging players

• Airmaster Propellers: New Zealand-based propeller manufacturer producing composite propellers for light and sport aviation. Airmaster is a smaller emerging competitor to MT-Propeller in the natural composite segment, primarily focused on Rotax-powered light aircraft.

Regional players

• Woodcomp Propellers: Czech Republic propeller manufacturer producing wooden and composite propellers primarily for European GA and ultralight markets. Woodcomp competes with MT-Propeller in the Central/Eastern European market where MT-Propeller already operates via Avia Propeller s.r.o.

Broad incumbents

• Pratt & Whitney Canada (P&WC): P&WC manufactures the PT6A turboprop engines that MT-Propeller's MTV-27 and MTV-47 propellers are commonly paired with (e.g., Pilatus PC-12, King Air 350). While not a propeller competitor, P&WC is the dominant engine supplier across MT-Propeller's target platforms and a key ecosystem partner for the X-Range Meridian conversion.
