The Cessna 206 series received FAA Supplemental Type Certification (STC) for a five-blade MT-Propeller.

According to MT-Propeller, the new configuration reduces the maximum propeller rpm to 1,900. The configuration has already received certification from the European Union Aviation Safety Agency (EASA). MT-Propeller president Gerd Muehlbauer boasts the following perks to the five-blade configuration:

  • Improved erosion protection from bonded-on nickel alloy leading edges
  • 6-8 ktas cruise performance improvement
  • Improved ramp appeal
  • Smaller prop diameter with increased ground clearance
  • German noise regulation compliant

MT-Propeller states the composite blades have no life limitation and are repairable in the event of incidents involving foreign object debris (FOD).

“The high performance, lightweight and durable MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels, and hovercraft. MT-Propellers can be developed for nearly every aircraft type from motor gliders to regional airliners,” the company said in a statement.

This STC is just the latest of the company’s nearly 200 STCs worldwide. MT-Propeller also serves as the OEM supplier for more than 90 percent of the European aircraft industry, and 30 percent of the American aircraft industry.
