Better performance and better ice protection are two benefits of recently approved de-ice boots designed for Piper Twin Comanche by MT-Propeller. The FAA has granted the company a supplemental type certificate (STC) for de-ice boots for Piper PA-30/39.

According to MT-Propeller, STC SA04587CH covers the installation of the Goodrich Electric Propeller de-ice boots on Piper PA-30/PA-39s equipped with MT-Propeller MTV-12-C-C-F/CF(L)180-57. The company notes the de-ice boots must be installed in accordance with STC SA03563NY.

According to MT-Propeller, the MTV-12 MT-Propeller with the de-ice Boots provides numerous advantages:

  • If the aircraft encounters unexpected icing conditions, it will have unchanged performance from the propellers and less unbalance is expected.
  • Best vibration damping characteristics for almost vibration free propeller operations.
  • Bonded on a stainless steel leading edge for best erosion protection of the blades.
  • Enhanced take-off performance by approximately 15 percent (maximum takeoff weight at sea level on a standard day).
  • Enhanced single-engine climb performance by approximately 10 percent ( maximum takeoff weight at sea level on a standard day).
  • Enhanced cruise performance by two to three kts (maximum takeoff weight at sea level on a standard day)  
  • Unlimited blade life: FOD repairable blades.
  • Significant inside and outside noise reductions.

About the Company

MT-Propellers can be used on aircraft with piston engines and propeller turbines, as well as on airships, wind tunnels, and hovercraft. The company, which claims to be the leading natural composite propeller manufacturer, notes MT-Propellers can be developed for nearly every aircraft type, from motor gliders to regional airliners.

MT-Propellers has a factory-certified network of 62 service centers providing service and maintenance all over the world. 

The company offers 30 certified propeller models ranging from two-blade to seven-blade hydraulically-controlled, variable pitch propellers for engines producing up to 5,000 hp, and two-blade to four-blade electrically-controlled variable pitch propellers for engines producing up to 350 hp, as well as two-blade fixed pitch propellers. In addition to providing significant noise reduction, they have no life limitation and are repairable in case of damage from foreign object debris (FOD). MT-Propellers also provide the best vibration-damping characteristics for almost vibration-free propeller operation, and have bonded-on nickel alloy leading edges for superior erosion protection of the blades.

The company holds over 220 STCs worldwide and is an OEM supplier for more than 90 percent of the European aircraft industry, as well as 30 percent of the U.S. aircraft industry. The company has more than 28,000 propeller systems with more than 90,000 blades in service.
