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.
