cruises five kts faster with the five-blade Hartzell
propeller, climbs to a cruise altitude of 28,000 ft
10 percent quicker and has a 50-foot reduction in
total takeoff distance. Its highly swept airfoil
reduces flyover and cabin noise and its blades are
certified for unlimited life.

grade carbon fiber and is five to 10 times stronger
than beech and spruce wood core propellers. Stronger
materials permit thinner, wider airfoils that
state of the art wedge shank retention system made
of stainless steel alloy is more robust than
alternative lag bolt and aluminum construction.
Further, it has a nickel cobalt leading edge with a
stainless steel mesh erosion screen for unmatched
durability and FOD protection.
