The propeller is an 80-inch diameter constant-speed unit that features three
Kevlar/epoxy blades in an aluminum hub. The spinner is fabricated from
aluminum alloy. A more detailed description is found in Hartzell Manual 145
(Propeller Owners Manual).
Electrically heated de-ice boots may be fitted to the propeller blades. To protect
the composite blades from overheating when the propeller is not turning, the
propeller de-ice system is de-activated via a weight-on-wheels switch. A push-
to-test switch is provided to test the propeller de-ice on the ground. Use of the
test switch is limited to 10 seconds.
