Hartzell Propeller introduced its own line of de-ice components to support the entire line of Hartzell propellers. Hartzell is marketing its new components as replacements for third-party manufactured parts, including boots, wire harnesses and slip rings. Hartzell boot replacements are under warranty until 18 months or 2,000 flight hours. Other de-ice components are covered for 12 months or 1,000 flight hours. “The key difference from other suppliers is that the Hartzell warranty also covers labor to remove and replace defective parts,” the company said.
