Propeller Off 2 (January 2021)

Our Hartzell propeller was sent to the Prop Shop and unfortunately was found to have corrosion on the hub. This was not repairable as no machining is permitted on this component. A replacement hub would have to be specially made by Hartzell and would cost an awful lot of money. A new 2 blade Hartzell propeller which would fit and work perfectly was also not an option as the new model had an alluninium hub, a different serial number and hence no approval for the Bölkow 207.
