My plane recently had a 500 hr mandatory prop inspection @ over $6k, three out of 4 blades failed. Total coast to repair was quoted at around $17K. New props quoted at around $30K. I chose to install new props. The new propellers (hartzell) comes with operation limitation . " avoid continuous use between 2000 and 2350 rpm, Thats most of the crossing range!! do you know of any other option for propellers for the 1960 travelair with lycoming o-360 ? My mechanic is running out of ideas.
