Apparently the wrong type of thread lock (permatex) was used by the overhaul shop, that assembled it last winter. All of the pin base bolts had lost torque, and the failure occuured as a result of loose bolts on the pin base that failed. The prop is being repaired and the proper thread lock (locktite) is being used. I had noticed one blade seemed a little looser over the last few weeks and had planned to have it looked at by the prop shop on the way to my next show....didn't make it that long :) I would suggest checking the blades by twisting them in pitch and have any looseness inspected. The bottom line is that this was an error in reasssembly by a prop shop and not a problem with the propeller design... Thanks to all who called and wrote...
