I saw this post earlier, before any one responded, but couldn't think of an unsarcastic way of saying just what others have already said.

Failures most often happen during a change of status. That is to say, when going from not running to running and from idle to any other power setting. I'm speaking in very general terms here. That means that this prop will never ever fail as long as you dont start the engine. BUT if you do start it then it might fail in the start up process. Do you want to be right next to it if it goes? If it doesn't fail on start up then it will likely fail when you are messing around with the throttle. Do you use throttle when you fly?? every time you do, you risk failure. If it fails in flight during throttle transition, would this prop maintain proper balance with an inch missing from one blade??? If not then what possible effect could that have on the airframe. Does your plane as a whole cost more or less than the prop alone?

The real question isn't whether or not it CAN be fixed but SHOULD it be. answer those above questions honestly then you tell us whether YOU think it SHOULD be done.
