Posted 9 Nov 2018 (edited) hi everyone just wondering, would anyone use this prop on a 582/532 and feel safe? Wanting to fly family and friends . Its a 66" type f powerfin.. is it worth sending to powerfin for repair? This is the only crack i can find but paint is worn on both edges of both blades.

Posted 9 Nov 2018 Better safe than sorry... Unless you can send up your mother-in-law as test pilot I would send the blade to Power Fin for verification. 1 person likes this Share this post Link to post Share on other sites

Posted 12 Nov 2018 Hell no!! A loss of a blade could be the last flight of your (and whoever you have with you) life. A lost blade can literally tear the engine off the front of the plane.Send that thing to Powerfin. Sometimes if a blade is non-repairable they will work with you on a replacement.Always air on the safe side. It's dangerous enough as it is. Share this post Link to post Share on other sites
Posted 12 Nov 2018 Only the manufacturer should buy off on those cracks or repairs of them. Those cracks are not primary airworthiness - strength issues, they are trailing edge splits where the drag forces on the blades at high pitch cause a buckling of that area as the blade is bent aftward, so they split open. It seems that few broken fibers are there. I bet a simple repair and rebalance is the fix, but the manufacturer must be the source of this info.Send those pics to them and ask. 2 people like this Share this post Link to post Share on other sites

One simple and cheap thing that could save you when the unbalanced prop ripps the engine mount is a safety cable connecting the engine to the airframe behind the firewall.
