Gubni Posted May 2, 2021 Report Posted May 2, 2021 I'd like to keep the discussion about the prop only please. One blade has a bend. See attached picture. Should I buy a new prop, refurbished prop, or have this one fixed? What company should I ask for help? Quote
kerry Posted May 2, 2021 Report Posted May 2, 2021 What blades do you have? Some are hard to come by. Quote

Rwsavory Posted May 2, 2021 Report Posted May 2, 2021 Might be repairable. Cody Stallings is the guy to talk to. @Cody Stallings 2 Quote
Guest Posted May 2, 2021 Report Posted May 2, 2021 From the type certificate, you can not reduce the blade length, or prop diameter. Quote
Bartman Posted May 2, 2021 Report Posted May 2, 2021 I wouldn’t worry about that. I’ll buff right out with some polishing compound. Quote

Or just even it out by taking sheet metal pliers to the other blade. Kick it old school with the Q-tip design. Being serious best option would be to buy one new blade and iran or overhaul the prop. Not many people upgrade from that prop, new might be your only option. Quote
Hank Posted May 2, 2021 Report Posted May 2, 2021 Can a blade be hit hard enough to bend without requiring engine teardown & inspection? Quote

However, that blade isn’t looking good without Reduction in diameter. I know where a set of those blades are at Overhauled with no Mooney to call home. Quote

Guest Posted May 2, 2021 Report Posted May 2, 2021 The same blade set is used in the McCauley propeller on a J model which is allowed to be shortened, so your blade may have some remaining value. Clarence Quote

MSer’s prop guy... Known to have and share all the details required for good prop decisions... Owns an M20K Rocket... When it comes to mangled pieces of prop... I went with something completely different... I couldn’t tell where the damage ended, and the good prop began... and if a metallurgist would be needed... MS has a metallurgist... There are such great forces on the prop... and the slightest imbalance can have disastrous results... as in losing parts of the prop can be really bad. Make sure you get the right shape for the airfoil... the whole length of the blades... People dynamically balance their props for the near perfect balance... They dress out any bumps and nicks for near perfect strength... See if there is a way to let these blades go... to somebody with much shorter blade requirements... Pp thoughts only, not a mechanic...
