Found a 1/16” nick during preflight. First one in over 500 hrs on this prop. It’s well within the specs for field dressing per 20-37E.
Tempted to just do the field overhaul with my AP, but I don’t want to end up with an unbalanced prop. Was hoping to hear some other perspectives. My AP normally works on a rental fleet.
As an aside recommendation from AP was to use small rat tail file to smooth out the nick, getting just below the surface of the impact. Then take a few passes with a fine flat file down the leading edge of both blades to smooth out each blade. Was clear that we need to maintain the airfoil on both sides. After that bend it the nick using the 5x guidance on each side. He said normally small nicks like this get partially worked in by the long passes on the blade. Finally sand the leading edges before prime and touch up paint.
