I bought a 3-blade composite prop from Catto Props for my RV-9A. I've got about 190 hours on the prop now. Doing my inspection recently I took note of the chipping of the material along the leading edges of the blades. I'm attaching a photograph. I'm writing to ask whether this is still within the tolerance of normal wear and tear? Should I do anything to sand the edge of the prop? Should I put any kind of leading-edge protector tape on to prevent further damage?
