Depends on what counts as "significant deferrment" and what counts as

Which begs this question.

How bad does a wood prop have to be to cancel a flight? I was going to
take a flight in a DA20 which has a twin blade Sensenich W69EK7-63 wood
propeller. On pre-flight, the prop was chipped in several places, no
runs but then its painted or enameled white.

The edges were so rough I was concerned about catching a splinter. I
passed.

And you?

I'm not a propellor sort of guy, but rough enough to catch a splinter
would be a definite no-go for me! Being that messed up sounds like a
potential structural problem to me. I'd bet that it's *probably* just
cosmetic, but I hate to bet on probablies. Having a blade suddenly fail
would ruin your whole day....
