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....

That would be a pass for me! I would stop right there......

For a friend here.... he passed on 3 spinner cracks on a rental 172.

One crack was 1 1/2 in long.

They (others) continued to fly the aircraft for another week before
the spinner was removed

Thanks, guys, I was really shocked as the local CFI had no problemo with
this prop which was on a student trainer.
