Are there any good arguments out there based in science and fact and not old
wives tales to support only doing a run up and prop check on the first
flight of the day ? I'm talking about a situation where you're flying
multiple flights a day and the engine never completely cools off.

Well I never was one for science - more toward the arts personally so I
can't base anything on science for you.

What I can tell you is that last year our club was flying young eagles
and they decided that to save time we would only runup for the first
flight. I refused and actually took a lot of criticism for my refusal.

2nd flight - I'm the only one to runup - no left mag.
Plane parked - later the mag was removed and was found to be totally
dead as it had managed to internally disintegrate itself.

Should I have done the runup? Everyone else said no.
I would have been carrying 9 year olds over lakes and mountains.

2 years ago - 3rd runup of the day - another no mag day - parked.

So my unscientific opinion is that I don't fly unless I pass a full and
thorough runup, and if that p*sses somebody off - that's ok.
Because all of my flying is over lakes and mountains - and I don't fly
floats! So I check - and check again. If the checks don't meet my
standards I stay on the ground.
