How do you gauge if a scratch is too deep? My HS skin seems to have come with
a scratch in it that is about 2 inches long. I might be able to sand it out
but it would probably take something as course as 120 grit for how deep it is.
and then more fine to polish it. Would this be acceptable for structural
reasons? I can put it on the bottom and I'm sure the paint would cover it as
well but I don't want to chance it if it is a safety issue.
Also...uh oh, here we go.... is it a big deal not to prime the inside of the
skins even though I've taken the time to prime all ribs and spars?
Thanks,

Well, I had my first engine failure and landed without incident. I need some
help trouble shooting this one. On takeoff at FPR, at about 800 AGL, the
engine lost most of its power. It was a sputter, followed my an almost shut
down. It reminded me of the time I was setting up my fuel flow on the RMI
and ran a tank try. I check the boost, it was confirmed on, mixture rich,
and switch tanks. No luck. I jockeyed the throttle and mixture on the down
wind, just to see if I could get more power and still no luck. I landed rwy
32 with no problems and after a few sputters to taxi clear, the engine
completely shut down on the runway. I tried to restart on the ramp and the 3
year old battery also decided to quit.
My plane is normally hangared, right now I'm doing my CFI at Aviator and the
4 has been left out for a week with half tanks. I thought it might had been
fuel contamination or moisture, but the full cup samples I took after the
long push to the ramp showed no problems with the fuel. No samples were
inspected prior to the flight. It took about a minute to land and I was
thinking that if it were water in the line it would have cleared and fired
back up, but I've also heard that fuel injectors are more sensitive to water.
Where to start, first thing tomorrow, after I order a new battery, I'll pull
the filters and purge the system, but other than that I don't know what it
could be. My system is an 0360, Bendix injector, and airflow performance
boost/filter setup. I do have the RMI fuel flow transducer between the
injector and flowdivider/spider. If anyone has any ideal where else I could
look, please advise.
Thanks,
Carey Mills
