I'm New Here
Hey guys,
So I've been dealing with this issue for quite a while. I finally got my RV-10 flying a couple months ago with a fun set of issues that I have to deal with on a daily basis. I've finally been narrowing things down but theres one that no matter what I do the problem persists.
A few flights ago after I landed, there was smoke in the cockpit. It was most definitely (at least at the time) determined to be electrical smoke. No fire came of it. I shut off the batteries and taxied to the hangar. The smoke went away and I started to look for anything that would be causing the issue.
Long story short, I've pulled apart the center tunnel (A pain in the *** in my plane), the side panels, under the seats, and even the baggage bulkhead to find the source of the smoke. Just today I left my high suspect access panels off as well as my autopilot panel (GNC 307 sits right above my circuit breakers/bus bar and can see where I was originally suspect of the bus bar coming into contact with the carbon fiber).
I went and flew, and nothing. The smell was still there, but the smoke wasn't very apparent. Its driving me crazy. So I called Aerotronics, my avionics dealer, and asked them for some troubleshooting tips. Obviously my airplane is my airplane and I'm the only one who knows exactly where every wire run is but I needed some other opinions. After an hour or so troubleshooting and this flight, my avionics guy suggested the possibility it wasn't electrical. He suggested the possibility that the electric fuel boost pump was getting hot enough if I left it on too long that it could be burning off the preservative oil that it came in the bag with.
I couldn't see anyone else in a search having smoke or smells due to this issue. The thing that baffles me is I ONLY ever see smoke when I land the plane (fuel pump on). And in flight the smoke would escape through any holes in the plane it can fly due to low pressure outside.
Anyway, I think thats most of the essential information I can give.
Anyone else have this (the fuel pump burning preservative oil off) issue?
I hate that I cant definitively find the issue and know what it is.
Thanks in advance
Blake
