Anyone know how to drill a hole in an AN nut for safety wire?

N520TX said:Extending this argument further, why not make safetying of ALL AN fittings mandatory then ? Like from the fuel pump to the carb ? etc etc. When properly torqued, these fittings should never come loose.
szicree said:Regarding removing the cover, I've never tried it but I think either a heat gun or one of those big jumbo soldering irons that plumbers have might be very helpful.

jcoloccia said:Some will disagree with me, but once I put fuel in a tank, personally I wouldn't attack it with anything hot. Any welder can give you horror stories about "empty" tanks exploding as fuel vapors come seaping out.
I did the same thing. I added a dab of Proseal on the fitting after tightening it down during construction of the tanks. I did not have to rip out my inspection plate to do it since I was able to go back and look at pictures. I'm up to over 700 pictures, and worth it given the ability to go back and look at something like this.painless said:Being inexperienced, I thought it would be a good idea to smear.....you guessed it.....proseal over the fitting after tightening it down.
Needless to say, I'm leaving mine alone!

Well, I knew this but forgot. I called two IA's to verify. This is NOT an AD. Until it is, you don't have to do it. If you are sure these fittings are tight, don't worry about it, you don't have to stop and do this. This is just to cover their butt.

How am I supposed to be liable for something that the kit supplier hasn't sent me a notice about?

I wonder if the sloshing of fuel in the tanks "works" the pick-up and creates a chance that the otherwise bulletproof AN hardware will come loose.
Sam Buchanan said:I'm wondering if some sort of borescope could be used to inspect the fitting through the fuel sump hole?? Gotta be something in the medical field that would give us a view through that little hole.

Just curious - anyone know how the -10 is different such that this service note does not apply to them?N162RV said:Vans has just issued a service bulletin for all RVs except the -10 to comply with BEFORE next flight.
I would think a way of testing the integrity of the fitting might be to drain the tanks to about 5 gallons and do a volume test with the boost pump. If that looked OK, you could further test by draining the tanks, remove the line at the tank, attach a syphon hose to the tank fitting, add several gallons of fuel, and see if the fuel can be syphoned out. A loose fitting would allow air in the pickup tube fitting and break the syphon.
