Jay forgot to send it on to Steven, Chris, and Michael, and sent it back to me instead. So it will be on it's way again by this afternoon. There are just enough inserts left for this trip.

I ordered a replacement and when it arrives I'll compare it dimensionally to the faulty one. I tried a new o-ring but it leaked just as bad. There's no evidence of significant scoring or marks in the bore, so I guess the bore is just worn too large. We'll see when the new one comes in. I think the Viton o-rings and MIL-PRF-83282D are the way to go.

I few back to KUES that evening and found a leaking right caliper. Opened it up and found the o-ring pretty worn on one side, almost flat. The wall looked good with no sign of scoring or scratches. I replaced the o-ring but have not tested the brakes yet. I also found the left caliper leaking slightly as well. Have not inspected it yet. The plane has about 170 hours.

When I removed them from the old RV-8 fuselage, I must have put them in a very "safe" place and now I can't find them anywhere. Guess they're pretty safe.

We also treat the skin agains corrosion (Alodine), then Fillet seal the antenna flange to the skin for water-tight integrity. The biggest failure is returning the aircraft to service too soon, pressurizing the cabin for passengers and getting blow-outs in the fillet which allows moisture. The corrosion is certain in the presence of millivolts, moisture and dissemilar materials.

Recall that the antenna needs an RF ground, not necessarily a DC ground. Us ing the gasket mitigates the corrosion aspects while still providing the nee ded RF ground.
