Thanks for the many responses about my missing fuel problem.
For Bruce: After an early failure of the main fuel drain on a freezing cold morning while in Texas on business (just as Lyle Powell had once written would happen), I now prophylactically replace the o-ring fittings in the drain every 3 to 4 years or so. They always come out with cracks starting. (The early failure was due to a sliver of fiberglass jamming the drain. That was around the first 100 hours or so.) The current drains seem tight. Was at all of them yesterday.
For Robin: While I always griped about how long it was taking us to build, all things work together for good... for some. We got the SB in time about coating the heads of the bolts with lots of glass and resin to minimize leaking. (As I write this, I think we got the SB after the bolts were in, but before the wing was closed. I think you were supposed to dip the bolts in resin while inserting. We didn't do that, but did glass over the heads.) But I forgot that was a classic failure point, so I'll plan to look there too.
For James: Yeah, I'm hoping the blue stain will be obvious. We have an Emergency Gravity feed that's fed by a ball valve. We had some leaking with a fitting there at about 500 hours. (I could smell it back then.) It wasn't much of a blue stain, and it's gone now, but I've seen it before, so know what to look for in the wing. Nothing seen on the hangar floor.
I'm hoping the leak isn't in the middle bay. Should have more data after Saturday evening.
