However I have been a lurker for quite some time. I have finished a 701 with the 912S and just got the FAA "pink" slip. I was wondering what distance from the Datum line to the center of the wheel are you guys seeing on the 701? I have 695mm and was wondering if thats in the ball park of you finished builders.

The test flying of any airplane is something great, Guys that dont care for aviation dont know what they are missing... Saludos Gary Gower do not archive.

SO IF, there is no air coming out of the perfect sealed tank, inflation at the given time will be the about the same, for our test. If it is really deflated then reinflate (lungs preassure) and check with soapy water. At late and colder night, we should be worried and looking at the "inflation" of another one, in a diferent place :-) :-) Sorry for the joke, please do not archive.. Saludos Gary Gower.

Frankly, it is possible because of the viscosity of mo-gas all the way up to 100 octane which is so small compared to other fluids, that a tank could have a weak seal that would seep gasoline that water, nor diesel would show or air to be noticeable. Consider this scenario: you have tested a tank, thinking it fine because of a flawed test, installed, front nose skin riveted closed, painted wing, wired and mounted on the fuselage when the first time you put high octane fuel in the tank and you start smelling the fumes?? What would that cost in time, effort and money to you as the builder? The prudent builder should want to test any subsystem as close to actual use as possible before assembly. FWIW, Best of luck, Bill ________________________________ Message 8 _____________________________________ Time: 03:23:11 PM PST US Subject: Re: Zenith-List: Fuel tank testing From: clamav-milter version 0.80j on hathor --> Zenith-List message posted by: Well, been there, done that... In fact did it today...for the second time. You have no idea how emotionally hard it is to take a drill bit to your wing...TWICE!!! The first time I opened up the wing was to fix a stuck mechanical transducer bob. The second time was to fix the damXXX????XXX! leak around the transducer fitting in the side of the tank. And yes, we did check the tank for leakage before re-installing it back in the wing. Actually, it was a good thing I opened the wing the second time. I also found that the new fuel line had split just beyond the hose clamp attaching the fuel line to the ferrule coming out of the tank. I'm thanking my luck stars I have a local fellow builder (601 XL, Corvair)who was gracious enough to lend me rivets, rivet dies, and a shoulder to cry on...TWICE!!!
