Geez, I'm surprised my wings haven't fallen off (countersunk wing rivets under the wink walk) by the time I've run out of gas!!
I was pretty anal about measuring the fuel. On my tank with the airplane level, the right most sight glass circles equal even gallons. So my sticker is placed correctly.
However, I will double check it the next time I get the fuel down that low. I may have made a mistake. I would never take off with the fuel that low in any event but it needs to accurately reflect the proper fuel level in the tank so thanks for pointing this out. I had two of them made at the vinyl shop so it's an easy thing to peel this one off and install the other one.
Sorry Randy, I didn't mean to induce defensiveness or sarcasm.
It is actually an important detail, which is why it was well documented in earlier plans pages when the sight window was being used. Early Section 51 pages have a detail that shows where the label should be located, and I think the PAP may have also specified to fill the tank with 4 gallons and place the label accordingly.
If you installed it using that technique, then I guess you are fine.... but it looks lower than any I have seen. So, my post was in the interest of the safety of a fellow RV-12 pilot. This is after all just an internet forum.... you can take it or just ignore it.... your choice.
As for the wing walk comment, that is kind of a cheap shot.
I am so tired of people justifying mods that they have done, by saying their airplane hasn't come apart yet so how can it be a problem?
To put it bluntly, that is about the lamest response anyone could ever give.
Lets suppose someone does a mod to their aerobatic RV that does actually reduce the usable wing strength from 6 g's to 3.5, and then they fly for 10 years never exceeding 2.5 G's.
Because of that history, they proclaim to the entire world how great of an idea they invented and that everyone should do it to. But no one (even the designer/innovator) knows the truth. Is that a good situation? Is that person being responsible?
I did not say your wings are going to fall off. It would require some serious analysis and testing to say that.
What I
do know, is that what you did went against accepted industry standards for aircraft construction. It is not possible for you to machine counter sink holes in the wing walk area on an RV-12 wing for 1/8" rivets, and not have compromised the strength to some degree, unless you replaced the wing walk doubler with one made from material at least .050 thick. How much it has been compromised is anybody's guess (unless someone chose to do some FEA analysis and static testing, to find out).
