Okay, guys, yes, I hit wrong key and didn't catch it as I checked my post. Wrong code. Good catch.
Please, I am not disputing Lawrence. And as I stated, it was years ago, I know they gave me some paperwork, which could easily have been just a QC program. I indicated that in my last post. The inspector, could easily have been in house QC and making sure everything was up to par for FAA audits or whatever. The guy who was my contact told me everything had to be checked and approved by this other guy, whatever his title was, and he had to answer to the FAA. That's all I can remember.
EDIT: please note first post, I said, an FAA regulation of some kind. I still stand by that. If the institution had to have a QC program audited by the FAA, then it was an inspection brought about by FAA requirements, was it not? I'm asking. And this is what I believed from info supplied me by the customer, right or wrong.
Also, forget who said it, we had nothing to do with the frame. We were repairing the neck connection into the fuel tank. Also, occassionally, rub through holes where the straps holding the tanks would cause them to leak. Nothing structural. Just sealed the tanks back up.
Now, to the reason I even said anything in the first place. The OP had asked if there were any aviation codes. He was referred to Aerospace Codes which I responded I didn't think were the correct direction to look. (Though they wouldn't hurt to have in such a case.) I think that if I understand Lawrence correctly, my general direction was correct. Aviation and Aerospace are not one and the same. Different animals. And, it appears, welding upon airplanes is a very lax environment in many ways.
Not now, nor ever, especially in this thread, trying to pass myself off as an expert in this area. And especially was not in any way trying to contradict Lawrence. Please read my previous two posts carefully if you doubt this. I respect Lawrence, and you Henry, very much in these areas. No one else had put up any info and I just shared my personal experience which may be somewhat muddled in memory because of the time span. And, as I said, I cannot find any of that paperwork, way too far back for my records to be easily accessible.
So, I for one picked up some things of interest here. I hope that especially Lawrence's input answered the OP's question. If I muddied the waters, I apologize. Just trying to make sure the question was properly answered, and I did not think Aerospace was the way to send him.
Have a Merry Christmas and a Happy New Year.
Have a Great Day, Brent
Two of My close friends are A&P mechanics, one for American Airlines , the other for a govt. contractor. While they both know a whole lot about the machines they service, I don't think You would want to fly in a brand new untested homebuilt knowing THEY were the only ones who inspected the thing.
You are right, they only learned a little bit about welding at the A&P school, and it was a good one. One of the guys I mentioned is a pretty good amature welder, but He didn't learn it at A&P school.
