337 has nothing to do with EXP/Std reg changeover. It is the number of
the form that stands for "major repair or alteration" and is typically
accompanied by a new weight and balance when major repairs
(reattaching a tailboom for instance) or alterations (like winglets),
although may not be necessarily in every case.

My SZD59 is EXP reg, but I still went the 337 route when I modded my
stock mechanical brakes to a hydraulic Cleveland setup. Didn't need
the w&b for this job, since the part total was within 1.5lbs of the
old setup and that is all predominantly on CofG, but I didn't trust my
old one and wanted to put some weight in the tail, so a fresh w&b was
useful to me to determine how much...

And why exactly do you want to keep the std reg? Do you use it in a
commercial capacity? (obviously not since it has 1 seat...) Exp rating
allows you a lot more leeway with *legally getting your ship/cockpit
dialed in etc. Work that falls somewhere between changing a tire and
needing a 337 still needs to be signed off by an A&P, but a 337 needs
an A&I and is much more involved. Std means anything beyond changing a
tire/simple maintenance level work has to be farmed out to an A&P,
regardless of your skills.

Actually, I am not the one who started the thread about going into the
experimental category. *The reason "I" would stay in the standard
category is to avoid any restrictions that may come with the
experimental category, such as for exhibition only, etc. *I'm pretty
sure going to experimental would place various restrictions on the
flying of the aircraft. *Also, going to an experimental certificate
won't eliminate the need for A&P inspections/sign offs. *As far as I
know, only people with repairman certificates can sign off work on an
experimental "AMATEUR BUILT" aircraft and then only if they built a
majority of the aircraft. *Just putting winglets on a certified bird
would not be a basis to get a repairman's certificate...- Hide quoted text -

Scott,
Any A&P can annual an Experimental or Experimental Exhibition
aircraft.
This is a lot easier formany people.
