There is a difference between the 51% rule and the requirements for a
repairman's certificate.  10 people can build an airplane as a group
and use their combined effort to meet the 51% rule (what ever that
51% is).  One and only one of the group can get the repairman's
certificate even if that person only did a small percentage of the
total work.

Yep, that's happens quite a bit and the DAR should point that out if the
builders happened to miss that. But if we're talking about buying a
restoration project or a 90% complete project, then some fancy time
accounting that needs to occur if someone other than the original builder
wants the repairman's cert.

I personally think that if you put several hundred or thousand hours into
working on all the major pieces of an airplane - original or restoration -
then you've got the pretty much an equivalent "education" and "building"
experience as the guy who started from scratch. Especially these days with
laser cut parts and match-drilled holes where you can snap an airplane
together in a weekend. (like Rusty :-)   If you had to make major repairs to
that type of kit plane you wouldn't necessarily have all the "education" and
experience to do that either.
