I agree. On one of Van's promotional videotapes, there's a comment that
one guy built "3 RV-3s and yes, an RV-4." Did the second and third
RV-3s not cert airworthiness certificates?

Actually, jst to keep the record straight, you CAN buy an X-AB airplane.
But the biulder can not build and register another of the same kind.


Really? Where did you get that information? Do you know of a case where a
builder was denied the second airplane's airworthiness permit?
