I'm trying to buy an experimental airplane that may have an issue on the FAA registration... the builder listed on the original registration, himself and his (now-ex) wife as co-builders in the format of "LASTNAME INITIAL/LASTNAME INITIAL" (e.g. "SMITH A/SMITH B") but the AW cert and ops limits doc shows simply "LASTNAME" as the builder (e.g. "SMITH"). The FAA accepted these items this way and the airplane has been on record with them and flying for nearly ten years. I've been told by other folks that the builder's name must match perfectly, exactly the same text strings, on all the docs (reg, aw cert, op limits, and data plate), or the airplane is "paperwork-unairworthy". Is this true? If so, then how does this get fixed?
The owner/builder just went thru the process of getting his builders name spelling corrected on the registration, as it was misspelled in the manufacturer's name field on the registration by one letter in both last names (e.g. like "SMATH A/SMATH B"), and was that way for almost ten years. That part has now been corrected, but it was quite a big hassle since he had to locate his ex-wife in another state and get her notarized signature on a form and he's reluctant to repeat the process even if the FAA will allow further amending of the "manufacturer's name" to shorten it to simply "LASTNAME" to match the rest of the docs. I'd really like to buy this particular airplane because it's one of the best built ones I've ever seen, and I'd hate to have to walk away from it.
