The EAA builder package that everyone I know buys before doing an E-AB makes registration sound simple. Ha! Mine has been a combination of tear-jerking drama and situation comedy. I'll take the blame for initially attempting to register it in my name and signing it as a trustee, which the FAA assumed to mean a trustee of my wife's trust. Well, they bounced it, I revised it, they bounced it again, I called them and followed their advice before re-submitting, and it got bounced again. Geez. I had to provide the FAA with certified copies of our trusts, re-do a registration app, hire a title service in OKC to walk the papers over..... and 5 weeks later I get a very polite phone call from an FAA rep who asked for a fax number (remember those) to send my JUST APPROVED registration! In fairness to the FAA staff each and every person I've spoken with over the past few months has been great. Cheerful, helpful, and they go out of their way to help. Sadly they work for a very layered bureaucracy that limits what they can do, but I appreciated their efforts just the same. Bottom line, N907SB is a registered airplane. Now to finish it and get an AW cert to go with the registration. The adventure continues.
