Recently got my updated registration certificate for the new 7-year change. My previous certificate was signed by the FAA administrator but the new one has no signature - it has a signature block but it’s empty. 91.203 requires an “effective” registration certificate - it doesn’t specifically say that it must be signed by the FAA administrator. So I’m thinking I’m in compliance, but curious if others have views or have looked into this? I emailed the FAA directly (probably dumb, I know) and did not receive a response. Appreciate any thoughts here.
