FAA Registry

Would anyone find it strange to see a RV on the FAA registry with a Mfg yr newer than the certificate issue date?

MFR Year 2010
Certificate Issue Date 08/25/2005

I've looked at may other tail numbers and never seen the dates flipped like that.

Is this something of concern?
Would this become a problem during transfer of ownership?

The "Certificate Issue Date" is for the registration certificate, not the airworthiness certificate. Look lower on the record for the "Airworthiness date" to see when the airworthiness certificate was issued. The original registration certificate issued to the builder can be months or years before the airworthiness date. But if a new entity takes ownership, that date will show up in the "Certificate issue date", so once an aircraft changes hands, it won't have the earliest date in the "Certificate Issue Date" anymore.

It's not all that uncommon on homebuilt aircraft for the registration certificate to be originally issued well before the airworthiness date. (It's the airworthiness issuance that sets the manufacture date, not the registration.)

That explains it, thank you.
