How long is a Certificate of Registration valid?

A Certificate of Registration for an aircraft is valid as long as the ownership and address of the registered owner remain unchanged. This means that as long as the same individual or entity owns the aircraft and the address on record is current and accurate, the registration remains valid.

If ownership of the aircraft is transferred or if the address changes, the certificate must be updated with the appropriate authorities to reflect these changes. This is important for maintaining legal compliance and ensuring that the aircraft is properly registered with the Federal Aviation Administration (FAA) or the appropriate aviation authority.

The other options are not accurate portrayals of the validity period of a Certificate of Registration. For instance, it does not expire after a fixed timeframe like one year, nor is it valid indefinitely without conditions. Furthermore, while the registration does become invalid upon the sale of the aircraft, it is not valid only until that point if ownership and address remain unaltered.
