What could happen if a pilot does not notify the FAA of an address change within the required timeframe?

If a pilot fails to notify the FAA of an address change within the specified timeframe, they may face fines and penalties. Regulatory authorities require pilots to keep their contact information updated to ensure that important communications, such as renewals, notices of violations, or other critical messages, reach them in a timely manner. The lack of timely notification can be viewed as a failure to comply with FAA regulations, leading to potential fines or other administrative penalties as a means to enforce compliance.

The other options do not reflect the actual consequences of failing to notify the FAA. Continuing to fly without consequence is not viable since regulatory compliance is a fundamental aspect of aviation safety and governance. Being automatically grounded or losing a license would involve more severe infractions than simply not updating an address; those outcomes typically arise from serious violations or safety issues, rather than administrative lapses.
