Yes, FAA certifications have expiration dates. For most pilot certificates, you must renew them periodically. For example, a Private Pilot Certificate does not expire, but you need to meet specific requirements, like completing a flight review every 24 months. Medical certificates have expiration dates based on the class (First, Second, or Third), usually ranging from one to five years, depending on your age and health. Similarly, other certifications, like Flight Instructor Certificates or Commercial Pilot Certificates, have specific renewal requirements, including additional training and flight hours.
