How long is a second-class FAA medical certificate valid, and how often must it be renewed?

A second-class FAA medical certificate is valid for second-class privileges for the remainder of the month in which it was issued, plus 12 calendar months – not two years. For example, an examination completed in January 2026 should remain valid through January 31, 2027. Air traffic controllers must maintain a Class II medical, and renewal is generally an annual career requirement. Review the FAA’s medical-certificate validity guidance for additional information.
