For a pilot under 40, when does the validity of a third-class medical certificate expire?

A third-class medical certificate for a pilot under 40 years of age is valid for a total of 60 calendar months after the date of the examination. This means that as long as there are no disqualifying factors that arise during that period, the certificate remains valid, allowing the pilot to exercise their privileges.

For pilots under 40, the duration of the certificate's validity is extended compared to older pilots, who typically have shorter validity periods for their medical certificates. This rule is designed to balance the risk factors associated with aging and medical conditions as pilots get older. Understanding the duration of medical certificates is crucial for maintaining compliance and ensuring safe operation of the aircraft.
