How long is a Second Class Medical certificate valid for individuals over 40?

The validity period for a Second Class Medical certificate for individuals over the age of 40 is indeed 12 calendar months. This regulation is established by the FAA's medical certification requirements, which specifically stipulate that pilots holding a Second Class Medical who are 40 years of age or older must renew their medical certificate annually to ensure ongoing compliance with health standards necessary for safe flight operations.

In contrast, pilots under 40 years of age can hold a Second Class Medical certificate for 24 calendar months, reflecting the FAA's consideration of the lower health risks generally associated with younger individuals. Understanding these age-related distinctions in certification duration is crucial for maintaining legal piloting status and ensuring flight safety.
