The frequency of FAA flight physicals depends on the class of medical certificate you hold and your age. For a First-Class medical (required for airline transport pilots), those under age 40 must renew every 12 months, while those 40 and older must renew every 6 months. A Second-Class medical (required for commercial pilots) has a mandatory 12-month renewal period regardless of age. For a Third-Class medical (used by private and student pilots), the certificate is valid for 60 months (5 years) if you are under age 40 at the time of the exam, and 24 months (2 years) if you are 40 or older. In 2026, these regulations remain strictly enforced to ensure the ongoing health and safety of the national airspace. It is also worth noting that under BasicMed, which is an alternative for many private pilots, you must complete a medical education course every 24 months and visit a state-licensed physician for a physical exam at least every 48 months. Always check the "expiration" date printed on your current certificate, as the validity period is calculated to the last day of the month in which the exam was performed.
