If a third class medical certificate was issued to a 35-year-old pilot on March 26, when will it expire?

The expiration of a third-class medical certificate for a pilot is determined by the age of the pilot at the time the certificate is issued. For pilots under the age of 40, a third-class medical certificate is valid for 60 months (or 5 years) from the date of the examination. Therefore, since the pilot in question is 35 years old at the time of issuance on March 26, the certificate will expire 5 years later, landing on March 31 of that fifth year. The specific date is rounded to the end of the month in which the medical examination was performed.

In this case, if the certificate was issued on March 26, it remains valid until March 31, five years later, making that the correct answer. Understanding this rule is crucial for pilots to ensure they maintain valid medical certification to operate an aircraft legally.
