For a first-class medical certificate issued to a 23-year-old pilot on October 21, this year, when will it expire?

• A. October 31, 5 years later
• B. October 31, 1 year later
• C. October 21, 5 years later
• D. November 30, 5 years later

Answer: (A)

First-class medical for a pilot under 40 is valid for five calendar years. The expiration date is the last day of the month in which the 60th month after issuance ends. Since the certificate was issued in October, the 60th month ends in October, so the expiration is October 31, five years after issuance. Therefore, if issued October 21 this year, it expires October 31 five years later.
