In which year pattern does the IA expiration follow?

• A. It expires on March 31 of odd-numbered year.
• B. It expires on March 31 of even-numbered year.
• C. It never expires.
• D. It expires December 31 of the year.

Answer: (A)

IA validity runs for two years and ends on March 31 of odd-numbered years. This fixed calendar pattern is set by FAA regulations, giving every IA a predictable renewal date regardless of when the authorization was issued. It ensures a uniform two-year cycle for meeting renewal requirements. The other patterns—March 31 on even-numbered years, December 31, or never expiring—do not apply because they would disrupt the standard renewal window or remove expiration altogether.
