An aircraft's annual inspection was performed on July 12 this year. The next annual inspection will be due no later than which date?

• A. July 31, next year
• B. July 12, next year
• C. July 31, this year
• D. December 31, next year

Answer: (A)

Annual inspections must be completed within 12 calendar months, and the due date is the last day of the month that contains the 12th calendar month after the month of the last inspection. Since the inspection was done on July 12, counting calendar months forward places the 12th month as July of next year, and the last day of that month is July 31 next year. So the inspection must be completed no later than July 31 next year.

Choosing July 12 next year would be exactly 12 calendar months later, but the requirement is by the end of the month that ends the 12th month, not the same day. July 31 this year would be within the 12-month window, and December 31 next year would exceed the 12-month limit.
