If an aircraft's annual condition inspection was performed on July 12, this year, by what date is the next annual inspection due no later than?

• A. July 31, next year
• B. January 1, next year
• C. December 31, next year
• D. July 12, next year

Answer: (A)

Annual inspections are required every 12 calendar months, with the deadline being the end of the month that marks the 12-month anniversary. Since the last inspection was done in July, the 12-month period runs from August this year through July of next year. The last day of that ending month is July 31 next year, so the inspection must be completed by that date to be in compliance. Dates earlier than that are acceptable, but July 31 next year is the latest allowable due date.
