To determine the expiration date of the last annual aircraft inspection, a person should refer to which record?

• A. Aircraft maintenance records
• B. Logbook
• C. Airworthiness certificate
• D. Owner's manual

Answer: (A)

Maintenance records document the complete history of required inspections, including the most recent annual and when its 12‑month interval ends. To determine the expiration date, you locate the date of the last annual inspection in those records and count 12 calendar months from that date. The airworthiness certificate shows that the aircraft is currently airworthy, but it does not provide the inspection’s due date. The owner’s manual covers operation and maintenance schedules in general, not the actual history. The logbook may contain an entry for the annual, but the official, consolidated record for determining the expiration is the aircraft maintenance records.
