How long is valid for?



An Airworthiness Review Certificate (ARC) is normally valid for 12 months from the date of issue. However, if the current ARC has not expired, provided the Airworthiness Review and recommendation were made within 90 days of the current ARC expiry date, the new expiry date will be 12 months from the previous expiry date and not the date of issue.
