Definition
In the context of Airworthiness Directives (ADs), a recurrent or continuing action is a required inspection, check, or maintenance task that must be performed repeatedly at specified intervals — such as every flight hour, calendar period, or operating cycle — rather than as a one-time fix. The compliance obligation does not end after the first action; it continues for the life of the aircraft or until the AD is superseded or terminated.
Plain English
It's an AD requirement that has to be done over and over on a set schedule, not just once. You complete it, then keep doing it again at the stated interval for as long as you own and operate the aircraft.
Context Anchor
Seen when reading an Airworthiness Directive to determine whether its requirements are one-time only or must be tracked over time.
Derivation
‘Recurrent’ comes from Latin recurrere, meaning ‘to run back’ or ‘happen again.’ ‘Continuing’ simply means ongoing. Together they signal that the action keeps coming back around — it doesn’t close out after one completion.
Why Pilots Care
Determines whether an aircraft can legally continue operating; missing a required recurrent action violates the AD and can result in grounding.
Intuition Check
Do not assume “action” means one task done once. In this context, the action may need to be repeated on a schedule or kept in effect continuously.
Example Sentence 1
The AD on the fuel selector valve was a recurrent or continuing action, requiring inspection every 100 hours of flight time.
Example Sentence 2
Because the directive calls for recurrent or continuing action, the owner scheduled the next inspection before the due date.
