Plain English Meaning

Something the AD requires you to do again and again on a set schedule, not just once.

Full Definition

In the context of an Airworthiness Directive (AD), a recurrent action is a required inspection, check, or task that must be repeated at specified intervals — such as every set number of flight hours, cycles, or calendar months — for as long as the AD remains in effect on the aircraft.

Context Anchor

You see this when reviewing an airworthiness directive or an aircraft’s maintenance records to confirm whether a required task has to be repeated.

Derivation

Recurrent comes from the Latin recurrere, meaning 'to run back' or 'return.' It describes something that keeps coming back around — in this case, a required action that returns on a set schedule rather than being completed once and finished.

Why Pilots Care

Failing to complete recurrent actions can result in an unairworthy aircraft, grounding, or safety risks.
