Airworthiness Directive Management: What the CAMO Actually Has to Build
Airworthiness directive management is, on paper, the shortest obligation in continuing airworthiness. The rule that creates it is a single sentence. Everything that makes it hard is the process a CAMO has to build underneath that sentence, and the evidence it has to produce when someone comes looking.
The rule is one sentence long
Point M.A.303 of Annex I (Part-M) to Regulation (EU) No 1321/2014 says this, in full:
Any applicable airworthiness directive must be carried out within the requirements of that airworthiness directive, unless otherwise specified by the Agency.
That is the whole requirement. There is no prescribed workflow, no mandated software, no stated review interval. The regulation tells you the outcome and leaves the method entirely to you.
Which is precisely why airworthiness directive management goes wrong. A one-line rule invites the assumption that a one-line procedure will satisfy it. It will not, because three separate parts of the framework each come back and test whether the control is real.
Your CAME needs a dedicated AD section
The first test is structural. AMC1 CAMO.A.300 sets out the expected contents of the Continuing Airworthiness Management Exposition, and Part 1 — continuing airworthiness management procedures — lists as item 1.4:
Accomplishment and control of airworthiness directives
It sits alongside 1.2 (AMP development, amendment and approval), 1.3 (continuing airworthiness records) and 1.7 (repairs and modifications) as a procedure in its own right. Note the two words: accomplishment and control. Embodying the AD is only half of what the exposition is being asked to describe. The other half is how you know, at any moment, which ADs apply to which aircraft and what their status is.
If your exposition treats ADs inside a general maintenance planning section, you have a structural gap before anyone has looked at a single aircraft. Our guide on how to write a CAME covers how the rest of that exposition structure fits together.
What the procedure actually has to cover
Because the regulation prescribes no method, the burden of defining one falls on you. A procedure that survives contact with an audit generally has to answer five questions.
Where do ADs reach you, and how quickly
Name the sources you monitor and the frequency. ADs come from the State of Design authority and from EASA, and for a mixed fleet that can mean several publication streams. The question an auditor asks is not whether you receive them, but how long an AD can exist before your organisation knows about it.
Who decides applicability, and on what data
Applicability is an engineering judgement against effectivity: serial numbers, part numbers, modification standard, sometimes accumulated cycles. It depends on knowing your actual configuration. GM1 M.A.301 makes the link explicit, listing among the elements that define an individual aircraft’s configuration:
design-related requirements established in applicable ADs
The relationship runs in both directions. Configuration determines which ADs apply, and embodied ADs change the configuration. An organisation whose configuration control is weak cannot make reliable applicability decisions, and will not be able to demonstrate that it did.
How compliance dates are converted into planning
AD deadlines come in calendar time, flight hours, cycles, or at the next inspection of a given type. Each needs translating into something the planning system tracks and alerts on. The failure mode here is rarely ignorance of the AD; it is an AD that was assessed correctly, recorded correctly, and then quietly slid past its threshold because nothing was watching the right parameter.
How repetitive and superseded ADs are handled
A repetitive AD is not closed on first embodiment; it becomes a recurring task with its own interval. A superseded AD needs its replacement assessed from scratch, because revised effectivity may bring in aircraft the original never touched. Both are common audit findings precisely because both look finished when they are not.
What evidence is retained, and where
The AD status record and the evidence of accomplishment are different artefacts. The first tells you where you stand. The second proves how you got there, and it is the one that has to survive in the continuing airworthiness records for as long as the aircraft does.
The airworthiness review tests your AD control three ways
This is where AD management stops being an internal process and becomes something an independent reviewer examines. The AMC to point M.A.903 sets out what the documented review of aircraft records covers, and item (5) is airworthiness directives:
applicable ADs are properly recorded in accordance with AMC M.A.305(c)1;
applicable ADs and measures mandated by the competent authority in immediate reaction to a safety problem are not overdue; and
ADs have been properly complied with, if applicable, as evidenced by the corresponding maintenance release and, if feasible and appropriate, by physical confirmation on the aircraft.
Three distinct tests, and an organisation can pass one while failing another. The records can be immaculate while an AD is overdue. Nothing can be overdue while the evidence of accomplishment is missing. And the paperwork can be complete while the aircraft itself does not match it — which is what the physical confirmation is there to catch.
Worth noting too that the second bullet is not limited to ADs. It extends to measures mandated by the competent authority in immediate reaction to a safety problem, which may arrive through a different channel entirely and on a much shorter timescale.
And then it appears on the ARC recommendation
The third test is the statement the airworthiness review staff sign. The AMC requires that statement to confirm the aircraft in its current configuration complies with, among other things:
airworthiness directives up to the latest published issue
Up to the latest published issue is the operative phrase. Not up to the last review, and not up to whenever the AD list was last refreshed. Someone is putting their name to currency at the moment of signature, which means the AD status has to be genuinely live rather than periodically reconstructed.
Where it usually goes wrong
- The AD list is a spreadsheet nobody owns. It exists, it is broadly right, and no named role is accountable for its currency between reviews.
- Applicability is assessed once and never revisited. A modification embodied two years later changes the configuration, and nothing triggers a re-assessment of previously non-applicable ADs.
- Repetitive ADs close on first embodiment. The task is marked complete rather than converted into a recurring item with a tracked interval.
- Evidence lives with the maintenance organisation, not with you. The work was done correctly, but the CAMO cannot produce the maintenance release that proves it.
- The exposition describes a process the organisation does not run. The most common CAME failure of all, and AD control is a favourite place for it to surface.
The short version
M.A.303 gives you one sentence and total freedom of method. AMC1 CAMO.A.300 then requires you to write that method down as a named procedure. The airworthiness review checks it three ways, and the ARC recommendation puts a signature against its currency. The regulation is short; the control it expects is not.

Frequently asked questions
What does M.A.303 actually require?
Point M.A.303 of Annex I (Part-M) to Regulation (EU) No 1321/2014 states that any applicable airworthiness directive must be carried out within the requirements of that airworthiness directive, unless otherwise specified by the Agency. That single sentence is the whole rule. It prescribes no method, no software and no review interval, which means the organisation has to define and document its own process.
Does the CAME need a separate airworthiness directive procedure?
Yes. AMC1 CAMO.A.300 lists the expected contents of the Continuing Airworthiness Management Exposition, and item 1.4 of Part 1 is accomplishment and control of airworthiness directives. It is a named procedure in its own right, sitting alongside the aircraft maintenance programme, records, and repairs and modifications. Folding AD control into a general planning section leaves a structural gap in the exposition.
How does the airworthiness review check AD compliance?
The AMC to point M.A.903 sets out three separate tests during the documented review of records. Applicable ADs must be properly recorded in accordance with AMC M.A.305(c)1. Applicable ADs, and measures mandated by the competent authority in immediate reaction to a safety problem, must not be overdue. And ADs must have been properly complied with, as evidenced by the corresponding maintenance release and, where feasible and appropriate, by physical confirmation on the aircraft.
What happens to repetitive airworthiness directives?
A repetitive AD is not closed when it is first embodied. It becomes a recurring task with its own interval that has to be tracked like any other scheduled requirement. Marking it complete on first accomplishment is a common audit finding, because the task looks finished in the records while the obligation is still live.
Is AD management the CAMO’s responsibility or the maintenance organisation’s?
The CAMO manages it. The maintenance organisation carries out the work and issues the release, but assessing applicability, planning the compliance date, controlling the status and retaining the evidence sit with the organisation responsible for continuing airworthiness. A CAMO that cannot produce the maintenance release proving accomplishment has an evidence problem regardless of whether the work was done correctly.
