CAMO is not an FAA term. It is European, defined within the EASA framework as an organisational approval for continuing airworthiness management, with named post-holders and a scope of work set out in an exposition.
That single fact causes a surprising amount of confusion, and a genuine amount of duplicated work.
The same job, described two different ways
US operators absolutely perform continuing airworthiness management. Somebody decides what maintenance is required and when, assesses every airworthiness directive against the fleet, keeps the programme current, controls the records and produces the evidence. The function is not optional and the standard is not lower.
What differs is the architecture of the requirement. The EASA framework packages that function into a named organisational approval with post-holders attached. The FAA distributes the same obligations differently across the operator's own certificates and programmes, without a single container called "CAMO".
So an American engineer asked whether their organisation has a CAMO will often say no, and be entirely correct, while doing the work every day.
Where it starts costing money
For an operator inside one framework, this is a terminology curiosity.
For an operator spanning both, it is a duplication problem. The same fleet, the same directives, the same records, have to be presented two different ways to two different authorities. And because most software in this category is built around the paperwork of one framework rather than around the airworthiness work itself, the usual answer is to keep the evidence twice.
Keeping it twice means reconciling it twice, and reconciliation is where compliance failures actually come from. As covered in how to prepare for a CAMO audit, most findings are not failures of engineering judgement. They are two records of the same fact that stopped agreeing with each other.
The underlying facts do not change
Here is what does not vary between frameworks.
An airworthiness directive either applies to a given aircraft, engine or component, at a given serial range and modification standard, or it does not. A rectification interval either has expired or it has not. A task was either carried out by a qualified person under a valid approval, or it was not.
Those are facts about the aircraft, not about the regulator. The regulator decides how they must be presented, and the presentation is the part that differs.
Software that models the facts can present them either way. Software that models one authority's forms has to be duplicated to serve the other.
What that means in practice
One underlying set of records. Directive compliance assessed against the live fleet configuration, so that when a component moves between tails its limits and directives follow it. Evidence produced by filtering those records rather than assembled into a pack by hand.
That is what CAMO software built for operators in more than one jurisdiction has to do, and it is why the system is built around the airworthiness work rather than around any one authority's paperwork.
The maintenance side follows the same principle: the work performed by a Part 145 approved organisation, the sign-offs and the evidence behind each one, are the same facts regardless of who is asking. See the digital technical log.
Common questions
Is CAMO an FAA concept?
No. CAMO is a European term, defined within the EASA framework as an organisational approval for continuing airworthiness management with named post-holders and a documented scope. US operators perform the same function and are held to an equivalent standard of continuing airworthiness, but the FAA structures the requirement differently across the operator's own certificates and programmes and does not use the term. An operator asked whether they have a CAMO may correctly answer no while performing the work daily.
What is the FAA equivalent of a CAMO?
There is no single FAA approval that maps one to one onto a Part-CAMO, which is the root of the confusion. The obligations that an EASA framework gathers into one organisational approval are, in the FAA system, distributed across the operator's own certificate, its approved maintenance programme and its recordkeeping requirements. The work is equivalent; the container is not. Operators holding approvals in both frameworks need records that satisfy each without being maintained twice.
