What Is a CAMO in Aviation? Continuing Airworthiness Explained

A CAMO is a continuing airworthiness management organisation, approved by a civil aviation authority such as the European Union Aviation Safety Agency (EASA). It manages, rather than physically performs, the tasks that keep an aircraft airworthy over its operational life.

So what is a CAMO in practice? It is the planning, tracking, and records function behind continuing airworthiness, answerable to its authority for that work and for the standards it maintains.

Under EASA rules, Part-CAMO sets the requirements for a continuing airworthiness management organisation, while Part-M holds the technical rules for keeping an aircraft airworthy. Approval sets the scope, meaning the aircraft types and tasks the organisation may manage.

Part-CAMO therefore describes what an approved organisation must do, and the approval scope shows where its authority starts and stops. Together, the two form the EASA framework for continuing airworthiness.

The daily work of a CAMO centres on three tasks:

• Develops and updates the Aircraft Maintenance Programme (AMP).
• Schedules inspections and ensures compliance with Airworthiness Directives (ADs).
• Maintains complete, auditable technical records.

Together, these keep scheduled inspections, mandatory directives, and records aligned, so every maintenance event is planned and documented. Records are the proof that each task was properly completed and signed off, so audits run smoothly.

• CAMO: manages and oversees continuing airworthiness and coordinates the work.
• Part-145 maintenance organization: physically performs the maintenance, often in a hangar.

One plans and controls, while the other executes. Oversight and execution are separate roles, so an owner usually needs both, and the CAMO works with the Part-145 organization to schedule and release each task. Owners should know which organization is responsible for each step. 

A CAMO conducts or supports the airworthiness review of an aircraft. The review underpins the Airworthiness Review Certificate (ARC), which confirms continuing airworthiness. The review examines documented records alongside a physical survey of the aircraft, and an aircraft generally needs a valid ARC to fly. Treat the ARC as the visible result of consistent record-keeping. Without that continuity of records, an airworthiness review becomes slower and harder to complete.

Most business jets are complex motor-powered aircraft, and on the registers of EASA member states, they require a CAMO to manage continuing airworthiness. CAMO oversight for EU-registered aircraft therefore applies to owners who register in Europe, for example through the Irish EJ registry. In CAMO aviation terms, the register decides which rules apply, and the CAMO obligation follows the aircraft onto that register. 

Continuing airworthiness is one pillar of full aircraft management, alongside safety, crewing, and operations. Managed ownership consolidates these obligations under one accountable structure, so maintenance oversight sits beside every other duty. The turnkey aircraft management program shows how these duties come together.  Asking what a CAMO is, and what it covers, helps owners judge how a structure handles airworthiness. This structure keeps responsibility clear for the owner at every stage.

Four checks help owners compare providers:

• Approval scope that matches your aircraft type and register.
• Records systems that are auditable and complete.
• Reporting transparency on maintenance status.
• Responsiveness when questions or defects arise.

Treat these as neutral criteria for any provider. Approval scope matters most when an aircraft type or register is unusual, so ask for written evidence of each point before you decide.

During a sale or import, continuing airworthiness records and reviews are critical to a clean transfer. A CAMO helps maintain records continuity and supports the airworthiness review through the transition, whether for a pre-purchase check or an import onto a new register. Complete records let an aircraft move between owners or registers without gaps in its airworthiness history. That continuity supports every later review.

Continuous monitoring tracks inspections, Airworthiness Directives, and component life. Digital technical records and CAMO software support auditable compliance tracking, so every task’s status is visible when needed. In CAMO aviation practice, software supports judgment but does not replace it, because qualified people still decide how to handle each finding.  Component life tracking, for example, shows in advance when a part approaches its life limit.

Through Aircraft Management, ACASS absorbs regulatory, safety, and maintenance responsibilities for owners. ACASS holds an Irish Air Operator Certificate (since 2020), manages aircraft in Europe, and is IS-BAO Stage 3 registered, with 30+ years across 56 countries. Specialists coordinate the details for each aircraft. See aircraft management in Ireland for how this works in Europe, or Connect With a Specialist to discuss your aircraft. Specialists coordinate the details for each aircraft.

What is a CAMO? It is the organization that manages an aircraft’s continuing airworthiness, distinct from a Part-145 organization that performs the maintenance. EU-registered business aircraft owners rely on this oversight to keep records, inspections, and directives under control. A clear view of that division of roles helps owners ask better questions of any provider. Connect With a Specialist to talk through how continuing airworthiness fits your aircraft.
