Airworthiness does not depend on a single organization, but on a technical and regulated ecosystem where each actor plays a critical role.

Within this framework, CAMOs (Continuing Airworthiness Management Organisations) and AMOs (Approved Maintenance Organisations) form the essential architecture that supports the operational safety of any aircraft, from commercial aviation to special missions. Both operate under a highly traceable, auditable and regulated environment, ensuring that each maintenance task contributes to continued airworthiness.

A dual model based on technical responsibility and regulatory compliance

The CAMO acts as a managing and supervisory body. Your responsibility includes:

• Maintenance planning
• Document management and control of the maintenance program
• Tracking AD, SB, and regulatory requirements
• Continued airworthiness control
• Issuance or recommendation of the ARC (Airworthiness Review Certificate)

Its function is strategic: it does not physically intervene in the aircraft, but works through engineering, analysis and regulatory management.

For its part, the AMO represents technical execution under Part 145, with:

• Certified workshops, hangars and authorized personnel
• Calibrated and traceable tools
• Inspection techniques (including NDT)
• Strict adherence to approved methods and MOEs

The AMO materializes the decisions of the CAMO, ensuring that all actions are carried out in accordance with the approved standards, as required by the regulated aeronautical maintenance environment.

These two figures are complementary and not interchangeable:
without CAMO there is no strategic supervision; without AMO there is no certified execution.

The EASA 1321/2014 framework: the backbone of the system

European legislation articulates this CAMO/AMO binomial through a dual approach:

Part M / Part CAMO

• Continued airworthiness management
• Document and maintenance program control
• Regulatory assessment, airworthiness review and management staff competencies

Part 145

• Certification of maintenance organizations
• Staff qualification
• Facility Requirements
• Quality control and tool traceability, a key aspect also reflected in your internal materials.
• Compliance with approved methods

This framework defines not only what needs to be done, but how it needs to be demonstrated, reinforcing the importance of document traceability and process standardization, in line with what your documentation on CAMO/AMO control and audits also highlights.

The audit: structural verification of the entire system

CAMO and AMO audits act as a verification mechanism and are essential to confirm that:

• Management systems are working properly
• Organizations comply with applicable standards
• Document traceability is complete
• Technical decisions are based on verifiable data
• Hangar execution conforms to approved methods

They are the true stress test of the regulatory model, reinforcing operational safety through the early detection of deviations, as also described in your corporate materials.

A partnership that ensures ready-to-fly aircraft

Continued airworthiness is not a one-off process, but a sustained cycle that requires coherence between analysis and technical execution.

• The CAMO defines technical and regulatory direction.
• The AMO ensures that every action is executed in accordance with approved standards.

This dual system – technical planning + certified execution – allows each flight to take off with regulatory guarantees, technical integrity and document traceability, the three pillars that underpin safety in modern aviation.
