In aeronautical maintenance, safety is non-negotiable. To guarantee this, audits of the CAMO (Continuing Airworthiness Management Organization) and AMO (Approved Maintenance Organization) are essential. These periodic reviews ensure that each process complies with international standards and current regulations.

Why are these audits necessary?

The audits verify that the organizations comply with Regulation (EU) 1321/2014 and its annexes: Part-CAMO for the management of continued airworthiness and Part-145 for approved maintenance. Without them, there would be no guarantee of traceability, documentary control or technical supervision, pillars that support operational safety.

CAMO Audits: Strategic Control

A CAMO does not perform physical maintenance; Its role is to manage airworthiness. During the audit, the following are reviewed:

• Maintenance programme and its regulatory adaptation.
• Compliance with airworthiness (AD) directives and service bulletins.
• Management system and Compliance Monitoring, which replaced the old "Quality System".
• Integration of SMS (Safety Management System) for risk management.

The objective: to confirm that the CAMO maintains a continuous and documented control, issuing certificates such as the ARC (Airworthiness Review Certificate).

AMO Audits: Technical Execution

AMOs are responsible for physical maintenance. The audit assesses:

• Calibrated installations and tools.
• Staff competence (Part-66 licenses: B1, B2, C).
• Job records and traceability of parts.
• Compliance with procedures for inspections (A-Check, C-Check) and repairs.

The priority here is to ensure that each intervention is carried out in accordance with technical and safety standards.

How are they carried out?

The cycle includes:

• Planning: definition of scope and risks.
• Execution: documentary review, interviews and observation in hangar.
• Report and corrective actions: identification of findings and deadlines for correction.
• Follow-up: verification of implemented improvements.

CAMO and AMO audits are more than a legal requirement: they are the mechanism that ensures that each aircraft flies under the highest safety standards. Without them, the chain of trust in aviation would be broken.
