Airworthiness Review Certificate

What is an Airworthiness Review Certificate?

The airworthiness review certificate is an official document issued after a comprehensive review of an aircraft’s maintenance records and physical condition. Its purpose is to confirm that the aircraft remains compliant with all applicable airworthiness requirements after its initial certification. The ARC is a requirement under EASA regulations for most aircraft, particularly those used in commercial operations or complex private operations.

ARC Aviation Process and Validity

The ARC is typically valid for 12 months and must be renewed annually. The review is conducted by a Continuing Airworthiness Management Organisation (CAMO) or, in some cases, by the competent authority. The process includes a detailed check of maintenance records, verification that all mandatory inspections and Airworthiness Directives have been complied with, and a physical inspection of the aircraft. If the aircraft meets all requirements, the ARC is issued or extended.

Relationship: Certificate of Airworthiness vs ARC

The Certificate of Airworthiness (CofA) is the primary document proving an aircraft’s compliance with design and safety standards at the time of manufacture or import. However, the CofA remains valid only as long as the aircraft continues to meet ongoing airworthiness requirements, which is demonstrated through the ARC. Without a valid ARC, the CofA is considered invalid, and the aircraft cannot be legally operated.

Who Determines Continuing Airworthiness?

The State of Registry has the legal authority to determine and oversee an aircraft’s continuing airworthiness. Day-to-day responsibility is often delegated to approved CAMOs, which manage the airworthiness review process, maintenance schedules, and compliance with regulations.

Prerequisites for ARC Issue

Before an ARC can be issued or extended, the aircraft must:

• Hold a valid Certificate of Airworthiness
• Be maintained according to an approved maintenance programme
• Have all required inspections, repairs, and modifications completed and documented
• Comply with all applicable Airworthiness Directives

Why the ARC Matters

The ARC is not just a paperwork exercise—it is a critical safety control, ensuring that aircraft remain airworthy throughout their operational life. It also supports international recognition of airworthiness, allowing aircraft to operate across borders under EASA and ICAO frameworks.
