What is Subpart G ?

Subpart G typically refers to a section within a regulatory framework governing Continuing Airworthiness Management Organizations (CAMOs). In the previous article I explained what is CAMO in basic, now let’s get into more detail. Surpart G is most commonly associated with EASA Part-M, which defines continuing airworthiness requirements for aircraft and components within the European Union. Subpart G outlines the requirements for organizations responsible for managing the continuing airworthiness of aircraft to ensure their safe operation.

Key Features of Subpart G

1. Purpose

Subpart G governs the establishment, approval, and operation of CAMOs. These organizations are responsible for ensuring that aircraft comply with airworthiness standards throughout their lifecycle.

2. Organizational Approval

To operate as a CAMO, an organization must:

? Apply for approval from the relevant aviation authority (e.g., EASA or a national aviation authority).

? Demonstrate compliance with Subpart G requirements, including organizational structure, personnel qualifications, and operational procedures.

3. Responsibilities of CAMOs

CAMOs under Subpart G are tasked with:

? Aircraft Maintenance Programme (AMP): Developing, implementing, and maintaining an AMP tailored to each aircraft.

? Airworthiness Directives (ADs): Ensuring compliance with mandatory ADs issued by authorities.

? Defect Control: Managing defects identified during operations or maintenance.

? Records Management: Keeping detailed records of aircraft maintenance, repairs, and modifications.

? Maintenance Planning: Scheduling and coordinating maintenance activities to ensure compliance with regulatory requirements.

4. Key Personnel and Roles

Subpart G mandates that CAMOs designate key personnel, such as:

? Accountable Manager: Holds overall responsibility for ensuring the organization meets its obligations.

? Continuing Airworthiness Manager: Oversees airworthiness management activities.

? Quality Manager: Ensures compliance with quality standards and oversees audits of the CAMO’s processes.

5. Quality System

Subpart G requires CAMOs to establish a robust Quality System, including:

? Internal audits to identify deficiencies and ensure compliance.

? Processes for corrective and preventive actions.

? Regular reviews to assess the system’s effectiveness.

6. Continuing Airworthiness Management Exposition (CAME)

CAMOs must develop and maintain a CAME, a comprehensive document detailing:

? Organizational structure and responsibilities.

? Procedures for managing continuing airworthiness.

? Quality assurance processes.

The CAME must be approved by the aviation authority before the organization can be authorized to operate.

Key Activities of Subpart G CAMOs

? Development and oversight of aircraft maintenance schedules.

? Ensuring aircraft comply with safety regulations.

? Coordination with maintenance organizations (often Subpart F entities) for inspections and repairs.

? Issuance or recommendation for the issuance of Airworthiness Review Certificates (ARCs), depending on authorization.

Relation to Other Subparts

? Subpart F: Covers the approval and operation of maintenance organizations performing physical repairs and maintenance.

? Subpart I: Focuses on the issuance and renewal of Airworthiness Review Certificates (ARCs), often managed by Subpart G organizations.

Approval Process

1. The organization submits an application to the aviation authority.

2. The authority reviews the CAME, organizational setup, and compliance with Subpart G requirements.

3. After audits and inspections, approval is granted if the organization meets all requirements.

Conclusion

Subpart G is essential for ensuring aircraft remain airworthy and comply with safety regulations throughout their operational lives. It provides a framework for organizations to manage maintenance, repairs, and inspections in a structured and regulated manner.
