EASA Part 21 / CS25 Review for CAMO Staff – 2 Days


The role of the CAMO is wide-reaching with an obligation to ensure the ongoing status of the Continuing Airworthiness of the Operators Fleet.

Having a detailed awareness related to the Management of Repairs and Supplemental Type Certificates (STCs) is an important element of the full role of Continuing Airworthiness.

The course focuses on all elements related to the interface between the Operators CAMO and Part 21 – Including the management of the aircraft configuration.

In addition, consider specific elements within CS 25 that have a direct bearing on the CAMO Process. There are a series of technical codes that must be followed to ensure the design of the various products and parts are fully compliant with all certification requirements. Related to Large Aircraft this Technical Code is known as CS-25 Large Aeroplane Certification.

This 2-day intensive course considers the roles and responsibilities of the PART M CAMO and the interfaces with PART 21 Subpart G Production Organisations and Part 21 Subpart J Design Organisations to include awareness of CS 25 requirements focused on the Oversight of Maintenance Activities, Management of STC Mods and Repairs and the issue of Permit to Fly.

M.A.711 (c) A continuing airworthiness management organization whose approval includes the privileges referred to in point M.A.711(b) may additionally be approved to issue a permit to fly by Part 21A.711(d) of the Annex (Part-21) to Regulation (EC) No 748/2012 for the particular aircraft for which the organization is approved to issue the airworthiness review certificate when the continuing airworthiness management organization is attesting conformity with approved flight condition.
