EASA Part CAO – Combined Airworthiness Organisation Regulatory Obligations for Regulatory Authorities – 2 Days


A Combined Airworthiness Organisation (Part CAO) provides a new simplified organisation approval for General Aviation (GA) which provides an alleviation against many of the requirements (For example – No Safety Management System (SMS))

The Part-CAO was not created only to replace the Subpart F Maintenance Organisation, but rather to offer a completely new type of organisation, which is specifically adapted to the needs of GA.

In addition, there is typically a reduced involvement of the Competent Authority
A Combined Organisation is allowed to obtain the following privileges

a) Maintenance

b) Continuing airworthiness management

c) Airworthiness review

d) Permit to fly

This training which is focused on the professional development of key stakeholders is designed to provide participants with a detailed understanding of all elements of an integrated CAO.
