Continuing airworthiness management organisation (CAMO) is a civil aviation organization authorized to schedule and control continuing airworthiness activities on aircraft and their parts[1] The scope of the CAMO is to organise and manage all documents and publications for Maintenance Organizations Part 145 and Part M approved, like development and management of aircraft maintenance programmes fulfilled.
A CAMO must also provide record keeping of maintenance performed.
In other words, a CAMO is responsible to the Air Operator Certificate (AOC) holder.
[2] General requirements to be met by a CAMO are facilities (offices and documentation storage), a Continuing Airworthiness Management Exposition (CAME) which must be approved by the competent authority of the country or EASA and company procedures (to comply with Part M requirements).
Like any other aviation organisation a CAMO is audited by authorities and must fulfill all requirements.
