Instandhaltungsbetrieb/ kombinierte Lufttüchtigkeitsorganisation (CAO) Genehmigung

If your company wishes to operate as a maintenance organization (Part-145) or combined airworthiness organization (CAO) in the aviation sector, you require approval from the German Federal Aviation Office. Changes are also subject to approval.

Aeronautical maintenance includes all activities in which aircraft, engines or components are overhauled, repaired, modified and tested. A Combined Airworthiness Organization (CAO) is responsible for the maintenance and continuing airworthiness management of non-complex aircraft. In order to operate as a maintenance organization or CAO, your company must first obtain approval from the German Federal Aviation Authority (LBA). All changes to the approval are also subject to approval.
