Maintenance on aircraft

Maintenance activities on aircraft may only be carried out by organisation or specialised personnel who hold the necessary approvals. The FOCA issues a corresponding approval to organisation which have undergone an examination and have thus demonstrated that they meet the relevant legal requirements. The approval procedure may take several months, depending on the size of the organisation and the complexity of the involved activities.

After a maintenance organisation has been issued with an approval certificate it is periodically inspected and audited by the FOCA. If any discrepancies are identified, the organisation concerned is required to permanently rectify them within a deadline specified by the FOCA.

Maintenance approval certificates are issued for an indefinite period. However, maintenance organisation are obliged to notify the FOCA about any changes that could have an influence on the approval before the changes concerned are implemented. While taking account of the respective circumstances and minimum requirements, the FOCA will then specify the conditions or, where applicable, restrictions regarding the company’s continued activity as a maintenance provider.
