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 organisations 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 organisations 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.

FOCA supervision for companies that service aircraft from the USA, Canada and Brazil

Swiss maintenance companies that maintain aircraft registered in USA, Canada or Brazil will no longer require additional supervision by the aviation authorities FAA, TCCA and/or ANAC. The FOCA has signed a corresponding agreement BASA-MIP with the FAA, a Working Arrangement with the TCCA and an MOU with ANAC.

These agreements represent a great relief for all Swiss maintenance organizations with the corresponding approval. On the one hand, additional high costs and redundant supervision are avoided. Now the FOCA can take over this task on behalf of the FAA, TCCA and ANAC.

For the companies this means significantly less additional work and lower costs than before. In the future, compliance with European law (EASA Part-145) and some additional provisions of the "Special Conditions", which are listed in the corresponding regulations, will be sufficient for obtaining and maintaining an FAA, TCCA and/or ANAC certification. These agreements are in accordance with those of EASA.

Bilateral Aviation Safety Agreements (BASA, Working Arrangement and MOU)

The Agreements are published on the website: "Safety -International affairs - Technical agreements".
