AMC Acceptable means of compliance

## AMC 66.B.120 Procedure for the renewal of an aircraft maintenance licence validity

The competent authority should not carry out any investigation to ensure that the licence holder is in current [maintenance](https://avioverse.aero/glossary/easa/maintenance) practice as this is not a condition for the renewal of a licence. Ensuring the continued validity of the certification privileges is a matter for the approved Part-145 / M.A. Subpart F / Part-CAO maintenance [organisation](https://avioverse.aero/glossary/easa/organisation) or the [certifying staff](https://avioverse.aero/glossary/easa/certifying-staff) in accordance with M.A.801(b)1.

For the purpose of ensuring the continued validity of the certification privileges, the competent authority may, when periodically reviewing the organisations in accordance with 145.B.305, M.B.604 or CAO.B.055, or during on-the-spot checks, request the licence holder to provide documentary evidence of compliance with 66.A.20(b) when exercising certification privileges.
