The competent authority shall compare the holder’s aircraft maintenance licence with the competent authority records and verify any pending revocation, suspension or change action pursuant to point 66.B.500. If the documents are identical and no action is pending pursuant to point 66.B.500, the holder’s copy shall be renewed for 5 years and the file endorsed accordingly.
If the competent authority records are different from the aircraft maintenance licence held by the licence holder:
1. the competent authority shall investigate the reasons for such differences and may choose not to renew the aircraft maintenance licence.
2. the competent authority shall inform the licence holder and any known maintenance organisation approved in accordance with Annex I (Part-M) Subpart F or Annex II (Part-145) that may be directly affected of such fact.
3. the competent authority shall, if necessary, take action in accordance with point 66.B.500 to revoke, suspend or change the licence in question.
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 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 or the 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.30, 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.
