Can the Quality Officer of an organisation Part 145, with certification authorisation with scope of basic maintenance (Category LMA license), sign the CRS for basic maintenance work?

Certifying or releasing a maintenance task by means of a TLB, CRS or EASA Form 1 is considered to be the last action in the production process of a maintenance facility, and this task is the privilege of the certifying staff duly authorised to do so. A Quality Manager of a maintenance centre, as well as the Quality System auditors, should not be involved in this production process (AMC 145.A.65 (c) 1-11), since when managing/performing quality audits, an essential component of the Quality System, the required independent nature of the quality system would be infringed. 
 
Depending on the size of the organisation in some cases, and in the reverse direction of the case being dealt with, competent personnel, without being quality auditors, are allowed to carry out quality audits of production processes in which they are not directly involved, but it is not admitted that the Head of the Quality System or Personnel Auditor exercises the certification privileges.
