AMC1 145.B.310(a) Initial certification procedure

CAA ORS9 Decision No. 38

AUDIT

(a) The CAA should determine how and by whom the audit should be conducted. For example, it will be necessary to determine whether one large team audit, a short series of small team audits, or a long series of single surveyors audits is most appropriate for the particular situation.

(b) The audit may be structured so as to verify the organisation’s processes related to a product line. For example, in the case of an organisation with Airbus A310 and A320 ratings, the audit should concentrate on the maintenance processes of one aircraft type only for a full compliance check, and depending upon the result, the second aircraft type may only require a sample check against those aspects that were seen to be weak regarding compliance for the first type.

(c) In determining the scope of the audit and which activities of the organisation will be assessed during the audit, the privileges of the approved organisation should be taken into account, e.g. their approval to carry out airworthiness reviews.

(d) The CAA auditing surveyors should always ensure that they are accompanied throughout the audit by a senior member of the organisation, who is normally the compliance monitoring manager. The reason for being accompanied is to ensure that the organisation is fully aware of any findings raised during the audit.

(e) At the end of the audit, the auditing surveyor should inform the senior member of the organisation of all the findings that were raised during the audit.
