Show the text

(a)Airworthiness review staff already authorised to perform airworthiness review for an organisation approved in accordance Part-M Subpart F, Part-M Subpart G, Part-CAMO or Part-145 is considered to be authorised in accordance with Part-CAO when such organisation applies for a Part-CAO approval. This means that no additional supervision is needed to be authorised to be accepted to continue carrying out airworthiness reviews. This does not supersede the requirement for the organisation to ensure that all personnel is competent for the job they are authorised.

(b)‘Experience in continuing airworthiness’ in CAO.A.045(a) refers to any appropriate combination of experience in tasks related to aircraft maintenance and/or continuing airworthiness management and/or surveillance of such tasks.

(c)‘Appropriate recent continuing airworthiness experience’ in CAO.A.045(c) refers to the fact that in order to keep the validity of the airworthiness review staff authorisation, the airworthiness review staff should have either:

(1)been involved in continuing airworthiness management activities for at least 6 months in every 2-year period; or

(2)conducted at least one airworthiness review in the last 12-month period.

(d)In order to restore the validity of the authorisation, the airworthiness review staff should conduct at a satisfactory level an airworthiness review under the supervision of the competent authority or, if accepted by the competent authority, under the supervision of another currently valid authorised airworthiness review staff of the CAO concerned in accordance with an approved procedure.

(e)A person that holds a relevant engineering degree or an aircraft maintenance technician qualification with additional education should be considered as holding the equivalent to an aeronautical degree. ‘Relevant engineering degree’ refers to an engineering degree from mechanical, electrical, electronic, avionic or other studies relevant to the maintenance and continuing airworthiness of aircraft/aircraft components.
