AMC1 145.A.30(h) Personnel requirements
CAA ORS9 Decision No. 38
In accordance with points 145.A.30(h) and 145.A.35, the qualification requirements (basic licence, aircraft ratings, recent experience and recurrent training) are identical for certifying staff and for support staff. The only difference is that support staff cannot hold certification privileges when performing this role since during base maintenance, the release to service will be issued by category C certifying staff.
Nevertheless, the organisation may use as support staff (for base maintenance) persons who already hold certification privileges for line maintenance.
