Part 145.A.30 (e) and the AMC requires an organisation to establish and control the competence of all personnel involved in maintenance. The AMC specifies that staff are assessed for competence before they work unsupervised. For the approved mechanic this would mean they could carry out the task to standard defined in the approved data and will notify supervisors of defects etc. Under these circumstances the CAA can accept a procedure that allows approved mechanics to sign cards for specific tasks. The main problem is that organisations have been unable to implement robust procedures to establish and control competence and demonstrate they are doing so in a consistent manner.
