4. The workcard/worksheet system may take the form of, but is not limited to, the fol-lowing:
· a format where the mechanic writes the defect and the maintenance action taken together with information of the maintenance data used, including its revision status,
· an aircraft log book that contains the reports of defects and the actions taken by authorised personnel together with information of the maintenance data used, including its revision status,
· for maintenance checks, the checklist issued by the manufacturer (i.e., 100H checklist, Revision 5, Items 1 through 95)
5. Maintenance data should be kept up to date by: -subscribing to the applicable amendment scheme, -checking that all amendments are being received, -monitoring the amendment status of all data.

AMC M.A.402 (a) Performance of maintenance
1.
When working outside the scope of an approved maintenance organisation person-nel not authorised to issue a CRS should work under the supervision of certifying personnel. They may only perform maintenance that their supervisor is authorised to release, if the supervisor personally observes the work being carried out to the extent necessary to ensure that it is being done properly and if the supervisor is readily available, in person, for consultation. In this case licensed engineers should ensure that each person maintaining an aircraft or component has had appropriate train-ing or relevant previous experience and is capable of performing the task required, and that personnel who carry out specialised tasks such as welding are qualified in accordance with an officially recognised standard.
2.
In the case of limited Pilot-Owner maintenance as specified in M.A.803, any person maintaining an aircraft which they own or jointly own, provided they hold a valid pilot licence with the appropriate type or class rating, may perform the limited Pilot-owner maintenance tasks in accordance with Appendix VIII of Annex I (Part-M) of Regulation (EC) No 2042/2003.
3.
The general maintenance and inspection standards applied to individual mainte-nance tasks should meet the recommended standards and practices of the organi-sation responsible for the type design which are normally published in the mainte-nance manuals.
In the absence of maintenance and inspection standards published by the organisation responsible for the type design maintenance personnel should refer to the relevant aircraft airworthiness standards and procedures published or used as guidance by the Agency or the competent authority. The maintenance standards used should contain methods, techniques and practices acceptable to the Agency or competent authority for the maintenance of aircraft and its components.
4.
Independent inspections.
4.1 The manufacturer’s instructions for continued airworthiness should be followed when determining the need for an independent inspection.
4.2 In the absence of maintenance and inspection standards published by organisa-tion responsible for the type design, maintenance tasks that involve the assembly or any disturbance of a control system that, if errors occurred, could result in a failure, malfunction, or defect endangering the safe operation of the aircraft should be considered as flight safety sensitive maintenance tasks needing an independent inspection. A control system is an aircraft system by which the flight path, attitude, or propulsive force of the aircraft is changed, including the flight, engine and propeller controls, the related system controls and the associated operating mechanisms.
4.3 Independent inspections should be carried out by at least two persons, to ensure correct assembly, locking and sense of operation. A technical record of the inspections should contain the signatures of both persons before the relevant CRS is issued.
