2.  
Persons authorised to access the system should be maintained at a minimum to ensure that records cannot be altered in an unauthorised manner or that such confi-dential records become accessible to unauthorised persons.

3.  
The competent authority should be granted access to the records upon request.

ED 2006/11/R
AMC M.A.608 (a) Components, equipment and tools
1.  
Once the applicant for M.A. Subpart F approval has determined the intended scope of approval for consideration by the competent authority, it will be necessary to show that all tools and equipment as specified in the maintenance data can be made avail-able when needed.

2.  
All such tools should be clearly identified and listed in a control register including any personal tools and equipment that the organisation agrees can be used.

3.  
For tools required on an occasional basis, the organisation should ensure that they are controlled in terms of servicing or calibration as required.

AMC M.A.608 (b) Components, equipment and tools
1.  
The control of these tools and equipment requires that the organisation has a pro-cedure to inspect/service and, where appropriate, calibrate such items on a regular basis and indicate to users that the item is within any inspection or service or calibra-tion time-limit. A clear system of labelling all tooling, equipment and test equipment is therefore necessary giving information on when the next inspection or service or calibration is due and if the item is unserviceable for any other reason where it may not be obvious. A register should be maintained for all the organisation’s precision tooling and equipment together with a record of calibrations and standards used.

2.  
Inspection, service or calibration on a regular basis should be in accordance with the equipment manufacturers’ instructions except where the M.A. Subpart F organisation can show by results that a different time period is appropriate in a particular case.

3.  
In this context officially recognised standard means those standards established or published by an official body whether having legal personality or not, which are widely recognised by the air transport sector as constituting good practice.

AMC M.A.609 Maintenance Data

When an organisation uses customer provided maintenance data, the scope of approval indicated in the maintenance organisation manual should be limited to the individual aircraft covered by the contracts signed with those customers unless the organisation also holds its own complete set of maintenance data for that type of aircraft.

ED2008/013/R
AMC M.A.610 Maintenance work orders

“A written work order” may take the form of, but not limited to, the following:
- A formal document or form specifying the work to be carried out. This form may be provided by the continuing airworthiness management organisation managing the aircraft, or by the maintenance organisation undertaking the work, or by the owner/ operator himself. 
- An entry in the aircraft log book specifying the defect that needs to be corrected. 

ED 2010/002/R
AMC M.A.613 (a) Component certificate of release to service
1.  
An aircraft component which has been maintained off the aircraft requires the issuance of a certificate of release to service for such maintenance and another CRS to service in regard to being installed properly on the aircraft when such action occurs.

When an organisation maintains a component for use by the same organisation, an EASA Form 1 may not be necessary depending upon the organisation’s internal release procedures defined in the maintenance organisation exposition.

2.  
In the case of components in storage prior to Part-145, Part-M and Part-21 and not released on an EASA Form 1 or equivalent in accordance with M.A.501(a) or removed serviceable from active aircraft which have been withdrawn from service, this para-graph provides additional guidance regarding the conditions under which an EASA Form 1 may be issued.
