4.  
Documentation accompanying all material should clearly relate to the particular material and contain a conformity statement plus both the manufacturing and supplier source. Some material is subject to special conditions such as storage condition or life limitation etc. and this should be included on the  documentation  and / or material packaging.

5.  
CAD form 1 or equivalent is not normally issued for such material and therefore none should be expected. The material specification is normally identified in the TC holder’s data except in the case where the State of Design or CAD has agreed otherwise.

6.  
Items purchased in batches (fasteners etc.) should be supplied intact in the original equipment manufacturer (OEM) package. Packaging should state the P/N, batch number and the quantity specified in the package. The documentation accompanying the material should contain P/N, lot number and the supplied quantity, and the manufacturing sources. If the material is acquired  from different lots, acceptance  documentation  for each lot should be supplied.

AMC M.502 Component maintenance 
Component removal from and installation on an aircraft is considered to be aircraft maintenance and not component maintenance. As a consequence, MCAR-M.502 requirements do not apply to this case. 
AMC M.502(b) and (c) Component maintenance
MCAR-M.502(b) and (c) allow the performance of certain component maintenance, in accordance with component maintenance data, to maintenance organisations not holding the corresponding B/C rating and to independent certifying staff, subject to the agreement of CAD.
This should only be permitted by CAD in the case of simple component maintenance, where CAD is satisfied that the certifying staff are appropriately qualified and the proper tooling and facilities are available. It is important to note that for more complex componentmaintenance, special qualifications may be required and it is not enough with holding a Part-66 aircraft maintenance licence.
AMC M.504 (a) - Control of unserviceable components
A component continues to be unserviceable until a decision is taken pursuant to AMC MCAR-M.605 (c) 6
AMC M.504 (b) - Control of unserviceable components
1.  
MCAR-M.801(b)(2) and MCAR-M.801(c) certifying staff or the Section 1 Subpart F /MCAR-145 approved maintenance organisation performing maintenance  should ensure proper identification of any unserviceable components.

2.  
The unserviceable status of the component should be clearly declared on a tag together with the component identification  data and any information  useful to define actions necessary to be taken. Such information should state, as applicable, in service times, maintenance status, preservation status, failures, defects or malfunctions reported or detected exposure to adverse environmental conditions, if the component has been involved in or affected by an accident/incident. Means should be provided to prevent unwanted separation of this tag from the component.

3.  
MCAR-M.801(b)(2) and MCAR-M.801(c) certifying staff performing aircraft maintenance should send, with the agreement of the aircraft owner/lessee, any unserviceable component to a maintenance organisation approved under Section 1 Subpart F or MCAR-145 for controlled storage, or transfer the custody of the component to the owner itself under the conditions specified in MCAR-M.504(b).

“A secure location under the control of an approved maintenance organisation” means a secure location for which security is the responsibility of the approved maintenance organisation. This may include facilities established by the approved maintenance organisation at locations different from the main maintenance facilities. These locations should be identified in the relevant procedures of the approved maintenance organisation.
