4.  
The purpose of the EASA Form 1 (see also Part-M Appendix II) is to release com-ponents after manufacture and to release maintenance work carried out on such components under the approval of a competent authority and to allow components removed from one aircraft/component to be fitted to another aircraft/ component.

5.  
For the purpose of Part-M, a document equivalent to an EASA Form 1 may be:

(a)  
a release document issued by an organisation under the terms of a bilateral agreement signed by the European Community;

(b)  
a release document issued by an organisation approved under the terms of a JAA maintenance bilateral agreement until superseded by the corresponding agree-ment signed by the European Community;

(c)  
a JAA Form One issued prior to 28 November 2004 by a JAR 145 organisation approved by a JAA Full Member State;

(d)
in the case of new aircraft components that were released from manufacturing prior to the Part-21 compliance date, the component should be accompanied by a JAA Form One issued by a JAR 21 organisation approved by a JAA Full Member Authority and within the JAA mutual recognition system;

(e)  
a JAA Form One issued prior to 28 September 2005 by a production organisation approved by a competent authority in accordance with its national regulations;

(f)  
a JAA Form One issued prior to 28 September 2008 by a maintenance organisa-tion approved by a competent authority in accordance with its national regula-tions;

(g)  
a release document acceptable to a competent authority according to the provi-sions of a bilateral agreement between the competent authority and a third coun-try until superseded by the corresponding agreement signed by the European Community. This provision is valid provided the above agreements between the competent authority and a third country are notified to the Commission and to the other competent authorities in accordance with Article 9 of Regulation (EC) No 1592/2002.

(h)  
a release document issued under the conditions described in Article 4, point 4 of Regulation (EC) No 2042/2003;

(i)  
paragraphs (f) and (g) do not apply to the Part-145 maintenance environment.

6.  Any item in storage without an EASA Form 1 or equivalent cannot be installed on aircraft registered in a Member State unless an EASA Form 1 is issued for such item by an appropriately approved maintenance organisation in accordance with AMC
M.A.613 (a)
AMC M.A.501 (b) Installation
1.  
The EASA Form 1 identifies the airworthiness status of an aircraft component. Block 12 ‘Remarks’ on the EASA Form 1 in some cases contains vital airworthiness related information (see also Part-M Appendix II) which may need appropriate and necessary actions.

2.  
The fitment of replacement components should only take place when the person referred to in M.A.801 or the M.A. Subpart F or Part-145 maintenance organisation is satisfied that such components meet required standards in respect of manufacture or maintenance, as appropriate.

3.  
The person referred to under M.A.801 or the M.A. Subpart F or Part-145 approved maintenance organisation should be satisfied that the component in question meets the approved data/standard, such as the required design and modification standards. This may be accomplished by reference to the (S)TC holder or manufacturer’s parts catalogue or other approved data (i.e. Service Bulletin). Care should also be taken in ensuring compliance with applicable AD and the status of any service life-limited parts fitted to the aircraft component.

AMC M.A.501 (c) Installation
1.  Standard parts are:
(a) parts  manufactured in complete compliance with an established industry, Agency, competent authority or other Government specification which includes design, manufacturing, test and acceptance criteria, and uniform identification requirements. The specification should include all information necessary to pro-duce and verify conformity of the part. It should be published so that any party may manufacture the part. Examples of specifications are National Aerospace Standards (NAS), Army-Navy Aeronautical Standard (AN), Society of Automotive Engineers (SAE), SAE Sematec, Joint Electron Device Engineering Council, Joint Electron Tube Engineering Council, and American National Standards Institute (ANSI), EN Specifications etc…
