RA 4809 - Acceptance of Components (MRP 145.A.42)
Rationale
It is essential that only serviceable and approved components are used in the
maintenance of aircraft. Therefore, a suitable method of classifying and labelling
components is required.
This regulation also details the requirements for an organization to follow when
arranging for a component to be locally manufactured/fabricated.

Regulation
4809(1)
Component Classification (MRP 145.A.42(a))
4809(1) Components shall be classified and appropriately
segregated into the following categories:
a. Components which are in a serviceable condition,
released on an MOD Form 731 (see MAP-02), or
equivalent.
b. Unserviceable components to be maintained in
accordance with RA 4800-4849 (MRP Part 145).
c. Unsalvageable/Scrap components which are classified
in accordance with RA 4809(4) (MRP 145.A.42(d)).
d. Standard parts used on an aircraft, engine, propeller or
other aircraft component when specified in the
manufacturer's illustrated parts catalogue and/or the
technical information.
Note:
These parts shall only be considered serviceable if
accompanied by a manufacturer’s Certificate of
Conformity (or equivalent).
e. Material both raw and consumable used in the course of
maintenance when the organization is satisfied that the
material meets the required specification and has
appropriate traceability.
Note:
All material shall only be considered serviceable if
accompanied by documentation clearly relating to the
particular material and containing a ‘conformity to
specification’ statement plus both the manufacturing and
supplier source.

1.
With respect to RA 4809(1)(a) (MRP 145.A.42(a)(a)), only the following
documents should be accepted as an equivalent to the MOD Form 731 for identifying
1
a component as ►ready for release to service ◄:
a.
A European Aviation Safety Agency (EASA) Form 1 ►issued by an
EASA approved organization for products, parts and appliances within the
scope of such an approval under the following conditions only:
(1)
New parts issued under EASA Pt 21 regulations.
2
(2)
Maintained, repaired or overhauled parts having applicability to
civilian registered aircraft, that are also utilized on military registered
3
aircraft, released under Practice 1 of the EASA Certificate of release
4
regulations .
b.
A UK MAA Form 1 (only when issued by a maintenance organization
approved by the MAA and only for products, parts or appliances within the
scope of that approval). The format and notes for completion of a UK
MAA Form 1 are at Annex A.
c.
A European Defence Agency (EDA) participating Member State’s
national derivative of the European Military Airworthiness Requirements
(EMAR) Form 1 template (only when issued by a maintenance organization
appropriately approved by the MAA or approved by an authority with which the
5
MAA has an extant Recognition with a scope that includes the acceptability of
their maintenance organization approvals).◄
d.
A Certificate of Conformity (CoC) or MOD Form 640 (these documents
are acceptable only when ►they meet the information requirements of Defence
Condition (DEFCON) 627 and traceability of certification can be maintained,
and◄ the item is in unbroached primary packaging).
e.
MOD Form 3910 (for consumable components only).
Additional AMC – Military Maintenance Organizations (MMOs) only
To be read in conjunction with the Common AMC.
2.
Prior to returning an item of technical equipment to the supply/logistics
organization, it should be conditioned in order to determine its serviceability state.
Such conditioning should be in accordance with the processes contained within MAP01 Chapter 9.5.
Additional AMC – Approved Maintenance Organizations (AMOs) only
To be read in conjunction with the Common AMC.
3.
When a ‘standard part’ is received with a CoC, the accreditations of the
originator should be established as far as reasonably practicable. AMOs should have
a procedure in place for assessing suppliers.

EASA have clarified that the use of an EASA Form 1 under Practice 1 as an airworthiness release certificate for a repaired part that
is only eligible to be installed in a military aircraft is considered improper by EASA, and not in line with the provisions of the Basic
Regulation – EASA Maintenance Regulations Section, 06 Apr 2016.

MOD logistics policy permits MOD Form 640s and CoCs to be held at the
depot/Main Operating Base (MOB) where the item(s) is initially received. Therefore,
provided that each individual component remains in unbroached primary packaging,
these items may be dispatched to maintenance organizations without a copy of their
respective MOD Form 640 or CoC attached. The absence of this accompanying
document is acceptable provided that ►all of the following are met:◄
a.
The item was accompanied by a MOD Form 640 or CoC on receipt into
the MOD. If required, the depot/MOB can provide the original MOD Form 640 or
CoC for clarification in this regard. ►MOD◄ policy is detailed in ►the Defence

Logistics Framework (DLF) ◄.
b.
The item has been received by the maintenance organization through the
MOD ►◄, with an accompanying issue voucher, as a serviceable item.
c.
The item is delivered to the maintenance organization in unbroached
primary packaging.
d.
All technical information (modification state, component life, etc), as
applicable, is available on certified documentation elsewhere.
6.
For clarification, the CoC is the document produced by the component
manufacturer or contracted maintainer that contains a mark (normally a signature or
stamp) to certify its quality (following manufacture) or serviceability (following
maintenance). It may also be known as the Certificate of Conformance, or Certificate
of Compliance.

and Airborne Equipment in accordance with the requirements of MAP-01 Chapters 6.3
and 11.7.
Additional AMC - AMOs only
17. AMOs should only locally manufacture/fabricate parts within its own facilities in
accordance with procedures identified in the exposition and approved by the MAA.
18. The agreement by the MAA for the local manufacture/fabrication of parts by the
AMO should be formalized through the approval of a detailed procedure in the
Maintenance Organization Exposition.
19. Local manufacture/fabrication, inspection, assembly and test should be clearly
within the technical and procedural capability of the AMO.
20. Items locally manufactured/fabricated by an AMO should only be used by that
organization in the course of overhaul, maintenance, modifications, or repair of aircraft
or components undergoing work within its own facility. The permission to locally
manufacture/fabricate does not constitute approval for manufacture, or to supply
externally. A MOD Form 731 (or equivalent) annotated in red, “FABRICATED ITEM
IAW RA 4809(3) (MRP 145.A.42(c)) FOR EXCLUSIVE USE BY THE FABRICATING
ORGANIZATION WITHIN ITS OWN FACILITIES” should be attached to the part. This
prohibition also applies to the bulk transfer of surplus inventory, in that locally
manufactured/fabricated parts are physically segregated and excluded from any
delivery certification.
21. Local manufacture/fabrication of parts, modification kits, etc., for onward supply
and/or sale, should not be conducted by an AMO, unless they have been specifically
contracted to produce items by the MOD. If separately contracted, then this
production would be considered to be outside of the MRP Part 145 approval.
22. When locally manufacturing/fabricating parts, care should be taken to ensure
that the data used includes details of part numbering, dimensions, materials,
processes, and any special manufacturing techniques, special raw material

specification or/and incoming inspection requirement and that the approved
organization has the necessary capability. That capability should be defined by way of
exposition content. Where special processes or inspection procedures are defined in
the approved data, which are not available at the organization, the organization
should not locally manufacture/fabricate the part unless the aircraft Type
Airworthiness Authority (TAA) gives an approved alternative. This principle also
applies to the technique of 3D printing/additive manufacturing.
23. All locally manufactured/fabricated parts should be in accordance with technical
information provided in overhaul or repair manuals, modification schemes and service
bulletins, drawings or otherwise approved by the TAA.
Note:
Items should not be locally manufactured/fabricated to pattern unless an
engineering drawing of the item is produced which includes any necessary
manufacturing/fabrication processes and which is acceptable to the TAA.
24. For civil-derivative aircraft, where a TC-holder, design organization or an
approved production organization is prepared to make available complete data which
is not referred to in aircraft manuals, ►service bulletins◄ or SI(T)s, but provides
manufacturing drawings for items specified in parts lists, the local
manufacture/fabrication of these items should not be considered as within the scope
of an organization’s approval, unless agreed otherwise by the TAA in accordance with
a procedure specified in the exposition.
Inspection and identification (AMOs only)
25. Any locally manufactured/fabricated part should be subjected to an inspection
stage before, separately, and preferably independently from, any inspection of its
installation. The inspection should establish full compliance with the relevant
manufacturing data, and the part should be unambiguously identified as fit for use by
stating conformity to the approved data.
26. Adequate records should be maintained of all such local
manufacture/fabrication processes including heat treatment and the final inspections.
27. All parts, unless its size prohibits it, should carry a part number which clearly
relates it to the manufacturing/inspection data. Additional to the part number, the
organization's identity should be marked on the part for traceability purposes.

34. Caution must be exercised to ensure that unsalvageable components are
disposed of in a manner that does not allow them to be returned to service since, in
some instances, these items have reappeared for sale to active inventories of the
aviation community. Therefore, organizations disposing of unsalvageable aircraft
components must consider the possibility of such components later being
misrepresented and sold as serviceable components.
