AMC No 2 to 21.A.133(b) and (c) Eligibility – Link between design and
production organisations

ED
Decision 2012/020/R

In
accordance with [AMC No 1 to 21.A.133(b) and (c)](#_DxCrossRefBm1649096915) the POA
holder must demonstrate to the competent authority that it has entered into an
arrangement with the design organisation. The arrangement must be documented
irrespective of whether the two organisations are separate legal entities or
not.

The documented arrangement must facilitate
the POA holder to demonstrate compliance with the requirement of [21.A.133](#_DxCrossRefBm1649096911)(b) and (c) by means of
written documents agreed.

In the
case where the design organisation and POA holder are part of the same legal
entity these interfaces may be demonstrated by company procedures accepted by
the competent authority.

In all
other cases to define such a design/production interface the following sample
format is offered:

Title:
The title of the relevant document must clearly indicate that it serves the
purpose of a design/production interface arrangement in accordance with [21.A.133](#_DxCrossRefBm1649096911)(b)
and (c).

Commitment: The document must include the
basic commitments between the design organisation and the POA holder as
addressed in [AMC 21.A.4](#_DxCrossRefBm1649096914) and [AMC No 1 to 21.A.133(b) and (c)](#_DxCrossRefBm1649096915).

Relevant
Procedures: Identify an entry point into the documentary system of the
organisations with respect to the implementation of the arrangement (for
example a contract, quality plan, handbooks, common applicable procedures,
working plans etc.).

Scope
of arrangement: The scope of arrangement must state by means of a list or
reference to relevant documents those products, parts or appliances that are
covered by the arrangement.

Transfer of applicable design data:
Identify the relevant procedures for the transfer of the applicable design
data required by [21.A.131](#_DxCrossRefBm1649097182) and [GM 21.A.131](#_DxCrossRefBm1649097183) from the design
organisation to the POA holder. The means by which the design organisation
advises the POA holder whether such data is approved or not approved must also
be identified (ref. [21.A.4](#_DxCrossRefBm1649096909)/[AMC 21.A.4](#_DxCrossRefBm1649096914)).

Direct
Delivery Authorisation: Where the design organisation and the POA holder are
separate legal entities the arrangement must clearly identify whether
authorisation for direct delivery to end users is permitted or not.

Where
any intermediate production/design organisations are involved in the chain
between the original design organisation and the POA holder evidence must be
available that this intermediate organisation has received authority from the
design organisation to grant Direct Delivery Authorisation.

Signature:
[AMC No 1 to 21.A.133(b) and (c)](#_DxCrossRefBm1649096915)
requests the identification of the responsible persons/offices who control the
commitments laid down in the arrangement. Therefore the basic document must be
signed mutually by the authorised representatives of the design organisation
and the POA holder in this regard.
