ED
Decision 2023/014/R

LINK BETWEEN DESIGN AND PRODUCTION

In accordance with [AMC1 21.A.122](#_DxCrossRefBm1649097113) the person producing or
intending to
produce under Part 21 Subpart F should demonstrate to the
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 person producing or intending to
produce under Part 21 Subpart F to
demonstrate compliance with the requirement of [21.A.122](#_DxCrossRefBm1649096913) by means of written documents
agreed.

In the
case where the design organisation and the person producing or intending to
produce under Part 21 Subpart F 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:

Instructions
for completion:

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.122](#_DxCrossRefBm1649096913).

Commitment:
The document must include the basic commitments between the design
organisation and the manufacturer producing under Part 21 Subpart F
as addressed in [AMC 21.A.4](#_DxCrossRefBm1649096914)
and [AMC1 21.A.122](#_DxCrossRefBm1649097113).

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 approved design data: Identify
the relevant procedures for the transfer of the applicable design data
required by [21.A.122](#_DxCrossRefBm1649096913) and [AMC1 21.A.122](#_DxCrossRefBm1649097113) from the design
organisation to the person producing under Part 21 Subpart F. The means by
which the design organisation advises the person producing under Part 21
Subpart F 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 person producing
under Part 21 Subpart F 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 organisation is involved in the chain between
the original design organisation and the person producing under Part 21
Subpart F, evidence must be available that this intermediate organisation has
received authority from the design organisation to grant Direct Delivery
Authorisation.

Signature:
[AMC1 21.A.122](#_DxCrossRefBm1649097113)
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 manufacturer producing under Part 21 Subpart F in this
regard.
