GM1 21L.A.174(d) Management system for design

DOCUMENTATION

Point 21L.A.174(d) requires the declared design organisation to document its processes and procedures.

In order to do so, the declared design organisation may consider to establish a declared design organisation exposition (DDOE). The purpose of a DDOE is to set forth in a concise document format the organisational relationships, responsibilities, terms of reference, and the associated authority, procedures, means and methods of the organisation.

If utilised, the DDOE typically contains the following:

(a) a statement signed by the head of the design organisation confirming that the DDOE and any associated manuals, procedures and instructions that define the organisation’s compliance with this Subpart will be complied with at all times;

(b) the title(s) and name(s) of the person(s) nominated in accordance with point 21L.A.175(b);

(c) the duties and responsibilities of the head of the design organisation and the person(s) as specified by point 21L.A.175(b), including matters on which they may deal directly with EASA on behalf of the organisation;

(d) an organisational chart showing the associated chains of responsibility of the managers as required by point 21L.A.175(e);

(e) the list of authorised staff that perform the independent function of verifying the demonstration of compliance as referred to in point 21L.A.174(b)(2);

(f) the nomination procedure for key personnel and authorised staff;

(g) a general description of manpower;

(h) a general description of the facilities located at each address specified in the declaration of design capability;

(i) a general description of the declared design organisation’s scope of work as defined in the declaration of design capability (see also point 21L.A.176);

(j) the procedure for the notification of organisational changes to EASA according to point 21L.A.178;

(k) the procedure for the amendment of the DDOE;

(l) the independent system monitoring procedure;

(m) the subcontracting procedure and the list of partners and subcontractors;

(n) the procedure for identification and issuance of type design documentation and configuration control;

(o) the procedure(s) followed and forms used for type certification and supplemental type certification;

(p) the procedures for design changes;

(q) the procedure for design of repairs;

(r) the continued-airworthiness procedures (including reporting system and data in support of the issuance of airworthiness directives);

(s) the procedures for the collaboration between design and production organisations (including transfer of design data and approval of production concessions or non-conformities);

(t) the record-keeping procedure;

(u) the procedure for marking products and parts;

(v) the procedures for the issuance of manuals and instructions for continued airworthiness (ICAs);

(w) the procedures for the interface with EASA (supporting EASA investigations and answering to findings and observations).

The DDOE may be produced and distributed in paper or electronic format. If the above information is documented in separate procedures and instructions, the DDOE may include a summary of the information and an appropriate cross reference.

When changes to the organisation occur, the DDOE should be kept up to date. Changes to the organisation shall be notified to EASA as required by point 21L.A.178.

If the organisation holds one or more additional organisation certificates within the scope of Regulation (EU) 2018/1139 and the delegated and implementing acts that are adopted on the basis thereof (DOA, POA, etc.), so that the organisation is required to establish another exposition, the organisation may combine the documents by producing a separate manual or supplement that covers the differences between the DDOE and the other exposition. In that case, the manual or supplement should identify where in the other exposition the remaining information on the declared design organisation is covered. That remaining information then formally becomes part of the exposition.
