Where there is a need to provide (normally outside the design organisation) a visible statement of approved design data or airworthiness, operational suitability or environmental protection data associated with the approved design data, the following minimum information must be provided. The need for a visible statement may be in relation to Company holding a production organisation approval (POA) in relation to 21.A.163(c). The procedures related to the use of forms or other electronic means to provide this information must be agreed with the Agency. Information to be provided: Company Name: the name of the responsible design organisation (TC, STC, approval of repair or minor change design, ETSO authorisation holder) issuing the information. Date: the date at which the information is released. Eligibility: indicate the specific products or articles, in case of ETSO authorisation, for which data have been approved. Identification: the part number of the part or appliance. Preference should be given to the use of the Illustrated Parts Catalogue (IPC) designation. Alternatively the reference to the instruction for continued airworthiness (e.g., SB, AMM, etc.) could be stated. Marking requirements of Part 21 Section A Subpart Q should be taken into account. Description: the name or description of the part or document should be given. In the case of a part or appliance preference should be given to use of IPC designation. The description is to include reference to any applicable ETSO authorisation or EPA marking, or previous national approvals still valid. Purpose of data: the reason for the provision of the information should be stated by the design approval holder. Examples: a) Provision of approved design data to a production organisation to permit manufacture (AMC No 1 to 21.A.133(b) and (c)) b) Information regarding eligibility for installation (replacement parts, repair, modification, etc.) c) Direct Delivery Authorisation (AMC No 1 to 21.A.133(b) and (c)) If the data is in support of a change or repair, then reference to the aircraft level approval should be given (make reference to the approved STC, change or repair). Limitations/Remarks: state any information, either directly or by reference to supporting documentation that identifies any particular data or limitations (including specific importing requirements) needed by a production organisation to complete Block 12 of the EASA Form 1. Approval: provide reference information related to the approval of the data (Agency document or DOA privilege). Authorised signature: name and hand-written normal or electronic signature of a person who has written authority from the design organisation, as indicated in the procedures agreed with the Agency.
