AMC1 21L.B.251(b) Oversight ED Decision 2023/013/R FIRST-ARTICLE INSPECTION FOR A NEW AIRCRAFT, ENGINE, PROPELLER OR PART PRODUCED FOR THE FIRST TIME (a)     Purpose The purpose of first-article inspection when a new aircraft, engine, propeller or part is produced and released for the first time is for the competent authority to: (1)     ensure the conformity of the aircraft, engine, propeller or part with the applicable design data; (2)     conduct an oversight visit to the natural or legal person that uses Subpart R in order to ensure that the natural or legal is capable of consistently producing, or controlling the production of, aircraft, products and parts that conform with the declared design data; (3)     ensure that the natural or legal person that uses Subpart R is able to discharge its obligations and responsibilities for production. (b)     Methodology and evidence The first-article inspection should be conducted by the competent authority at an appropriate location(s) selected by the natural or legal person that uses Subpart R. This (these) location(s) should: (1)     be at the physical location of the aircraft, engine, propeller or part under inspection; (2)     be in the principal place of business (which in accordance with [Article 8](#_DxCrossRefBm1649096867)(2) of Regulation (EU) No 748/2012 must be in an EU Member State); and (3)     be in a location that enables the competent authority to conduct the oversight stated in points (a)(2) and (3) above; this location should include the actual production and manufacture of new aircraft, engine, propeller or parts of the aircraft to enable the competent authority to determine that the legal or natural person is in compliance with Subpart R. Note: The principal place of business is defined as follows: ‘The head office or registered office of the organisation within which the principal financial functions and operational control of the activities referred to in this Regulation are exercised.’ The main focus of the activities to gather evidence to ensure the objectives mentioned in point (a) are satisfied should be through a physical inspection of the aircraft for which a statement of conformity has been issued or the engine, propeller or part for which an authorised release certificate has been issued. Additional sources of evidence during the visit to the production organisation’s facilities may include: (1)     the review of supporting conformity documentation and test reports; (2)     the review of applicable design data and how it is used; (3)     discussions with key production personnel; (4)     the review of production processes and procedures. The above list of additional sources of evidence is not exhaustive. It is possible that during the first-article inspection the competent authority may discover ‘evidence’ that indicates that the production organisation has: (1)     misunderstood, misinterpreted or not achieved conformity with the applicable design data; (2)     not discharged its production obligations; (3)     not followed good production practices to ensure conformity or control of a product or part it has produced. If such ‘evidence’ is discovered, the competent authority may perform a more in-depth investigation into the production practices of the production organisation to determine the root cause(s) and to establish corrective actions to prevent a reoccurrence of the issue. (c)      Condition and conformity of the aircraft, engine, propeller or part to be inspected The aircraft, engine, propeller or part presented to the competent authority for inspection should be in the final condition for release and in conformity with the applicable design data. (d)     Availability of supporting documentation and key personnel The supporting documentation and conformity data should be made available by the natural or legal person that uses Subpart R at the time of the visit by the competent authority to the facilities of the production organisation. Key production personnel should be made available to the competent authority in case of need. (e)     Findings and resolution If a non-compliance is discovered by the competent authority in the process of the activities mentioned in point (a), an appropriate finding may be raised. Depending upon its nature, such finding may need to be resolved before the initial and subsequent aircraft, engine(s), propeller(s) or part(s) can be released. (f)      Duration and schedule First-article inspection relating to the initial declaration of design compliance for an aircraft (including engines and propellers). The natural or legal person that uses Subpart R should coordinate with the competent authority so that the first-article-inspection activities to be conducted under point [21L.B.251](#_DxCrossRefBm1649097780)(b) are conducted at the same time as the first-article-inspection activities conducted under point [21L.B.62](#_DxCrossRefBm1649097863)(b). If this is not appropriate (due to the fact that a partial first-article inspection would be beneficial at an earlier stage of production), then it is possible that the declarant arrange this with the competent authority. Note: For a modified or repaired product, when determined under points [21L.B.121](#_DxCrossRefBm1649097965)(b) or [21L.B.221](#_DxCrossRefBm1649098132)(b) respectively, EASA may require and coordinate with the competent authority on the need for a first-article inspection. First-article inspection relating to a part that is produced for the first time by the production organisation For the first-article inspection of every part that is produced for the first time by the natural or legal person that uses Subpart R, it is possible that this is arranged without the need for coordination with EASA. If such a part relates to a major change/repair for which EASA has determined the need for a first-article inspection under points [21L.B.121](#_DxCrossRefBm1649097965)(b) or [21L.B.221](#_DxCrossRefBm1649098132)(b), then EASA may require and coordinate with the competent authority on the need for a first-article inspection. ##### AMC1 21L.B.251(b) Oversight *ED Decision 2023/013/R* **FIRST-ARTICLE INSPECTION FOR A NEW AIRCRAFT, ENGINE, PROPELLER OR PART PRODUCED FOR THE FIRST TIME** (a) Purpose The purpose of first-article inspection when a new aircraft, engine, propeller or part is produced and released for the first time is for the competent authority to: (1) ensure the conformity of the aircraft, engine, propeller or part with the applicable design data; (2) conduct an oversight visit to the natural or legal person that uses Subpart R in order to ensure that the natural or legal is capable of consistently producing, or controlling the production of, aircraft, products and parts that conform with the declared design data; (3) ensure that the natural or legal person that uses Subpart R is able to discharge its obligations and responsibilities for production.
