Commission Implementing Regulation (EU) 2023/989 of 22 May 2023 amending Regulation (EU) No 1321/2014 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks, and correcting that Regulation

Commission Implementing Regulation (EU) 2023/989 of 22 May 2023 amending Regulation (EU) No 1321/2014 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks, and correcting that Regulation THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations (EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91 OJ L 212, 22.8.2018, p. 1. , and in particular Article 17(1) thereof, Whereas: (1) Commission Regulation (EU) No 1321/2014 Commission Regulation (EU) No 1321/2014 of 26 November 2014 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks (OJ L 362, 17.12.2014, p. 1). lays down the requirements for the continuing airworthiness of aircraft, including the qualifications and licences of the personnel responsible for the release to service of products after maintenance. (2) The term complex motor-powered aircraft had been defined in Article 3, point (j), of Regulation (EC) No 216/2008 of the European Parliament and of the Council Regulation (EC) No 216/2008 of the European Parliament and of the Council of 20 February 2008 on common rules in the field of civil aviation and establishing a European Aviation Safety Agency, and repealing Council Directive 91/670/EEC, Regulation (EC) No 1592/2002 and Directive 2004/36/EC (OJ L 79, 19.3.2008, p. 1). , and was repealed by Regulation (EU) 2018/1139. In accordance with Article 140(2), point (b), of Regulation (EU) 2018/1139, Regulation (EU) No 1321/2014 is to be adapted to Regulation (EU) 2018/1139 as regards the definition of that term. (3) In order to enhance the efficiency of the maintenance licencing and training system, it is necessary to introduce changes to the requirements on maintenance licences and training organisations set out in Annex III (Part-66) and Annex IV (Part-147) to Regulation (EU) No 1321/2014. (4) In particular, it is necessary to facilitate the type rating endorsement of aircraft on the maintenance licenses when there are no organisations approved in accordance with Annex IV to Regulation (EU) No 1321/2014 offering type training on that aircraft, maintaining the same level of safety and a level playing field. It is also necessary to update the basic training syllabus of the certifying staff involved in the aircraft maintenance, enhance the efficiency of the on-the-job training required for the first type rating endorsement in the maintenance licence category and to introduce new training methods and teaching technologies and other improvements as part of the regular update of the rules in that Annex.

(5) Regulation (EU) No 1321/2014 should therefore be amended accordingly. (6) The amendments are based on Opinion No 07/2022 https://www.easa.europa.eu/document-library/opinions of the European Union Aviation Safety Agency in accordance with Article 75(2), point (b), and Article 76(1) of Regulation (EU) 2018/1139. (7) A sufficient transition period should be provided for maintenance training organisations and licencing authorities to ensure their compliance with the new rules and procedures introduced by this Regulation. (8) Commission Implementing Regulation (EU) 2022/1360 Commission Implementing Regulation (EU) 2022/1360 of 28 July 2022 amending Regulation (EU) No 1321/2014 as regards the implementation of more proportionate requirements for aircraft used for sport and recreational aviation (OJ L 205, 5.8.2022, p. 115). amended Regulation (EU) No 1321/2014 to include references to data and information used for continuing airworthiness established in accordance with the new Annex Ib to Commission Regulation (EU) No 748/2012 Commission Regulation (EU) No 748/2012 of 3 August 2012 laying down implementing rules for the airworthiness and environmental certification of aircraft and related products, parts and appliances, as well as for the certification of design and production organisations (OJ L 224, 21.8.2012, p. 1). . (9) Implementing Regulation (EU) 2022/1360 inadvertently deleted point (3) of point M.A.302(d) of Annex I (Part-M) to Regulation (EU) No 1321/2014 and points (3) to (9) of point ML.A.302(c) of Annex Vb (Part-ML) to that Regulation, which should have been retained. Implementing Regulation (EU) 2022/1360 also inadvertently added another point (e) to point M.A.502 of Annex I (Part-M) to Regulation (EU) No 1321/2014 instead of replacing it. (10) Regulation (EU) No 1321/2014 should therefore be corrected accordingly.

Basic knowledge modules or partial modules required

The purpose of this table is to outline the examinations required to add a new basic category/subcategory to an AML granted in accordance with this Annex. The syllabi prepared in accordance with Appendix I and Appendix VII require different levels of knowledge for different licence categories within a module; therefore, there are additional examinations applicable to certain modules for licence holders wishing to extend an AML granted in accordance with this Annex to include another category/subcategory and an analysis of the module shall be conducted to determine the subjects missing or passed at a lower level.

Appendix IX Assessment method for the multimedia-based training (MBT)

1. The purpose of this Appendix is to establish the requirements for the assessment and approval by a competent authority of any course that includes MBT in accordance with point 66.B.135. This Appendix may be used for the assessment of other training courses if the competent authority decides that the assessment method laid down in this Appendix are appropriate for such other courses. The assessment shall be conducted by the competent authority against all the criteria laid down in Table (A), grouped in four categories from (a) to (d). The competent authority shall clearly identify in the table the MBT product being assessed and its production and update versions.
2. The competent authority carrying out the assessment shall put itself in the position of the student or the end user and shall rate each criterion listed in Table (A) individually on a rating scale from 1 to 5, as follows: 1: Not acceptable. Does not meet the required criteria. 2: Partially acceptable, but improvement is needed to meet the required criteria.

3: Acceptable. Meets the required criteria. 4: Good. Meets the required criteria with enhancements made. 5: Excellent. Exceeds the required criteria. 3. If one or more of the criteria is rated below 3, an alternative learning process shall be requested by the competent authority in order to enhance the suitability of the product to an acceptable level. 4. Once the competent authority has rated each of the individual criteria listed in Table (A), the following combined rating scale shall be used by the competent authority to determine the overall suitability level for each MBT learning resource: 100–80: Excellent learning resource. It offers different functionalities and meets the required suitability criteria. 79–60: The learning resource meets the required suitability criteria. 59–40: The learning resource does not allow for a sufficiently worthy educational use. It can be used for informal training only. 39–20: The learning resource is below the average. It does not meet several required suitability criteria. Before approving the product, the competent authority shall check that the final score of the MBT is equal to or above 60, and that there is no single criterion that is rated below 3. Table (A): Assessment for the multimedia-based training (MBT) Notes: The following shall be taken into account by the competent authority when assessing the MBT against the individual criteria listed in Table (A): Categories: Assessment table for the multimedia-based training (MBT)Product identification:Name:Version:SCORE (1–5)Category (a) academic qualityInformation reliability

Final score: (a) Academic quality The information presented in the multimedia resource shall have two characteristics: i. Reliability: the information is reliable, current, and relatively free of errors. The information complies with the current regulatory requirements. ii. Relevance: the information is relevant to the learning objectives defined for the course. It supports the student in achieving the learning objectives. (b) Pedagogical quality The MBT emphasises the activities which promote the development of the required knowledge and skills. The main criteria for each product are related to three aspects: i. Pedagogical formulation/construction: it is characterised by the quality of simplification, the presence of summaries as well as the use of diagrams, figures, animations, and illustrations. It evaluates whether the structure of the learning resource promotes its use in a pedagogical context. This refers to the ease of orientation (summary, lesson plan), presence of appropriate interactions, usability (back, forward, scroll boxes, etc.), and communication resources (questions and answers, FAQs, forum, etc.) ii.
