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

23.5.2023	EN	Official Journal of the European Union	L 135/53

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 ¹, and in particular Article 17(1) thereof,

Whereas:

• (1) Commission Regulation (EU) No 1321/2014 ² 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in Article 3, point (j), of Regulation (EC) No 216/2008 of the European Parliament and of the Council ³, and was repealed by Regulation (EU) 2018/1139.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 ⁴ 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 ⁵ 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 ⁶.

• (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.

• (11) The measures provided for in this Regulation are in accordance with the opinion of the committee established by Article 127 of Regulation (EU) 2018/1139,

• ‘3. Basic training methods

An appropriate training method, or combination of methods, shall be determined for the entire course or for each of its modules or submodules, with regard to the scope and objectives of each training phase and taking into consideration the benefits and limitations of the available training methods.

Multimedia-based training (MBT) methods may be used in order to achieve the training objectives either in a physically or in a virtually controlled environment.’;

• (20) Appendix II is amended as follows:

• (a) point 1.4 is replaced by the following:

• ‘1.4. Suitable essay questions shall be drafted and evaluated using the knowledge syllabus in Appendix I Module 7.’;

• (b) points 1.11, 1.12 and 1.13 are replaced by the following:

• ‘1.11 An examination in a module may not be retaken earlier than 90 days following the date of a failed examination in that module, except in the case of a maintenance training organisation approved in accordance with Annex IV (Part-147) which delivers a course of retraining tailored to the failed subjects in the particular module; the failed module may be retaken after 30 days.

• 1.12. Basic knowledge examinations with a maximum allowed time of more than 90 or more than 180 minutes may be split in two or three partial exams respectively.

Each partial exam shall:

• (a) be complementary to the other partial exam or exams taken by the candidate, ensuring that the combination of partial exams meets the examination requirements for the subject module;

• (b) be of similar allowed time;

• (c) be passed with 75 % or more of the questions answered correctly;

• (d) contain a number of questions that is multiple of four;

• (e) be listed on the same certificate of recognition issued after the last partial exam has been successfully passed. That certificate of recognition shall list the dates and the results of the partial exams – without averaging the results;

• (f) be taken within the same organisation, following the normal examination provisions for retaking failed exams.

• 1.13. The maximum number of attempts for each examination is three in a 12-month period.

The applicant shall provide in a written statement to the approved maintenance training organisation or the competent authority to which they apply for an examination, the number, and dates of attempts during the 12 months preceding the examination, and the organisation or the competent authority where those attempts took place. The approved maintenance training organisation or the competent authority is responsible for checking the number of attempts within the applicable time frames.’;

• (c) the following point 1.14 is added:

• ‘1.14 While it is accepted that the subject matter of the questions may be the same, the questions used as part of the MBT learning programme shall not be used in examinations.’;

The designated assessor(s) conducting the final assessment shall notify the date of the assessment to the licensing authority well in advance to allow a possible participation of the same authority.

The objective of the final assessment is to verify that the applicant has sufficient technical knowledge as well as the appropriate skills and attitude and that he or she is competent to work independently as type-rated certifying staff on a particular aircraft type.

The final assessment shall have a minimum duration of one working day.

• (a) The assessment shall sample:

• (1) the general technical knowledge required for the particular licence category;

• (2) the aircraft-type-specific knowledge and skills for the particular licence category;
