COMMISSION REGULATION (EU) 2018/1142

of 14 August 2018

amending Regulation (EU) No 1321/2014 as regards the introduction of certain categories of aircraft maintenance licences, the modification of the acceptance procedure of components from external suppliers and the modification of the maintenance training organisations' privileges

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to 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 (1), and in particular Articles 5(5) and 6(3) thereof,

Whereas:

(1)	Commission Regulation (EU) No 1321/2014 (2) establishes the implementing rules on the continuing airworthiness of aircraft and aeronautical products, parts and appliances and on the approval of organisations and personnel involved in these tasks.

(2)

In order to ensure a high uniform level of aviation safety, there is a need for a system, established at Union level, for the licencing of certifying staff involved in the maintenance of ELA1 aeroplanes and for aircraft other than aeroplanes and helicopters. That system should be simple and proportionate. Therefore, necessary measures should now be taken in order to set up such a system.

(3)

The existing requirements related to a licence for certifying staff involved in the maintenance of avionics and electrical systems of aircraft other than those in the group of complex aircraft are not proportionate to the lower complexity of those aircraft, in particular because a significant amount of basic knowledge requirements are only relevant in relation to complex aircraft. A new licence for such staff should there be introduced. The requirements for that new licence should ensure that the level of safety is not reduced compared to the one achieved with the existing licence. The introduction of that new licence should reduce potential safety risks which could occur as a consequence of insufficient adequately qualified and licensed staff being available for the maintenance tasks concerned.

(4)

During performance of maintenance, it is common that persons or organisations use components, parts or material provided by third parties. It is necessary to mitigate the risks associated to the acceptance of such components, parts or material and, in particular, to ensure that the persons and organisations concerned take the necessary measures to ensure proper acceptance, classification and segregation thereof.

(5)

A significant number of fraud cases, showing a deliberate violation of the examination standards set in accordance with Regulation (EU) No 1321/2014, have been reported to the European Aviation Safety Agency (‘Agency’). Those cases related to basic knowledge examinations performed by approved maintenance training organisations for students who did not attend the basic training course. This situation has led to important safety concerns, in particular in light of the risk of licence holders releasing to service aircraft after maintenance without having the basic knowledge required. Measures should now be taken to address those safety concerns.

(6)

Pursuant to Regulation (EU) No 1321/2014, operators of complex motor-powered aircraft, in commercial or non-commercial operations, are to ensure that the tasks associated with continuing airworthiness are performed by an approved continuing airworthiness management organisation and that the maintenance of the aircraft and components for installation thereon is performed by an approved maintenance organisation. However, in certain cases, such as in the non-commercial operation of lighter twin-turboprop aeroplanes, the compliance effort that is required from such operators is disproportionate to the benefits that implementing those requirements bring to the safety of their operations. The requirements applicable in those cases should therefore be adapted. Considering those disproportionate compliance efforts, the time needed to adapt those requirements and that not applying them in those cases until they have been adapted is not assessed to pose any significant risks to aviation safety, those requirements should cease to apply for the time being and apply only from an appropriate later date.

(7)	Detailed rules regarding the use of Appendix VI of Annex III to Regulation (EU) No 1321/2014 were deleted by mistake when Regulation (EU) No 1321/2014 was amended by Regulation (EU) 2015/1536 (3). That mistake should be corrected.

(8)	Certain editorial errors leading to implementation difficulties have been identified in Annex Va to Regulation (EU) No 1321/2014. Those errors should be corrected.

(9)

It is necessary to provide sufficient time to all parties concerned to adapt to the amended regulatory framework created as a consequence of the measures laid down in this Regulation. Those measures should therefore become applicable six months after the date of its entry into force. However, given their purpose and the absence of a need for any significant efforts to adapt by the parties concerned, certain measures should apply without delay. Certain other measures require more adaptation efforts and should therefore apply from an appropriate later date, however, because they entail the transition from regulation primarily under national law to the amended regulatory framework under Union law laid down in this Regulation.

(10)	Regulation (EU) No 1321/2014 should therefore be amended accordingly.

(11)	The measures provided for in this Regulation are in accordance with opinions of the Agency submitted pursuant to Article 19(1) of Regulation (EC) No 216/2008.

(12)	The measures provided for in this Regulation are in accordance with the opinion of the Committee established by Article 65 of Regulation (EC) No 216/2008,

‘1.	An example of the aircraft maintenance licence referred to in Annex III (Part-66) can be found on the following pages.

The document shall be printed in the standardised form shown but may be reduced in size to allow it being generated by computer. When the size is reduced, care shall be taken to ensure that sufficient space is available in those places where official seals or stamps are required. Computer-generated documents need not have all the boxes incorporated when any such box remains blank, so long as the document can clearly be recognised as an aircraft maintenance licence issued in accordance with Annex III (Part-66).

The document may be filled in either in English or the official language of the Member State of the competent authority. In the latter case, a second copy in English shall be attached to the document for any licence holder who needs to use the licence outside that Member State to ensure understanding for the purpose of mutual recognition.

4.	Each licence holder shall have a unique licence holder number, established on the basis of a national identifier and an alpha-numeric designator.

The document may have the pages in a different order to the one of this example and needs not have some or any divider lines as long as the information contained is positioned in such a manner that each page lay-out can clearly be identified with the format of the example of the aircraft maintenance licence contained herein.

The document shall be prepared by the competent authority. However, it may also be prepared by any maintenance organisation approved in accordance with Annex II (Part-145), where the competent authority agrees to this and the preparation takes place in accordance with a procedure laid down in the maintenance organisation exposition referred to in point 145.A.70 of Annex II (Part-145). In all cases, the competent authority shall issue the document.

The preparation of any change to an existing aircraft maintenance licence shall be carried out by the competent authority. However, it may also be prepared by any maintenance organisation approved in accordance with Annex II (Part- 145), where the competent authority agrees to this and the preparation takes place in accordance with a procedure laid down in the maintenance organisation exposition referred to in point 145.A.70 of Annex II (Part-145). In all cases, the competent authority shall change the document.

The holder of the aircraft maintenance licence shall keep it in good condition and shall ensure that no unauthorised entries are made. Failure to comply with this rule may invalidate the license or lead to the holder not being permitted to hold any certification privilege. It may also result in prosecution under national law.

9.	The aircraft maintenance licence issued in accordance with Annex III (Part-66) shall be recognised in all Member States and it is not required to exchange the document when working in another Member State.

10.	The Annex to EASA Form 26 is optional and may only be used to include national privileges, where such privileges are covered by national law outside the scope of Annex III (Part-66).

11.

With regard to the aircraft type rating page of the aircraft maintenance licence, the competent authority may decide not to issue this page until the first aircraft type rating needs to be endorsed and may need to issue more than one aircraft type rating page depending on the number of type ratings to be listed.

12.	Notwithstanding point 11, each page issued shall be in the format of this example and contain the specified information for that page.

13.	The aircraft maintenance licence shall clearly indicate that the limitations are exclusions from the certification privileges. If there are no limitations applicable, the LIMITATIONS page shall state ‘No limitations’.

14.	Where a pre-printer format is used for issuing the aircraft maintenance licence, any category, subcategory or type rating box which does not contain a rating entry shall be marked to show that the rating is not held.’;
