COMMISSION REGULATION (EU) No 1149/2011

of 21 October 2011

amending Regulation (EC) No 2042/2003 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union, in particular Article 100(2) thereof,

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 Article 5(5) thereof,

Whereas:

(1)

In order to maintain a high uniform level of aviation safety in Europe, it is necessary to introduce changes to the existing requirements and procedures on the continuing airworthiness of aircraft and aeronautical products, parts and appliances and on the approval of organisations and personnel involved in these tasks, in particular in order to update the training, examination, knowledge and experience requirements for the issuance of aircraft maintenance licences and to adapt these requirements to the complexity of the different categories of aircraft.

(2)

Commission Regulation (EC) No 2042/2003 (2) should therefore be amended accordingly.

(3)

The measures provided for in this Regulation are based on the opinions (3) issued by the European Aviation Safety Agency (hereinafter ‘the Agency’) in accordance with Articles 17(2)(b) and 19(1) of Regulation (EC) No 216/2008.

(4)

It is necessary to provide sufficient time for the personnel eligible to the new aircraft maintenance license category B3 introduced by this regulation, the training organisations and the maintenance organisations, as well as to the competent authorities of Member States, to adapt to the new regulatory framework.

(5)

Given the lower complexity of light aircraft, it may be appropriate to define a simple and proportionate system for the licensing of the personnel involved in the maintenance of such aircraft. The Agency should be allowed to continue working on this matter and the Member States to continue using the corresponding national licenses.

(6)

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,

HAS ADOPTED THIS REGULATION:

Article 1

Regulation (EC) No 2042/2003 is amended as follows:

(1)

‘3.   Certifying staff holding a licence issued in accordance with Annex III (Part-66) in a given category/sub-category are deemed to have the privileges described in point 66.A.20(a) of this Annex corresponding to such a category/sub-category. The basic knowledge requirements corresponding to these new privileges shall be deemed as met for the purpose of extending such licence to a new category/sub-category.

4.   Certifying staff holding a licence including aircraft which do not require an individual type rating may continue to exercise his/her privileges until the first renewal or change, where the licence shall be converted following the procedure described in point 66.B.125 of Annex III (Part-66) to the ratings defined in point 66.A.45 of this Annex.

5.   Conversion reports and Examination credit reports complying with the requirements applicable before this Regulation applies shall be deemed to be in compliance with this Regulation.

6.   Until such time as this Regulation specifies requirements for certifying staff:

(i)

4.   Basic knowledge examinations complying with the requirements applicable before this Regulation applies and conducted by the competent authority or conducted by a maintenance training organisation approved in accordance with Annex IV (Part-147) while not being part of a basic training course, may be conducted until 1 year after the date by which this Regulation applies.

5.   Type training courses and type examinations complying with the requirements applicable before this Regulation applies shall be started and finished not later than 1 year after the date by which this Regulation applies.’;
