GM1 21L.2Competent authority
RESPONSIBILITY FOR IMPLEMENTATION Each certificate or registration of a declaration of capability in accordance with Part 21 Light Section A Subparts G, H, I, P and R is normally issued and overseen by the competent authority of the Member State in which the natural or legal person is located. Therefore, to ensure consistency between the competent authorities of the Member States in issuing certificates and registering declarations of capability, the implementation of Part 21 Light should be based on the following three principles:
(a)The establishment and maintenance of an effective organisation and the corresponding processes by all competent authorities.
(b)The operation of all the competent authorities in accordance with Part 21 Light and the acceptable means of compliance (AMC) and guidance material (GM) thereto; and
(c)A standardisation process that is established and applied by EASA to assess the standard(s) achieved, and to provide timely advice and guidance to the competent authorities. As a result, the responsibility for implementation consists of two main objectives:
(d)to ensure that certificates and registration of declarations of capability are only granted to natural or legal persons that comply with the requirements of Part 21 Light; and
(e)to ensure that there is sufficient visibility of the processes to give the Agency and the Member States the necessary confidence in the certificates granted or the capability of natural or legal persons that have a registered declaration of design or production capability or use Subpart R for production.
