[F54 The derogation in point (b) does not apply to large aeroplanes subject to point 26.300 of Annex I to Commission Regulation (EU) 2015/640(1). For those large aeroplanes, the applicant must comply with certification specifications that provide at least an equivalent level of safety to points 26.300 and 26.330 of Annex I to Regulation (EU) 2015/640, except for applicants for supplemental type-certificates who are not required to take into account point 26.303.]

However, if the [F53 CAA] finds that the change is significant in an area, the [F53 CAA] may require that the change and areas affected by the change comply with an amendment to a certification specification of the type-certification basis incorporated by reference in the type-certificate and with any other certification specification which is directly related, unless the [F53 CAA] also finds that compliance with that amendment does not contribute materially to the level of safety of the changed product or is impractical.

(d)

If the [F53 CAA] finds that the certification specifications applicable on the date of the application for the change do not provide adequate standards with respect to the proposed change, the change and areas affected by the change shall also comply with any special conditions, and amendments to those special conditions, prescribed by the [F53 CAA] in accordance with point 21.B.75, to provide a level of safety equivalent to that established by the certification specifications applicable on the date of the application for the change.

(e)

By derogation from points (a), (b) and (c), the change and areas affected by the change may comply with an alternative to a certification specification designated by the [F53 CAA] if proposed by the applicant, provided that the [F53 CAA] finds that the alternative provides a level of safety which is:

1.

in the case of a type-certificate:

(i)

equivalent to that of the certification specifications designated by the [F53 CAA] under (a), (b) or (c) above; or

(ii)

compliant with the essential requirements of Annex II to Regulation (EU) 2018/1139;

2.

in the case of a restricted type-certificate, adequate with regard to the intended use.

(f)

If an applicant chooses to comply with a certification specification set out in an amendment that becomes applicable after submitting the application for a change to a type-certificate, the change and areas affected by the change shall also comply with any other certification specification which is directly related.

(g)

When the application for a change to a type-certificate for an aircraft includes, or is supplemented after the initial application to include, changes to the operational suitability data, the operational suitability data certification basis shall be established in accordance with points (a)-(f).]
