IRImplementing rule

21.B.107Issuance of an approval of a change to a type-certificate

(a)The Agency shall issue an approval of a change to a type-certificate provided that:

1.the applicant for an approval has complied with:

(i)point 21.A.95 for a minor change; or

(ii)point 21.A.97 for a major change;

2.the Agency, through verification of the demonstration of compliance in accordance with the level of its involvement established on the basis of point 21.B.100(a) or (b) has not found any non-compliance with the applicable type-certification basis, operational suitability data certification basis, where applicable, in accordance with point 21.B.82, and the applicable environmental protection requirements; and

3.no feature or characteristic has been identified that may render the product, the UAS or the CMU unsafe for the use for which certification is requested.

(b)In the case of a change that affects the operational suitability data, by way of derogation from points 1 and 2 of point (a), at the applicant’s request included in the declaration referred to in point 21.A.20(d), the Agency may approve a change to an aircraft type-certificate before compliance with the applicable operational suitability data certification basis has been demonstrated, provided that the applicant demonstrates such compliance before the date on which this data is to be actually used.

(c)The approval of the changes to the operational suitability data shall be included in the approval of the change to the type-certificate.

(d)The approval of a change to a type-certificate shall be limited to the specific configuration(s) in the type-certificate to which the change relates.

GM 21.B.107and 21.B.111 Operational suitability data (OSD) considerations for the approval of changes to type certificates (TCs) or supplemental type certificates (STCs)

Show the text

The requirement for EASA in points 21.B.107(c) or 21.B.111(c) are applicable to necessary changes to the OSD as foreseen by 21.A.95(b) Section 2 for minor changes, 21.A.97(b) Section 2 for major changes, and 21.A.115(b) Section 3 for STCs. By analogy, these requirements should also be considered by design organisation approval (DOA) holders that approve changes or issue supplemental type certificates (STCs) under their privileges (without EASA’s involvement), as stated in the GM to A.21.A.90A. Changes to TCs can comprise several interrelated changes to the TC. For example, a change to the cockpit design may trigger a necessary change to the flight crew data, which is part of the OSD, and is, therefore, included in the TC. Interrelated changes (e.g. type design changes and necessary changes to the MMEL and/or flight crew data) should be approved together under a single approval.
