21L.B.83 Investigation of a major change to a type certificate

Regulation (EU) 2022/1358

Upon receiving an application for a major change
to a type certificate under this Annex, the Agency shall:

(a)     conduct
a review of the initial compliance demonstration plan and any subsequent
update provided by the applicant in order to establish the completeness of the
plan and the appropriateness of the proposed means and methods of
demonstrating compliance with the type-certification basis and the applicable
environmental protection requirements established and designated in accordance
with point [21L.B.81](#_DxCrossRefBm1649097886); if the compliance
demonstration plan is incomplete or the means and methods are not appropriate
to achieve compliance demonstration, the Agency shall inform the applicant and
request an amendment of it;

(b)     when
satisfied that the compliance demonstration plan provided
is appropriate so that the applicant can demonstrate compliance, approve the
compliance demonstration plan and also approve any subsequent updates of the
compliance demonstration plan;

(c)      determine
the likelihood of an unidentified non-compliance of the major change with the
type-certification basis or with the applicable environmental protection
requirements, and the potential impact of that non-compliance on the safety or
environmental compatibility of the product, and determine on that basis
whether a physical inspection and assessment of the first article of that
product in the final changed configuration is necessary in order to verify the
compliance of the product with the applicable type-certification basis and the
applicable environmental protection requirements, taking into consideration
the critical design review if carried out in accordance with point (a)(3) of
point [21L.B.242](#_DxCrossRefBm1649097844); the Agency shall
notify the applicant before conducting this inspection and assessment;

(d)     if
during the establishment of the type-certification basis, the designation of
the applicable environmental protection requirements or during the review of
the compliance demonstration plan, the Agency determines that the design of
the major change contains any element for which an unidentified non-compliance
with the type-certification basis or the applicable environmental protection
requirements may have an adverse impact on the safety or environmental
compatibility of the changed product, the Agency shall determine which
investigations are necessary in addition to those of point (c) in order to
verify the compliance demonstration; the Agency shall notify the applicant of
those additional investigations and which elements of the design would be subject
to investigation.
