21L.A.209Approval of a repair design under a privilege

(a)The approval of a repair design that it has designed may be issued by an approved design organisation without an application according to point 21L.A.205 in accordance with the scope of its privileges provided for in points (2) and (5) of point 21.A.263(c) of Annex I (Part 21) instead of the Agency, as recorded in the terms of approval.

(b)When issuing a repair approval in accordance with point (a), the design organisation shall:

1.ensure that all the substantiation data and justifications are available;

2.ensure that the compliance of the change with the type-certification basis and the applicable environmental protection requirements according to point (a)of point 21L.A.207 or point (a) of point 21L.A.208 has been demonstrated and declared in accordance with point 21L.A.206;

3.confirm that it has not found:

(i)any non-compliances with the type-certification basis or, where applicable, with the applicable environmental protection requirements, or with the certification specifications chosen;

REPAIR DESIGN APPROVAL BY A DESIGN ORGANISATION APPROVAL (DOA) HOLDER

(a)Approval by a DOA holder The approval of repairs through the use of procedures agreed with EASA implies that the DOA holder issues the approval without EASA’s involvement. EASA will monitor the application of this procedure within the surveillance plan for the relevant organisation. When the organisation exercises this privilege, the repair release documentation should clearly show that the approval is issued on the basis of its privilege.

(b)Previously approved data for other applications When it is intended to use previously approved data for other applications, it is expected that an appropriately approved design organisation has checked the applicability and effectiveness of this data. After damage identification, if a repair solution exists in the available approved data, and if the application of this solution to the identified damage remains justified by the previously approved repair design (structural justifications still valid, possible airworthiness limitations unchanged), the solution may be considered approved and may be used again.

(c)Temporary repairs These are life-limited repairs to be removed and replaced by permanent repairs after a limited service period. These repairs should be classified under point 21L.A.203, and the service period should be defined when the temporary repair is approved.

(d)Fatigue and damage tolerance An approved design issued before the fatigue- and damage-tolerance evaluation has been completed should specify the limited service period.
