21.A.7 Instructions for continued airworthiness
(a) The holder of a type-certificate, restricted type-certificate, or supplemental type-certificate, design change or repair design approval must develop or reference the instructions which are necessary for ensuring that the airworthiness standard related to the product and any associated part is maintained throughout the operational life of the product, when demonstrating compliance with the applicable type-certification basis established and notified by the CAA in accordance with point 21.B.80.

(3) a repair design approval to all known operators of the product affected by the repair upon the release to service of the product in which the repair design is embodied. The repaired product, part or appliance may, if the CAA agrees, be released into service before the related instructions for continued airworthiness have been completed, but this must be for a limited service period agreed by the CAA.
