GM1 to 21L.A.127(c) Obligations of the declared production organisation

CONFORMITY WITH APPROVED OR DECLARED DESIGN DATA Individual configurations are often based on the needs of the customer and improvements or changes which may be introduced by the type-certificate holder or the declarant of a declaration of design compliance. There are also likely to be unintentional deviations (concessions or non-conformances) during the manufacturing process. All these changes should be subject to approval by the design approval holder or the declarant, as relevant, or, when necessary, by EASA.
