Show the text

It is the responsibility of the natural or legal person that produce under Subpart R to ensure that each and every product and part conforms with the applicable design data and is in a condition for safe operation before issuing and signing the relevant statement of conformity (EASA Form 52B) or authorised release certificate (EASA Form 1). During manufacture, the natural or legal person is expected to use the facilities, systems, processes and procedures it has established for fulfilling its obligations under points 21L.A.273 and 21L.A.275. The competent authority should then inspect and investigate the records, products or parts that are necessary to be satisfied that the aircraft is in conformity with the design for which the design compliance has been declared (see points 21L.B.143 and 21L.B.144). To enable timely inspection and investigation by the competent authority, the statement of conformity should be prepared and submitted to the competent authority immediately upon the satisfactory completion of the final production inspection and test.
