CONFORMITY OF PROTOTYPE MODELS AND TEST SPECIMENS Points 21L.A.25(c) and 21L.A.44(d) require the determination of conformity of prototype models and test specimens to the applicable design data. The EASA Form 1 may be used as a conformity certificate as part of the assistance that a declared production organisation provides to a design approval holder/applicant or a declarant of a declaration of design compliance. The EASA Form 1 should only be used for conformity release purposes when it is possible to indicate (in Block 12) the reason that prevents its issuance for airworthiness release purposes.

FLIGHT CONDITIONS The need to recommend flight conditions for an aircraft is related to the performance of the production flight tests. Production flight tests of a newly manufactured aircraft should be performed under the conditions specified in point 21L.A.241 and under Subpart P of Annex I (Part 21) to this Regulation. For this purpose, the declared production organisation should apply for a permit to fly to the competent authority. EASA Form 21 (see AMC 21.B.520(b)) should be obtained from the competent authority. Where the flight conditions are not approved at the time of application for a permit to fly, the declared production organisation should also apply for approval of the flight conditions (refer to point 21L.A.241(a) (and by inference to point 21.A.709 of Annex I (Part 21))).
