Article 25 Issue, renewal and validity of certificate of airworthinessI1
United Kingdom
The Governor must issue a certificate of airworthiness for any aircraft upon being satisfied that the specified requirements have been complied with and on being satisfied that the aircraft is fit to fly having regard to—
the design, construction, workmanship and materials of the aircraft, including in particular any engines fitted in the aircraft, and of any equipment carried in the aircraft which is necessary for the airworthiness of the aircraft;
the results of flying trials, and such other tests of the aircraft as the Governor may require; and
subject to paragraph (2), the issue of a certificate of release to service under and in accordance with the provisions of article 32.
A certificate of release to service is not required in respect only of the re-issue of a certificate of airworthiness under paragraph (1).
Nothing in this Order obliges the Governor to accept an application for the issue of a certificate of airworthiness or for the variation or re-issue of any such certificate when the application is not supported by such reports from such persons as the Governor may specify (either generally or in a particular case or class of cases).
