four-fifths of the height of the basket ; and
(b) The height of the other marks shall be equal to at least one-fifteenth of

for a non-spherical balloon equal to at least one-twelfth of the
circumference at the maximum cross-section.

subparagraphs, the nationality and registration marks on any aircraft need not
exceed 8 ft. in height.

Width and Thickness of Letters in Marks, &c.

10. (1) The width of letters in a mark shall be two-thirds of their height,

SECTION I.—ISSUE OF CERTIFICATES OF AIRWORTHINESS.

1. Subject to paragraph 3 the Minister may issue to a constructor of aircraft
   a certificate of airworthiness in respect of one aircraft of any type (in this Schedule
   referred to as a “ type aircraft ”).

2. Upon the issue of a certificate under the last preceding paragraph, any
   other aircraft of that type constructed by the constructor shall be inspected
   under arrangements approved by the Minister, and if the aircraft conforms in all
   essential respects with the type aircraft and is of satisfactory workmanship and
   materials, the Minister may issue a certificate of airworthiness in respect of the
   aircraft.

3. A certificate of airworthiness shall not be issued unless—
   (a) The design of the aircraft in regard to safety conforms to certain minimum
   requirements approved by the Minister.
   (b) A satisfactory demonstration is made in flying trials of the actual flying
   qualities of the type of aircraft examined provided that machines
   subsequently manufactured need not be subject to such trials. The
   trials shall conform to certain minimum requirements approved by
   the Minister.
   (c) The construction of every aircraft with regard to workmanship and
   materials is approved by the Minister. The control of the construction
   and of the tests shall be in accordance with certain minimum require-
   ments.

4. An application for a certificate of airworthiness should be made at a very
   early stage in the design of an aircraft, addressed to the Controller of Civil Aviation,
   Defence, Wellington.

Validation and Renewal of Certificates of Airworthiness.

5. Applications for the validation and renewal of certificates of airworthiness
   should be made to the Controller of Civil Aviation, Defence, Wellington, by whom
   application forms will be supplied on demand.

6. Except in the case of aircraft designed and constructed in New Zealand
   when an aircraft registered in New Zealand in respect of which a certificate of
   airworthiness has been granted by the duly competent authority in Great Britain
   or in any other part of His Majesty’s dominions or in any contracting State, and
   provided such certificate is in force at or immediately prior to the time of
   registration of the aircraft in New Zealand, the Minister may, subject to con-
   siderations of public safety, and for a reasonable period, confer on such certificate
   the same validity as if it had been granted under these regulations.
