8—(1) Subject to paragraph (2) an aircraft shall not fly unless there is in force in respect thereof a certificate of airworthiness duly issued or rendered valid under the law of the country in which the aircraft is registered or the State of the operator, and any conditions subject to which the certificate was issued or rendered valid are complied with.
(2) The foregoing prohibition shall not apply to flights, beginning and ending in the United Kingdom without passing over any other country, of:
(a)a glider, if it is not being used for the public transport of passengers or aerial work other than aerial work which consists of the giving of instruction in flying or the conducting of flying tests in a glider owned or operated by a flying club of which the person giving the instruction or conducting the test and the person receiving the instruction or undergoing the test are both members;
(b)a balloon flying on a private flight;
(c)a kite;
(d)an aircraft flying in accordance with the ‘A Conditions’ or the ‘B Conditions’ set forth in Part A of Schedule 3 to this Order; or
(e)an aircraft flying in accordance with the conditions of a permit to fly issued by the CAA in respect of that aircraft.
(3) In the case of an aircraft registered in the United Kingdom the certificate of airworthiness referred to in paragraph (1) shall be a certificate issued or rendered valid in accordance with the provisions of article 9 of this Order.
9—(1) The CAA shall issue in respect of any aircraft a certificate of airworthiness if it is satisfied that the aircraft is fit to fly having regard to:
(a)the design, construction, workmanship and materials of the aircraft (including in particular any engines fitted therein), and of any equipment carried in the aircraft which it considers necessary for the airworthiness of the aircraft; and
(b)(i)subject to sub-paragraph (ii) the results of flying trials, and such other tests of the aircraft as it may require:
(ii)if the CAA has issued a certificate of airworthiness in respect of an aircraft which, in its opinion, is a prototype aircraft or a modification of a prototype aircraft, it may dispense with flying trials in the case of any other aircraft if it is satisfied that it conforms to such prototype or modification.
(2) Every certificate of airworthiness shall specify such categories as are, in the opinion of the CAA, appropriate to the aircraft in accordance with Part B of Schedule 3 to this Order and the certificate shall be issued subject to the condition that the aircraft shall be flown only for the purposes indicated in the said Schedule in relation to those categories.
(3) The CAA may issue the certificate of airworthiness subject to such other conditions relating to the airworthiness of the aircraft as it thinks fit.
(4) The certificate of airworthiness may designate the performance group to which the aircraft belongs for the purposes of the requirements referred to in article 36(1) of this Order.
(5) The CAA may, subject to such conditions as it thinks fit, issue a certificate of validation rendering valid for the purposes of this Order a certificate of airworthiness issued in respect of any aircraft under the law of any country other than the United Kingdom.
(6) Subject to the provisions of this article and of article 81 of this Order, a certificate of airworthiness or validation issued under this article shall remain in force for such period as may be specified therein, and may be renewed from time to time by the CAA for such further period as it thinks fit.
(7) A certificate of airworthiness or a certificate of validation issued in respect of an aircraft shall cease to be in force:
(a)if the aircraft, or such of its equipment as is necessary for the airworthiness of the aircraft, is overhauled, repaired or modified, or if any part of the aircraft or of such equipment is removed or is replaced, otherwise than in a manner and with material of a type approved by the CAA either generally or in relation to a class of aircraft or to the particular aircraft;
(b)until the completion of any inspection or maintenance of the aircraft or of any such equipment as aforesaid, being an inspection made for the purpose of ascertaining whether the aircraft remains airworthy and:
(i)classified as mandatory by the CAA;
(ii)required by a maintenance schedule approved by the CAA in relation to that aircraft; or
(c)until the completion to the satisfaction of the CAA of any modification of the aircraft or of any such equipment as aforesaid, being a modification required by the CAA for the purpose of ensuring that the aircraft remains airworthy.
(8) Nothing in this Order shall oblige the CAA to accept an application for the issue of a certificate of airworthiness or validation or for the variation or renewal of any such certificate when the application is not supported by such reports from such approved persons as the CAA may specify (either generally or in a particular case or class of cases).
10—(1) (a) An aircraft registered in the United Kingdom in respect of which a certificate of airworthiness is in force shall not fly unless the aircraft (including in particular its engines), together with its equipment and radio station, is maintained in accordance with a maintenance schedule approved by the CAA in relation to that aircraft.
(b)An aircraft registered in the United Kingdom in respect of which a certificate of airworthiness in either the transport or in the aerial work category is in force shall not fly unless there is in force a certificate (in this Order referred to as a ‘certificate of maintenance review’) issued in respect of the aircraft in accordance with the provisions of this article and such certificate shall certify the date on which the maintenance review was carried out and the date when the next review is due.
(2) A maintenance schedule approved pursuant to paragraph (1) in relation to an aircraft in respect of which there has been issued a certificate of airworthiness in either the transport or in the aerial work category shall specify the occasions on which a review must be carried out for the purpose of issuing a certificate of maintenance review.
(3) (a) Subject to sub-paragraph (b), a certificate of maintenance review may be issued for the purposes of this article only by:
(i)the holder of an aircraft maintenance engineer’s licence:
