(1)Whereas a Convention for the unification of certain rules relating to damage caused by aircraft to third parties on the surface was, on the twenty-ninth day of May, nineteen hundred and thirty-three, signed in Rome on behalf of His Majesty, and a copy of that Convention has been laid before each House of Parliament:
And whereas it is expedient that provision should be made for giving effect to the said Convention:
Now, therefore, His Majesty may, if it appears to His Majesty in Council to be necessary or expedient so to do for the purpose of giving effect to the said Convention, make an Order in Council—
(a)directing—
(i)that the provisions set out in the Order shall, in relation to aircraft registered in any such country other than the United Kingdom as may be specified in the Order, have effect in lieu of the provisions of this Part of this Act, save section forty-one; or
(ii)that all or any of the said provisions shall, in relation to such aircraft as aforesaid, have effect subject to such modifications, adaptations and exceptions as may be specified in the Order ;
(b)making such provision as appears to His Majesty in Council to be required for securing that an aircraft registered in the United Kingdom shall not leave the United Kingdom on a flight to or over any such country as aforesaid, unless there is on board the aircraft a certificate relating to a policy of insurance, a security or a deposit of money in respect of the aircraft, being a certificate in such form, and issued by such person, and containing such particulars, as may be prescribed by the Order.
(2)If the Convention recited in the foregoing subsection is amended by any Convention or agreement to which His Majesty or His Majesty's Government in the United Kingdom is a party, the said subsection shall have effect as if any reference therein to " the said Convention " were a reference to the first-mentioned Convention as so amended.
