Provided further that the Director General shall publish regulatory instruments containing objective criteria for the determination of whether an aircraft is to be covered by a national permit to fly or alternatively by a national certificate of airworthiness.
(2) The Director General shall issue a national permit to fly if he is satisfied that the aircraft is fit to fly, having regard to the airworthiness of the aircraft and the conditions to be attached to the permit. A national permit to fly may be issued subject to such conditions as the Director General deems appropriate.

(ii) modification or maintenance of the aircraft or any of its equipment necessary for the airworthiness of the aircraft, for the purpose of ensuring that the aircraft remains airworthy;
(b) the completion of an inspection, modification or maintenance of the aircraft is required as a condition of the permit to fly;
(c) any condition in the permit is not complied with; or
(d) the aircraft, its engines and propellers, or such of its equipment as is necessary for the airworthiness of the aircraft, are modified or repaired.
(4) A national permit to fly that ceased to be in force in accordance with sub-article (3) shall come back into force as soon as the inspection, modification, repair or remedy to the breach of any relevant condition has been approved by the Director General or by a person approved by the Director General for that purpose.
(5) A national permit to fly shall be valid for a time specified in writing by the Director General.
(6) An aircraft flying in accordance with a national permit to fly shall not fly:
(a) for the purpose of public transport, commercial air transport or commercial operation;
(b) at night or in accordance with IFR Rules; or
(c) for hire.
(7) In the case of an EASA Part-21 Permit to Fly issued by the Directorate, that permit shall be issued in accordance with the Basic Regulation and any implementing rules made under that Regulation which would apply as if the aircraft were an EASA aircraft.
