ARTICLE III (a) The charges which either Contracting Party may impose or permit to be imposed on the designated air carrier or carriers of the other Contracting Party for the use of airports and other facilities shall not be higher than would be paid for the use of such airports and facilities by its national aircraft employed in similar international air services. (b) Fuel, lubricating oils and spare parts introduced into, or taken on board aircraft in, the territory of one Contracting Party by, or on behalf of, any designated air carrier of the other Contracting Party and intended solely for use by the aircraft of such carrier shall be accorded, with respect to customs duties, inspection fees and other charges imposed by the former Contracting Party, treatment not less favorable than that granted to national air carriers engaged in inter- national air services or such carriers of the most favored nation. (c) Supplies of fuel, lubricating oils, spare parts, regular equipment and aircraft stores retained on board aircraft of any designated air carrier of one Contracting Party shall be exempt in the territory of the other Contracting Party from customs duties, inspection fees or similar duties or charges, even though such supplies be used by such aircraft on flights within that territory. ARTICLE IV Certificates of airworthiness, certificates of competency and licenses issued or rendered valid by one Contracting Party and still in force shall be recognised as valid by the other Contracting Party for the purpose of operation of the agreed services.

(b) The laws and regulations of each Contracting Party as to the admission to, sojourn in and departure from its territory of passengers, crew and cargo of aircraft, such as regulations relating to entry, clearance, immigration, passports, customs and quarantine, shall be observed.
