Each con- tracting party reserves the right to withdraw at any time the desig- nation of an airline and substitute the designation of another. The contracting party granting the rights shall, subject to Article 7 hereof, be bound to give, with a minimum of procedural delay, the appro- priate operating permission to the airline or airlines concerned; pro- vided that the airline or airlines so designated may be required to qualify before the competent aeronautical authorities of the contract- ing party granting the rights under the laws and regulations normally applied by those authorities before being permitted to engage in the operations contemplated by this Agreement; and provided that in areas of hostilities or of military occupation, or in areas affected thereby, such operation shall be subject to the approval of the com- petent military authorities. ARTICLE 4 In order to prevent discriminatory practices and to assure equality of treatment, both contracting parties agree that: (a) Each of the contracting parties may impose or permit to be imposed just and reasonable charges for the use of public airports and other facilities under its control.

(b) Fuel, lubricating oils and spare parts introduced into the ter- ritory of one contracting party by the other contracting party or its nationals, and intended solely for use by aircraft of the airlines of such contracting party shall, with respect to the imposition of cus- toms duties, inspection fees or other national duties or charges by the contracting party whose territory is entered, be accorded the same treatment as that applying to national airlines engaged in interna- tional services and to airlines of the most-favored-nation. (c) The fuel, lubricating oils, spare parts, regular equipment and aircraft stores retained on board civil aircraft of the airlines of one contracting party authorized to operate the services described in the Annex shall, upon arriving in or leaving the territory of the other contracting party, be exempt from customs, inspection fees or similar duties or charges, even though such supplies be used or consumed by such aircraft on flights in that territory. (d) Each of the contracting parties agrees not to give a preference to its own airlines against the airlines of the other state in the appli- cation of its customs, immigration, quarantine and similar regula- tions or in the use of airports, airways or other facilities.
