party granting the rights shall, subject to Article 6 hereof, be bound
to give the appropriate operating permission to the airline or airlines
concerned; provided that the airline so designated may be required
to qualify before the competent aeronautical authorities of the con-
tracting party granting the rights under the laws and regulations
normally applied by these 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 inauguration shall be subject to the approval of the
competent military authorities.
(b) It is understood that either contracting party granted com-
mercial rights under this agreement should exercise them at the
earliest practicable date except in the case of temporary inability to
do so.
ARTICLE 3
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. Each of the contracting parties
agrees, however, that these charges shall not be higher than would
be paid for the use of such airports and facilities by its national
aircraft engaged in similar international services.
(b) Fuel, lubricating oils and spare parts introduced into the
territory of one contracting party by the other contracting party or
its nationals, and intended solely for use by aircraft of such other
contracting party shall be accorded national and most-favored-nation
treatment with respect to the imposition of customs duties, inspection
fees or other national duties or charges by the contracting party whose
territory is entered.
(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 routes and services de-
scribed 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.
