ARTICLE 10

1. Consistent with the provisions of this Article, charges for the use of air navigation facilities, communication facilities and services, as well as, any charges for the use of each airport, including its installations, technical and other facilities and services ("user charges"), shall be made in accordance with the rates and tariffs established by each Party.

2. User charges which may be imposed by the competent charging authorities or bodies of each Party on the airlines of the other Party shall be just, reasonable, non-discriminatory and equitably apportioned among categories of users. In any event, user charges shall be assessed on all airlines of each Party on terms not less favorable than the most favorable terms available to any other airline at the time the charges are assessed.

3. User charges imposed on the airlines of the other Party may reflect, but shall not exceed, an equitable portion of the full cost, to the competent charging authorities or bodies, of providing the appropriate airport, air navigation, and aviation security facilities and services, and in the case of airport charges, may provide for a reasonable rate of return, after depreciation. Facilities and services for which charges are made shall be provided on an efficient and economic basis. Reasonable notice shall be given prior to changes in user charges.

4. Each Party shall encourage consultations between the competent charging authorities or bodies in its territory and airlines using the services and facilities, and shall encourage the competent charging authorities or bodies and the airlines to exchange such information as may be necessary for an accurate review of the reasonableness of the charges in light of the principles of paragraphs (2) and (3) of this Article.
