Artikel 6

1. Certificates of airworthiness, certificates of competency and licenses issued or rendered valid by one Party and still in force shall be recognized as valid by the other Party for the purpose of operating the agreed services provided that the requirements under which such certificates and licenses were issued or rendered valid are equal to or above the minimum standards which may be established pursuant to the Convention.
2. If the privileges or conditions of the licenses or certificates referred to in paragraph 1 above, issued by the aeronautical authorities of one Party to any person or designated airline or in respect of an aircraft used in the operation of the agreed services, should permit a difference from the minimum standards established under the Convention, and which difference has been filed with the International Civil Aviation Organization (ICAO), the other Party may request consultations between the aeronautical authorities with a view to clarifying the practice in question.
3. Each Party reserves the right, however, to refuse to recognize for the purpose of flights above or landing within its own territory, certificates of competency and licenses granted to its own nationals by the other Party.
