Artikel 7

A. Certificates of airworthiness, certificates of competency and licenses issued or rendered valid by one Contracting Party and still in force, shall be recognized as valid by the other Contracting Party for the purpose of operating the air services on the specified routes provided that such certificates or licenses were issued or rendered valid pursuant to and in conformity with the standards established under the Convention. Each Contracting Party reserves the right, however, to refuse to recognize, for the purpose of flights above its own territory, certificates of competency and licenses granted to any of its nationals by the other Contracting Party.
B. If the privileges or conditions of the license or certificates referred to in paragraph A above, issued by the Aeronautical Authorities of one Contracting Party to any person or aircraft, should permit a difference from the standards established under the Convention, and which difference has been filed with the International Civil Aviation Organization, the Aeronautical Authorities of the other Contracting Party may request consultations with the Aeronautical Authorities of that Contracting Party with a view to satisfying themselves that the practice in question is acceptable to them. Failure to reach a satisfactory agreement in these matters regarding flight safety will constitute grounds for the application of Article 4 of this Agreement.
