6.2. In the event of disagreement between the parties over the effectiveness of the measures taken, the notifying party may require the other party to take immediate steps to prevent the organization from carrying out maintenance tasks for civil aviation products under its control. If the other party does not take these measures within fifteen working days of the request of the notifying party, the powers conferred on the competent authority of the other party in accordance with this procedure are suspended until the matter is satisfactorily resolved by the joint committee in accordance with the provisions of the agreement. Pending the adoption by the Joint Committee of a decision on this matter, the notifying party may take all the measures it deems necessary to prevent the organization from carrying out, under its control, tasks of maintenance of civil aviation products. IN THE AIM to improve cooperation and improve civil aviation safety efficiency, bilateral agreements and arrangements allow the sharing of the airworthiness certificate for civil aviation products between two countries. Bilateral agreements facilitate mutual airworthiness certification of civilian aviation products imported and exported between two signatory states. A bilateral airworthiness agreement (BAA) or a bilateral aviation security agreement (BASA) establishing airworthiness implementation procedures (IAP) provide for technical aviation cooperation between the FAA and its civil aviation authorities. Through these activities, BASA reduces the economic burden on airlines and aircraft operators. In addition to the new annexes, the EU and the US have agreed to amend the DEA Maintenance Annex to allow maintenance organisations from all EU member states to participate in BASA`s safety cooperation and to confirm the highest aviation safety standards in the EU and the supervisory function of the European Union Aviation Safety Agency (EASA).
4.3. Contracting parties may seek assistance from the civil aviation authority of a third country in carrying out its prudential supervisory and supervisory functions if a party`s authorisation has been granted or renewed by an agreement or formal agreement with that third country.
