If the duties and functions normally attached to the State of Registry are transferred pursuant to Article 83
bis, the State of the Operator will be internationally responsible and liable for them and will implement them in accordance with its own laws and regulations.
Flight time, flight duty periods, duty periods and rest periods for fatigue management are covered under Annex 6 Part I:
For the purpose of managing fatigue, the State of the Operator shall establish regulations specifying the limitations applicable to the flight time, flight duty periods, duty periods and rest periods for flight crew members.
But if the crews of VH-registered aircraft are operating on CASA licences, my interpretation is that the existing (State of Registry-approved) FDTLs will apply, irrespective of any 83
bis agreement.
However, as previously stated, others may disagree.
