Article 83 bis is an amendment to the Chicago Convention that became
effective in June 1997. It authorizes Contracting States to make bilateral
transfers of safety oversight responsibilities related to the lease, charters,
and interchange of aircraft. It gives states a basis and legal framework for
entering into bilateral agreements transferring responsibilities under Articles
12 (Rules of the air), 30 (Aircraft Radio Equipment), 31 (Certificates of
Airworthiness), and 32 (a) (licenses of Personnel).
Typically, the State of Registry transfers the responsibilities to the state
in which the aircraft are to be based (State of Operator).
Article 83 bis allows placement of safety oversight responsibilities with the
State that is in a better situation to discharge safety oversight.
Article 83 bis guarantees that bilateral agreements for transfers of
oversight responsibilities are recognized by all ICAO States.
Bermuda currently has agreements with:
* Russian, MoT
* Austrian, Austro Control
* Republic of Uzbekistan, Flight Safety Oversight
* Republic of Azerbaijan, State Concern
