Sec. 221.142  Method of withdrawing portion of authority conferred by 

concurrence.

    If a carrier desires to issue a concurrence conferring less 
authority than a previous concurrence given to the same carrier, the new 
concurrence shall not direct the cancellation of such previous 
concurrence. In such circumstances, such previous concurrence shall be 
revoked by issuing and filing a Notice of Revocation of Concurrence in a 
form acceptable to the Office of International Aviation. Such revocation 
notice shall include reference to the new concurrence.
