(2) If such corrective action is not taken within such reasonable period as a surveyor may specify, the surveyor, or Certifying Authority, shall notify the Secretary of State who may suspend the validity of the particular certificate issued to the ship.
(3) The Secretary of State shall give notice of any such suspension to the owner, to the surveyor, and to the Certifying Authority who in turn shall notify the master.
