Article 12 Revocation, suspension and variation of noise certificate or exemption
Where the Governor has reasonable grounds to believe that an aircraft is not complying with the applicable noise standards or any conditions under which the noise certificate or exemption was issued, the Governor may, by serving written notice on the owner or operator of the aircraft, provisionally suspend any noise certificate issued under article 6(1) or any exemption issued under article 11(1), pending inquiry into or consideration of the case.
Where the Governor is satisfied that there are sufficient grounds to do so after due inquiry into or consideration of the case, the Governor may, by serving written notice on the owner or operator of the aircraft—
suspend or revoke any such noise certificate or exemption, or
vary the conditions subject to which any such noise certificate or exemption was issued.
Where the noise certificate or exemption is provisionally suspended, suspended or revoked, that suspension or revocation takes effect when the Governor serves written notice on the owner or operator of the aircraft.
Where a noise certificate or exemption is provisionally suspended under paragraph (1), suspended, revoked, or varied under (2), the holder of the certificate or exemption, or any person having possession or custody of the certificate or exemption, must surrender it to the Governor within a reasonable time after being required to do so.
The written notice in paragraphs (1) and (2) must state—
the date of the notice;
the grounds for suspension or revocation of the certificate or exemption;
the duration of the suspension;
the conditions under which the suspension may be lifted.
The Governor may at any time lift the suspension of a noise certificate or exemption that has been suspended provisionally or otherwise.
