(1) This section applies if:
(a) a transport security program given to an aviation industry participant under section 26B (the existing program ) is in force; and
(b) the Secretary is no longer satisfied that the existing program is appropriate:
(i) because there is a change in the circumstances that relate to aviation security; or
(ii) because there is a change in circumstances that could impact on aviation security; or
(iii) for some other reason.
(2) The Secretary may:
(a) give the participant another transport security program under section 26B (a revised program ); or
(b) by written notice to the participant, cancel the existing program.
