(1) This section applies if, after the end of the period specified in a show cause notice given under section 30DH:
(a) CASA is satisfied that a serious and imminent risk to air safety would exist if the civil aviation authorisation were not varied, suspended or cancelled; and
(b) the grounds for CASA's belief are related to the circumstances that gave rise to CASA's decision to suspend the authorisation under section 30DC.
(2) CASA may vary, suspend or cancel the authorisation, by written notice given to the holder of the authorisation within 5 business days after the end of the period specified in the show cause notice.
Note: The suspension under section 30DC continues in force beyond the end of the period specified in the show cause notice and may continue until the end of the 5 days that CASA has to decide whether to vary, suspend or cancel the authorisation--see section 30DJ.
