(b) for which that responsibility is transferred to the designer under section 21.

(2) The designer ceases to be responsible for the maintenance of the procedure:

(a) if the designer has notified CASA and, if the procedure is published in the AIP, the AIS, under regulation 173.210 (as applied by section 18) that the designer has ceased to have that responsibility:

(i) on the day when the notice is given; or

(ii) if a later day is specified in the notice—on the later day; or

(b) if the designer has notified CASA and, if the procedure is published in the AIP, the AIS, under regulation 173.200 (as applied by section 18) that the designer has ceased to design the type of terminal instrument flight procedure concerned:

(i) on the day when the notice is given; or

(ii) if a later day is specified in the notice—on the later day; or
