After reading this in CASRs, I resolved not to bother to try to work out what rules apply to parachute operations. Life is way too short.
202.502 Transitional—parachute descents authorised by CASA
(1) Despite regulation 202.501, Part 105 does not apply in relation to a parachute descent if the descent is authorised by, and conducted in accordance with:
(a) instrument CASA 263/02 or instrument CASA 36/19 (as either is in force from time to time); and
(b) if the descent is being undertaken by a trainee parachutist or tandem parachutist—instrument CASA 11/17 or instrument CASA 84/18 (as either is in force from time to time); and
(c) subsection 15 of Civil Aviation Order 20.16.3 (as in force immediately before 2 December 2021).
(2) If Part 105 does not apply to a parachute descent because of the operation of subregulation (1), Part 105 also does not apply to any other parachuting activity undertaken for the purposes of the descent.
(3) Despite the repeal of regulation 152 of CAR by Schedule 2 to the amending regulations, instruments CASA 263/02 and CASA 36/19 (as in force immediately before the commencement of Schedule 2 to the amending regulations) continue in force (and may be dealt with) after that commencement as if that repeal had not happened.
(4) This regulation is repealed at the end of 1 December 2023.
