Australia’s Civil Aviation Safety Authority (CASA) has released compliance timelines for certain Part 133 public, ambulance, and rotorcraft operators to transition their training and checking systems to recently adopted new flight operations regulations. Helicopter operators must ensure that CASA has a current copy of their proposed training and checking systems manual no later than March 31, 2025. A key change to the transition approach is a self-assessment by operators. It’s aimed at ensuring the accountable person is confident that the training and checking requirements have been properly addressed in operational procedures. Rotorcraft operators have until July 1, 2025, to implement their systems.
