Part 133 of CASR Australian air transport operations rotorcraft

Rule status


New rules for operators conducting air transport operations in rotorcraft commenced on 2 December 2021.

Part 133 of the Civil Aviation Safety Regulations (CASR) covers the rules for air transport in rotorcraft. These rules are specifically designed for rotorcraft and eliminate the time and cost that was involved in applying for exemptions under previous regulations.

The term air transport replaces both charter and regular public transport (RPT) and adds medical transport operations such as patient transport.

You should also read Part 119 which deals with the general certification and management for air transport operations.

If you conduct other operations, such as aerial work, you need to comply with other CASR flight operations Parts.
