Part 133 of the Civil Aviation Safety Regulations (CASR) covers the rules for air transport in rotorcraft.
The term ‘air transport’ replaces both charter, regular public transport (RPT) and air ambulance when conducted for hire or reward. It adds the transport of medical supplies or medical personnel for hire or reward as well.
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.
