Part 121 of the Civil Aviation Safety Regulations (CASR) covers the air transport rules for larger aeroplanes.
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 will also need to comply with PART 119 This rule sets out the general certification and management for air transport operations.
If you conduct other air transport operations, such as smaller aeroplane air transport or rotorcraft air transport, you need to comply with other CASR flight operations rules.
