CASR Part 133 - Air transport and aerial work operations - rotorcraft

Under development

Part 133 of CASR will include the regulatory requirements that will apply in addition to, or substitute for, the general operating and flight rules prescribed in Part 91 when using rotorcraft for air transport operations.

Who Part 133 affects

Part 133 will affect operators of helicopters, gyroplanes or powered-lift aircraft who currently undertake charter passenger or cargo operations under subregulation 206 (1) (b) of the Civil Aviation Regulations 1988 (CAR) and who intend to undertake these operations under the CASR.

Key proposals

Part 133 is being developed under Standard Development project OS 99/45.The applicability and standards of Part 133 are aligned closely to Australia's obligations as a member State of the International Civil Aviation Organization (ICAO) and to CASA's hierarchy of priorities within the Classification of Civil Aviation Activities for rotorcraft. These support a systems-based approach to safety by making clear who is responsible for complying with each rule and ensuring that operators are responsible for providing guidance, training and monitoring for their personnel on how to comply with the regulations and the operator's policies when conducting operations under their Air Operator's Certificate.

Part 133 operators will require certification under Part 119 with its requirements for:

  • continuing airworthiness under an approved aircraft maintenance program
  • operational risk management under a safety management system
  • fatigue risk management systems for crew
  • procedural training and checking of flight crews under the operator's training and checking system, either in-house or provided by an arrangement with a Part 142 certified training and checking provider.

Part 133 will also:

  • enhance the standards for air transport operations conducted under the visual flight rules at night by linking the requirements for these operations more directly to the safety risks of such operations and the requirements for instrument flight rules operations
  • establish safety-based outcomes for overwater flights and the equipment requirements for such operations, and provide a greater focus for operators to establish procedures, training and recency requirements that are most appropriate to the circumstances, risks and complexity of their operations
  • establish rotorcraft performance standards based on ICAO requirements that incorporate consideration of exposure to the potential for a forced landing, and that allow for risk management of this exposure through appropriate consideration of the likelihood and consequences of a forced landing event.

Part 133 history

The Part 133 history includes project and consultation activities conducted in relation to Part 133.
