On 8 April 2013, the Civil Aviation Safety Authority (CASA) announced amendments to the Civil Aviation Order Part 48 to introduce new arrangements for management of flight crew fatigue based on the following 3 tier system:
- Businesses with simple operations will not be required to meet new fatigue management obligations (Tier 1).
- Operations that pose a moderate fatigue risk will be able to continue those operations by meeting certain obligations with minimal cost impact (Tier 2).
- Complex operations that pose a significant fatigue risk will be required to either develop a Fatigue Risk Management System (FRMS), or significantly change their operations in order to comply with the prescriptive limits to avoid the need for an FRMS (Tier 3).
The new arrangements are consistent with International Civil Aviation Organization standards and address deficiencies in the current regulations to take account of advancements in the science of fatigue and evidence of accidents and near misses, both within Australia and internationally. A Regulation Impact Statement was prepared by CASA and has been assessed as adequate by the Office of Best Practice Regulation.
