In December 2018, CASA issued Civil Aviation Safety Regulation (CASR) Part 119 (Australian air transport operators—certification and management) and CASR Part 133 (Australian air transport operations—rotorcraft).
CASR Part 119 outlined safety management system requirements for air transport operators (including operators of charter flights in single-engine helicopters). CASR Part 133 outlined flight crew training and checking requirements for air transport operators of helicopters.
More explicitly, CASR 133.415 (Assignment of flight crew to different multi-engine rotorcraft):
A rotorcraft operator’s exposition must include the following:
(a) a description of the circumstances in which the operator may assign a flight crew member to duty on 2 or more different multi-engine rotorcraft;
(b) the combinations of different rotorcraft that a single flight crew member may be assigned to duty on by the operator;
(c) the flying experience, checks and training that a flight crew member must gain or complete, while the flight crew member is employed by the operator, before being assigned to duty on 2 or more different multi-engine rotorcraft…
There were no similar requirements introduced for single-engine helicopters, other than in command under supervision (ICUS) requirements, which were effectively the same as those previously in place. However, the acceptable means of compliance (AMC) for the requirement to ensure flight crew were competent (CASR 133.375) stated:
The training and checking regulations require a minimum level of competence for flight crew operating under this Part. Part 61 of CASR and its MOS stipulate minimum competence standards for holders of pilot licences and ratings. An operator is required to ensure that the competence of their flight crew is at least at this level.
Regulation 133.375 provides that an operator must have assessed the crew member as being competent to perform the duties assigned to them. These regulations are not meant to be a one-size-fits-all set of regulations and it is imperative that operators formulate their own specific set of equal or better standards after thorough assessment of their operational characteristics. Appropriate use of training needs analysis with input from the SMS will be crucial in this development. Operations identified by the SMS as having a higher degree of difficulty may require higher training or checking standards than set out in these regulations.
