Part 172 of CASR explanation of changes

Rule change

We’re currently making changes to Part 172 of the Civil Aviation Safety Regulations (CASR). The information provided in this section outlines what is changing, what you need to know and do, and links to any relevant guidance and reference material. 

The last significant change to Part 172 occurred in 2011 when many of the regulations relating to approvals were repealed and replaced by regulations in Part 11 of CASR. 

The most recent change to the Part 172 Manual of Standards (MOS) occurred in late 2019 when the standards for parallel instrument approach operations were omitted in order to give effect to new equivalent standards introduced by the International Civil Aviation Organisation within the Procedures for Air Navigation Services – Air Traffic Management (PANS-ATM, Doc. 4444). 

What is changing

Since 2003, there have been 8 amendments to Part 172 MOS to incorporate new standards and procedures. However, there has not been a holistic review of the Part 172 and the MOS in the 15 years since introduction.

There is also a need to make the following specific changes to the Part 172 suite: 

  • incorporate current temporary arrangements for allowing low level helicopter operations within a control zone in close proximity to the primary airport 
  • adopt the controller fatigue risk management standards recently promulgated by the International Civil Aviation Organization (into this part of CAO 48.1 or its successors) 
  • adopt recent amendments to ICAO standards for the conduct of simultaneous operations to close-spaced parallel runways 
  • implement a contemporary regulatory structure requiring accountable, responsible, safety management system and quality management system managers consistent with other CASR Parts 
  • review the penalties in the regulation. 

These matters are being addressed in Project AS 14/23 - Post Implementation Review of CASR Part 172 - Air traffic service providers.

Indirectly, Part 172 is included in the scope of work for Project SS 14/07 - Review of guidance material for the development and implementation of Safety Management Systems.

Guidance material

There are no current guidance materials related to changes for Part 172 of CASR changes.
