We Asked, You Said, We Did

Below are some of the issues we have recently consulted on and their outcomes.

We Asked

CASA published a consultation draft of the proposed regulatory instrument for performance-based communication and surveillance on the CASA Consultation Hub from 18 April to 2 May 2018.

You Said

CASA received a total of three responses to the proposed instrument.

One of the main objectives of the consultation was to obtain feedback on whether open-ended relief statements for aircraft documentation, agreement with the communication service provider and the Minimum Equipment List (MEL) would be acceptable to foreign authorities in the long term. One response indicated that such open-ended statements didn't appear to be a problem. Another response queried if CASA would be prepared to accept the open-ended statements and how certain older aircraft equipment would be treated if it is determined or declared to be non-compliant by the State of design.

There was a suggestion to prepare and publish guidance on the subject in the form of an Advisory Circular (AC).

Other comments indicated preference for the use of less-restrictive statements concerning monitored performance of aircraft data link operations and training of the personnel.

Finally, a suggestion was provided to use the definitions contained in ICAO documents.

We Did

As PBCS is a recently developed concept and that it may take some time for operators to obtain the required documentation, CASA and foreign authorities should accept operator's request(s) to appropriate authorities or entities for documentation as an acceptable means of compliance. Otherwise, affected operators would be disadvantaged due to no fault of their own.

The comment regarding the possibility of certain aircraft equipment being declared non-compliant by State of design has been addressed so that the subject aircraft are no longer authorised to declare applicable RCP and RSP capabilities.

A new Advisory Circular on PBCS has been published by CASA to provide general guidance on the subject.

Suggestions to use less-restrictive statements on the monitoring of aircraft data link operations and training of the personnel have also been taken into consideration. The word "notification" has been replaced by "advice" in the context of data link monitoring. Furthermore, requirements for flight crew and other personnel have become more general so that having appropriate knowledge is considered acceptable. 

The definitions will remain the same. They are slightly reworded from those contained in ICAO documents and are for the purpose of the subject instrument only.

The regulatory instrument CASA 33/18 – Required Communication Performance and Required Surveillance Performance (RCP 240 and RSP 180) Capability Declarations – Direction 2018 – is available on the Federal Register of Legislation.

We Asked

CASA published the Draft CAAP 20.4-01 v 1.0 — Supplemental oxygen requirements for cabin crew members in pressurised aircraft operating at flight level 250 and below — on the CASA website from 22 February 2018 to 9 March 2018. We asked should the cabin crew supplemental oxygen requirements, as set out in Civil Aviation Order 20.4, apply in emergency situations where cabin crew may not be able to promptly access a supply of supplemental oxygen apply in certain circumstances.

You Said


CASA received a total of three submissions. All the respondents consented to having their comments published on the CASA website.

Key feedback

All responses received support the consultation explanation that CAO 20.4 need not be narrowly and strictly applied to supplementary oxygen requirements for pressurised aircraft engaged in flights not above flight level 250 when a sudden emergency results in extraordinary circumstances that mean cabin crew may not immediately be able to access a supply of supplementary oxygen.

We Did

Future direction

CASA will issue the final CAAP 20.4-01 v 1.0 verifying that cabin crew can use their professional judgment to deal with any number of threats to the aircraft, passengers and themselves during an emergency. Departure from narrow regulatory compliance may be excusable in situations where the evidence shows that the departure was necessary due to a sudden or extraordinary emergency.

We Asked

We asked for feedback on a proposal to implement MULTICOM 126.7 up to 5,000 feet AMSL in low level airspace at uncharted aerodromes, and to expand the radius of common traffic advisory frequency (CTAF) areas to 20 nautical miles.

The aim of the proposal was to implement MULTICOM 126.7 and enhance safety benefits for VFR and IFR aircraft, protect passenger transport operations and keep air traffic control transmissions separate from general transmissions at aerodromes.

You Said

We received 1,064 survey responses to this consultation and some written submissions.

Overall, 42.8% of survey respondents supported the proposal and 57.2% of respondents did not support the proposal. Respondents raised a number of important issues and concerns requiring further consideration.

The common issues, questions or suggestions were around:  

  • the extent of overlapping CTAFs
  • frequency congestion, either on MULTICOM 126.7 or within expanded CTAF areas
  • irrelevant transmissions from neighbouring aerodromes in expanded CTAF areas
  • procedures for inbound calls
  • radio carriage and workload implications for hang gliders and paragliders.

We Did

Due to the issues raised during consultation, CASA will not implement this proposal.

In acknowledgement of the broad support for the MULTICOM 126.7 component of this proposal, CASA is developing a new option that will be released for consultation later this month.  

We Asked

CASA published DP1618OS—Maintenance of limited category aircraft. Proposed Subpart 132.M of CASR—on the CASA website from 1-19 September 2017. The objectives of the DP were to provide owners, operators and maintainers of limited category aircraft with the opportunity to provide feedback on potential ways of regulating maintenance of limited category aircraft. Three options were proposed:

  • Continuing to have maintenance of limited category aircraft governed by the current rules.
  • Moving the maintenance requirements for limited category aircraft to Part 42 of CASR.
  • Having a dedicated Subpart 132.M of CASR dealing with maintenance of limited category aircraft.

CASA also consulted with stakeholders on 28 February 2017 at a public meeting held at the Stamford Plaza Hotel in Sydney.

You Said

22 online responses were received from industry participants in relation to the three proposed options. Of the 22 respondents, 17 provided their permission to publish their responses. The responses against the three options were as follows.


Option 1 - retain the present regulatory structure

No response                                        4

Unacceptable                                      10

Acceptable with change                      6

Acceptable without change                 2


Option 2 - incorporate the limited category aircraft maintenance rules into Part 42 of CASR

No response                                        4

Unacceptable                                      9

Acceptable with change                      8

Acceptable without change                 1


Option 3 - create a standalone maintenance Subpart 132.M of CASR

No response                                        0

Unacceptable                                      4

Acceptable with change                      10

Acceptable without change                 8


Outcome of consultation meeting held at Stamford Plaza Hotel 28th February 2017

18 industry participants provided unanimous support to proceed with development of a Subpart 132.M of CASR. Of these 18 participants, 9 stated by way of caveat that they would need to see the full policy detail before giving unqualified support to the proposal.

The support provided by industry participants at this meeting reflects the responses CASA received online.


Key feedback and policy changes

Predominantly, the feedback indicated that the development of a Subpart 132.M of CASR was the preferred option but respondents wanted to see further detail.

We Did

A detailed policy paper will be prepared and published on CASA's Consultation Hub.

Responses to the policy draft will be analysed and regulations will be drafted to give effect to the agreed policies.

We Asked

In August 2017, we surveyed readers of Flight Safety Australia (FSA) magazine about their preferences for delivery and frequency of FSA, which since 2012, has been delivered electronically, via an app for tablets, and the flightsafetyaustralia.com website. We wanted to assess reader’s preferences before making any changes to the magazine’s content and how it’s delivered.

You Said

Our readers said they felt the balance was about right in the coverage of aviation safety issues but would like to see more close calls and accident reports. They also said they wanted aviation safety information more often from the current bi-monthly app and news stories most days.

We Did

From January we are going to increase the frequency of articles including close calls and accident reports, with new stories every week and a monthly edition to download as well as topical news stories published daily on the news site.

We Asked

Since the commencement of Part 66 in June 2011, CASA has received valuable feedback from stakeholders—including Part 66 licence holders and training organisations—on the implications and effects of the legislation. Feedback has highlighted the opportunity to simplify and clarify some aspects of the legislation, and address anomalies, gaps and unintended consequences via conduct of a post implementation review (PIR) of Part 66 of the Civil Aviation Safety Regulations 1998 (CASR).

In support of the PIR, CASA invited submissions to the Post implementation review of Part 66 - Continuing airworthiness - aircraft engineer licences and ratings (PIR 1703MS) from 21 February 2017 to 26 May 2017.

The objective of this consultation was to provide an opportunity for the aircraft maintenance sector to comment on matters relating to aircraft maintenance engineer licences and ratings, covered by Part 66 of CASR, the Part 66 Manual of Standards (MOS) and associated advisory material. CASA asked industry to identify issues that they wanted the review team to address and ideas for possible solutions.

You Said


CASA received a total of 70 submissions; 48 respondents consented to having their comments published on the CASA website.

Key feedback

Comments made in the submissions demonstrated that the majority of issues could be grouped into three main 'issues':

  1. Part 66 of CASR, the Part 66 MOS and associated advisory material:
    1. complexity of Part 66 regulations
    2. complexity of the Part 66 MOS
    3. the Part 66-related ACs and Part 66 AMC/GM document are not easily understood
    4. lack of true harmonisation with EASA (as originally intended)
    5. lack of clarity and understanding of the Part 66 regulations and Part 66 MOS
    6. continued use of two sets of regulations (Civil Aviation Regulations 1988 (CAR) and CASR)
  2. licence privileges:
    1. lack of understanding of privileges/limitations
    2. complexity of exclusions on licences
    3. maintaining licence currency (6 months in 24 month requirement)
    4. B1 licence privilege:
      1. understanding what is a 'simple test'
      2. understanding avionic line replaceable unit (LRU) privileges
  3. aeroskills training (that leads to grant of a Part 66 licence):
    1. structure of the training, including knowledge requirements (EASA modules/units of competency)
    2. training pathways
    3. cost of training
    4. type training too complex/difficult
    5. access to training by individuals in remote parts of the country
    6. RPL problems.

We Did

Future direction

CASA expects to establish a CASA/industry Part 66 PIR Working Group soon. The role of the working group will be to contribute relevant technical expertise and industry sector insight to:

  • the analysis and review of the identified issues
  • the development of proposed solutions
  • the formulation of recommendations for improvements to the Part 66 legislation and associated guidance material.
