Maximum Take-Off Weight increase for aeroplanes managed by an approved self-administering aviation organisation (ASAO) - (DP 1912SS)

Closed 28 Sep 2019

Opened 30 Aug 2019

Results updated 4 Dec 2019

CASA conducted public consultation via a discussion paper DP 1912SS – 'Maximum take-off weight limit for aeroplanes managed by approved self-administering aviation organisations' – from 30 August to 28 September 2019.

This detailed the proposition to amend the relevant regulations to permit three-axis aeroplanes up to a maximum weight of 760 kg, regardless of whether the aircraft is equipped to land on water or not, to be administered by an ASAO.

Feedback was sought on whether the potential benefits to aviation safety and the aviation community, as outlined in the discussion paper, would likely be realised.

A total of 408 responses were received from individuals and persons representing a group, business or organisation. Most respondents indicated strong support for CASA to consider the policy proposition to increase the MTOW of aeroplanes that an ASAO may administer, with 83% of respondents supporting an MTOW increase up to 760 kg.

This Discussion Paper explores the policy proposition that an Approved Self Administering Aviation Organisation (ASAO) may administer aeroplanes with a MTOW greater than 600 kg up to a maximum of 760 kg, and that they conduct only recreational activities or flying training on the basis that the organisation demonstrates to CASA a capability of maintaining an acceptable level of aviation safety.

The premise for discussion is for a change to the MTOW limitations that currently apply to 3-axis aeroplanes. It would potentially amend the relevant regulations to permit 3-axis aeroplanes up to a maximum weight of 760 kg, regardless of whether the aircraft is equipped to land on water or not and to be included as aircraft that could be administered by an ASAO. Other limitations such as maximum stall speed would not be changed by this proposal.

The proposal is for the establishment of a new operating classification within an ASAO's safety system to manage operations of aircraft within the proposed higher MTOW and above the 600 kg limit which currently exists.

CASA previously considered a similar proposal in 2008 which did not result in changes. Given recent requests CASA wishes to get feedback from all parties on this topic using this discussion paper. We hope submissions will examine the proposed change and highlight any perceived pros, cons, effects of aviation safety as well as potential financial impacts. The provision of relevant data or practical examples would be very beneficial to our review.

Why your views matter

CASA seeks input and welcomes feedback and relevant comment from all stakeholders in relation to proposed changes to the regulations.  Importantly, this paper outlines a proposal that might result in a change to the regulations. This does not mean CASA has already decided to make such a change.

Document for review

  • Other alternatives.

Prior to deciding to make any change, CASA is committed to considering the feedback relevant to this Discussion Paper to ensure we maintain and enhance aviation safety.

The purpose of this Discussion Paper is to seek feedback from the aviation community with regards to the relevance of the stated benefits, the identified risks and the industry impacts more broadly.
