Explanatory Statement

Civil Aviation Safety Regulations 1998

Exemption  take-off with traces of frost

 

Legislation

Section 98 of the Civil Aviation Act 1988 (the Act) empowers the Governor-General to make regulations for the Act and the safety of air navigation.

Under paragraph 244 (1) (c) of the Civil Aviation Regulations 1988 (CAR 1988), immediately before taking off, the pilot in command of an aircraft must ensure that all external surfaces of the aircraft are completely free from frost and ice.

 

Subregulation 11.160 (1) of the Civil Aviation Safety Regulations 1998 (CASR 1998) provides that, for subsection 98 (5A) of the Act, CASA may grant an exemption from a provision of the regulations, including CAR 1988, in relation to a matter mentioned in that subsection. Under subregulation 11.160 (2), an exemption may be granted to a person, or to a class of persons, and may specify the class by reference to membership of a specified body or any other characteristic.

 

Under subregulation 11.205 (1) of CASR 1998, CASA may impose conditions on an exemption if this is necessary in the interests of the safety of air navigation. Under regulation 11.225 of CASR 1998, an exemption must be published on the Internet. Under subregulation 11.230 (1), the maximum duration of an exemption is 3 years.

 

Instrument

CASA previously issued instrument CASA EX13/14, which allowed larger aircraft with maximum take-off weight (MTOW) over 5 700 kg conducting regular public transport (RPT) and charter operations to take off with residual traces of frost or ice.

 

This instrument renews the exemption in CASA EX13/14. The instrument exempts pilots in command of larger aircraft from complying with paragraph 244 (1) (c) of CAR 1988. The exemption is subject to a range of conditions, including that the aircraft must not have any frost, ice or snow adhering to the aircraft’s critical surfaces, other than a limited amount of frost, caused by cold-soaked fuel, on the underside of the wings in limited circumstances.

 

Having taken into account all relevant safety considerations, CASA is satisfied that larger aircraft engaged in RPT and charter operations may safely conduct take-off with frost adhering to the underside of their wings caused by cold-soaked fuel, provided that take-off is conducted in accordance with the aircraft flight manual, the flight crew operating manual or the dispatch deviation guide instructions. This means that the depth of frost permissible on the underside of the aircraft’s wings before commencing take-off will be determined by the aircraft manufacturer. The instrument also allows larger aircraft to conduct take-off with a thin layer of hoarfrost on the upper fuselage if permitted by the aircraft manufacturer.

 

Legislation Act 2013 (LA)

For subsection 98 (5A) of the Act, CASA may, by instrument, grant an exemption from compliance with a provision of the Regulations. An instrument issued under paragraph 98 (5A) (a) of the Act is a legislative instrument if the instrument is expressed to apply to a class of persons or aircraft. The exemption applies to a class of persons, being pilots in command of aircraft with an MTOW of more than 5 700 kg that are engaged in RPT or charter operations. The exemption is, therefore, a legislative instrument subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LA.

 

Consultation

In 2011, CASA published a draft of proposed amendments to Part 91 of CASR 1998,

which included proposed standards relating to frost, ice and snow adhering to an aircraft, and invited comments from the aviation industry and the general public on the draft amendments.

 

In 2015, CASA published a further draft of proposed amendments to Part 91 of CASR 1998 and a draft of proposed provisions of Part 121 of CASR 1998, which would apply to RPT and charter operations in large aeroplanes. The proposed standards included provisions relating to frost, ice and snow adhering to an aircraft. CASA again invited comments from the aviation industry and the general public on the draft provisions.

 

This instrument takes into account any comments received in response to that consultation.

 

Further consultation under section 17 of the LA has not been undertaken specifically for this instrument. The instrument remakes instrument CASA EX13/14, which had similar scope and effects and which expires at the end of June 2016.

 

CASA is satisfied that no further consultation is appropriate or necessary in these circumstances.

 

Statement of Compatibility with Human Rights

A Statement of Compatibility with Human Rights is at Attachment 1.

 

Office of Best Practice Regulation (OBPR)

A Regulation Impact Statement (RIS) is not required because the exemption is covered by a standing agreement between CASA and OBPR under which a RIS is not required for exemptions (OBPR id: 14507).

 

Making and commencement

The exemption has been made by a delegate of CASA relying on the power of delegation under subregulation 11.260 (1) of CASR 1998.

 

The instrument commences on 1 July 2016 and is repealed at the end of 31 May 2019.

[Instrument number CASA EX101/16]

Attachment 1

Statement of Compatibility with Human Rights

Prepared in accordance with Part 3 of the
Human Rights (Parliamentary Scrutiny) Act 2011

 

Exemption — take-off with traces of frost

 

This legislative instrument is compatible with the human rights and freedoms recognised or declared in the international instruments listed in section 3 of the Human Rights (Parliamentary Scrutiny) Act 2011.

 

Overview of the legislative instrument

The legislative instrument permits a larger aircraft with a maximum take-off weight of more than 5 700 kg that is engaged in regular public transport operations or charter operations to take off with frost adhering to the underside of its wings if that frost has been caused by cold-soaked fuel. The exemption is subject to conditions directed by CASA in the interest of safety, including that take-off be conducted in accordance with the aircraft flight manual, the flight crew operating manual or the dispatch deviation guide instructions for the aircraft, which specify the depth of frost permissible on the underside of the aircraft’s wings in order to conduct a safe take-off. The exemption also permits the aircraft to take off if there is a thin layer of hoarfrost on the upper fuselage of the aircraft if permitted by the aircraft manufacturer.

 

The primary purpose of the legislative instrument is to allow larger aircraft to take off even though they are not completely free from frost and ice, subject to compliance with the stated conditions.

 

Human rights implications

This legislative instrument does not engage any of the applicable rights or freedoms.

 

Conclusion

This legislative instrument is compatible with human rights as it does not raise any human rights issues.
