Explanatory Statement

Civil Aviation Safety Regulations 1998

Exemption — aircraft operating without carriage of Mode S transponder equipment (Goldrush Ballooning)

 

Legislation

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

 

Subregulation 207 (2) of the Civil Aviation Regulations 1988 (CAR 1988) provides that a person must not use an Australian aircraft in a class of operation if it is not fitted with such instruments, or is not fitted with or carrying such equipment, as CASA has approved and directed. Under subregulation 5 (1) of CAR 1988, where CASA may issue directions under CAR 1988, it may do so in the form of a Civil Aviation Order (CAO).

 

CAO 20.18 sets out directions issued by CASA under regulation 207 of CAR 1988 in relation to the instruments and equipment to be carried on board aircraft. Paragraph 9E.2 of CAO 20.18 provides, among other things, that an aircraft first registered on or after 6 February 2014 that is operated in Class A, B, C or E airspace, or above 10 000 feet above mean sea level in Class G airspace, must carry a serviceable Mode S transponder that meets specified standards. Paragraph 9E.2 also applies to an aircraft that is modified by having its transponder installation replaced on or after 6 February 2014.

 

Under subregulation 11.160 (1) of the Civil Aviation Safety Regulations 1998 (CASR 1998), for subsection 98 (5A) of the Act, CASA may grant an exemption from a provision of a CAO in relation to matters affecting the safe navigation and operation of aircraft.

 

Under regulation 11.225 of CASR 1998, an exemption must be published on the Internet. Under subregulation 11.230 (1), an exemption ceases on the day specified within it (but no longer than 3 years after its commencement) or, if no day is specified, 3 years after commencement.

 

Background

Goldrush Ballooning Pty Ltd (the operator) is a Melbourne-based hot air balloon company that operates a fleet of hot air balloons. The fleet of balloons share a small number of transponders. The transponders are fitted to the basket of the balloon, but it is the balloon envelope – not the basket – that bears the aircraft registration marking. It is common for baskets (with variable size and passenger capacity) to be swapped between balloon envelopes to match the needs of each operation and, therefore, there is no specific association between a balloon envelope and a basket. Transponders fitted to baskets may also be removed from baskets and reinstalled in other baskets.

 

The use of Mode S transponders require a 24-bit code to match the envelope registration marking for each flight, but given that baskets and fitted transponders frequently alternate between balloon envelopes, there is reasonable and ongoing commensurate risk that coding errors could be made, therefore, reducing aviation safety. The operator’s balloons are currently fitted with Mode A/C transponders that do not have the requirement for a 24-bit code but still allow visibility on air traffic control radar and by other aircraft equipped with traffic advisory systems.

 

The operator operates 1 balloon registered after 6 February 2014 which is not compliant with the requirements of paragraph 9E.2 of CAO 20.18. The other balloon in the operator’s fleet was registered before 6 February 2014 but is, nevertheless, captured within the scope of paragraph 9E.2 by virtue of having its transponder replaced (that is, swapped with another balloon) on or after 6 February 2014 without being compliant with the Mode S transponder requirements.

 

The operator has requested an exemption from the requirements of paragraph 9E.2 for its fleet of balloons. CASA has, in consultation with Airservices Australia, assessed the operator’s safety case and considers that the exemption will have no significant adverse safety impact, but rather reduces the complexity of the operator’s ballooning operations and the risk of transponder coding errors. The operator’s balloons will have at all times an operative Mode A/C transponder.

 

Instrument

CASA EX12/16 applies to the operator’s balloon aircraft mentioned in Schedule 1 of the instrument. The instrument exempts the aircraft from complying with the Mode S transponder requirements in paragraph 9E.2 of CAO 20.18.

 

The exemption is subject to the condition that a person using the aircraft must ensure that all I.F.R. flight plans in Australian airspace are annotated with the words RMK/CASA MODE S EXEMPT in Item 18 of the flight plan. A note has been inserted to advise that the Airservices Australia automated systems will reject a flight plan lodged for these aircraft without this annotation.

 

Legislative Instruments Act 2003 (the LIA)

Under regulation 5A of CAR 1988, if CASA has issued a CAO, and CASA later issues an exemption that affects the operation of the CAO, the later document is declared to be a disallowable instrument. Under subparagraph 6 (d) (i) of the LIA, an instrument is a legislative instrument for section 5 of the LIA if it is declared to be a disallowable instrument under legislation in force before the commencement of the LIA. CAR 1988 was in force before the commencement of the LIA.

 

This instrument affects the operation of paragraph 9E.2 of CAO 20.18 and is, therefore, a legislative instrument, subject to tabling and disallowance in the Parliament under sections 38 and 42 of the LIA.

 

Consultation

The operator has requested this instrument and has provided CASA with a satisfactory safety case. CASA has consulted Airservices Australia on the proposed operations and exemption. It is CASA’s view that no further consultation under section 17 of the LIA is necessary or appropriate.

 

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 instrument 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 instrument has been made by the Director of Aviation Safety, on behalf of CASA, in accordance with subsection 73 (2) of the Act.

 

The instrument commences on the day of registration and expires at the end of December 2018, as if it had been repealed by another instrument.

Attachment 1

Statement of Compatibility with Human Rights

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

 

Exemption — aircraft operating without carriage of Mode S transponder equipment (Goldrush Ballooning)

 

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 exempts specified balloon aircraft operated by Goldrush Ballooning Pty Ltd (the operator) from compliance with paragraph 9E.2 of Civil Aviation Order 20.18, which requires the aircraft to be equipped with a serviceable Mode S transponder that meets specified standards.

 

The purpose of the instrument is to allow the operator and persons using the aircraft to continue to operate the aircraft without meeting equipment requirements that, due to the nature of the operator’s ballooning operations (such as switching transponders and baskets between different balloon envelopes), would increase the risk of transponder coding errors. The exemption is subject to a condition imposed in the interests of aviation safety.

 

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.

Civil Aviation Safety Authority

Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to ensure the safety of air navigation in Australia, and provide a framework for the Civil Aviation Safety Authority (CASA) to issue regulations and orders that support this objective. CASA EX12/16 is an exemption instrument issued under section 11.160 of the CASR 1998, which allows CASA to exempt certain aircraft from specific provisions of Civil Aviation Orders (CAO) if it is satisfied that the exemption will not significantly impact aviation safety. This exemption specifically addresses the problem of transponder coding errors for Goldrush Ballooning Pty Ltd, a hot air balloon operator whose unique operational practices involve swapping baskets and transponders between different balloon envelopes, potentially increasing the risk of coding errors. The exemption aims to streamline the operator's operations while maintaining safety by ensuring that all Instrument Flight Rules (IFR) flight plans are annotated with "RMK/CASA MODE S EXEMPT." This legislative instrument is compatible with human rights, as it does not engage any of the applicable rights or freedoms recognised in the international instruments listed in the Human Rights (Parliamentary Scrutiny) Act 2011.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR 1998) include provisions that permit the Civil Aviation Safety Authority (CASA) to grant exemptions from certain requirements under the Civil Aviation Order (CAO) 20.18, which mandates that aircraft operating in specific airspaces or altitudes must carry a serviceable Mode S transponder. CASA EX12/16 applies specifically to Goldrush Ballooning Pty Ltd, a Melbourne-based hot air balloon operator, and exempts their specified balloon aircraft from the Mode S transponder requirements under paragraph 9E.2 of CAO 20.18. This exemption is intended to accommodate the unique operational practices of the operator, which involve frequently swapping baskets and transponders between different balloon envelopes, thereby reducing the risk of transponder coding errors that could compromise aviation safety. The exemption is contingent upon the condition that all flight plans in Australian airspace for these aircraft must be annotated with the words “RMK/CASA MODE S EXEMPT” in Item 18 of the flight plan. This legislative instrument is in force from its registration and expires at the end of December 2018, subject to parliamentary disallowance under the Legislative Instruments Act 2003. Additionally, the exemption has been assessed for compatibility with human rights, with the conclusion that it does not engage any applicable rights or freedoms.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) provide the framework under which the Civil Aviation Safety Authority (CASA) can grant exemptions from certain provisions of Civil Aviation Orders (CAO) that affect the safe navigation and operation of aircraft. Specifically, section 11.160(1) of the CASR 1998 allows CASA to grant an exemption from CAO provisions if it is satisfied that the exemption will not have a significant adverse safety impact. This authority is exercised under section 98 of the Civil Aviation Act 1988 (the Act). In this case, CASA EX12/16 is an exemption instrument issued for Goldrush Ballooning Pty Ltd, which operates a fleet of hot air balloons that do not comply with the Mode S transponder requirements set out in paragraph 9E.2 of CAO 20.18. The exemption allows the operator to continue its operations without the need to carry a serviceable Mode S transponder, as long as all Instrument Flight Rules (IFR) flight plans in Australian airspace are annotated with "RMK/CASA MODE S EXEMPT" in Item 18 of the flight plan. Under this exemption, Goldrush Ballooning Pty Ltd is required to ensure that their aircraft remain compliant with all other safety regulations and operational requirements, except for the specific requirement to carry a Mode S transponder. This means that while the balloons are exempt from carrying the transponder, they must still adhere to all other safety protocols and operational standards to ensure the safety of passengers and crew. The exemption is also subject to the condition that any flight plans submitted for these aircraft must include the specified annotation to alert air traffic control of the exemption status. Failure to comply with the conditions of the exemption, such as not annotating the flight plans appropriately, could result in civil or criminal penalties. Under the Civil Aviation Act 1988, non-compliance with CASA regulations can lead to enforcement actions, including fines and potential prosecution. The specific penalties for non-compliance with flight plan requirements or other operational regulations would be determined based on the nature and severity of the breach. Additionally, the exemption is subject to disallowance by Parliament under the Legislative Instruments Act 2003, which provides a mechanism for parliamentary scrutiny of such instruments. In summary, CASA EX12/16 provides Goldrush Ballooning Pty Ltd with a specific exemption from the Mode S transponder requirements for its hot air balloons, subject to certain conditions designed to maintain aviation safety. The exemption is a carefully considered measure that balances the operator's operational needs with the overarching goal of ensuring safe air navigation and operation.
