Exemption — aircraft operating without carriage of Mode S transponder equipment (Picture This 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.

 

Under subsection 33 (3) of the Acts Interpretation Act 1901, where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character (including rules, regulations or by-laws), the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal, rescind, revoke, amend, or vary any such instrument.

 

Background

Picture This 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 balloons in the operator’s fleet were registered before 6 February 2014 but are, nevertheless, captured within the scope of paragraph 9E.2 by virtue of having their transponders replaced (that is, swapped with another balloon) on or after 6 February 2014 without being compliant with the Mode S transponder requirements.

 

The operator requested an exemption from the requirements of paragraph 9E.2 for balloon operations. CASA EX14/16 was issued on 20 January 2016 for this purpose, limited to the balloons in the operator’s fleet. However, the operator has since requested that CASA extend the scope of the exemption to apply to any balloon operated by the operator to allow for future additions to the operator’s fleet. CASA has considered the operator’s proposal and agrees that the intent of the exemption would not be diminished and there would be no significant adverse safety impact. The exemption would lead to a reduction in costs and operational complexity for the operator. The operator’s balloons will have at all times an operative Mode A/C transponder.

 

Instrument

CASA EX38/16 repeals and replaces CASA EX14/16, and applies to all balloons operated by the operator. The instrument exempts the operator’s balloons from complying with the Mode S transponder requirements in paragraph 9E.2 of CAO 20.18.

 

The exemption is subject to the condition that the operator must ensure that an exempted balloon carries a serviceable Mode A/C transponder in order for air traffic control to locate the balloon. It is also a condition that the operator must ensure all I.F.R. flight plans for the balloons operating 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 revised exemption and has provided CASA with a satisfactory safety case. CASA consulted Airservices Australia on the proposed operations and the original 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

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 all balloons operated by Picture This 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 balloons to continue to operate the balloons 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 conditions 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 civil aviation in Australia. The CASR 1998 empower the Civil Aviation Safety Authority (CASA) to issue regulations that govern the safe operation of aircraft, including the mandatory carriage of certain equipment such as Mode S transponders. The issue of the legislation was to provide a clear legal framework for the operation of aircraft, ensuring that all operations met safety standards as set by CASA. The instrument CASA EX38/16 was introduced by CASA in response to a request by Picture This Ballooning Pty Ltd for an exemption from the requirement to carry Mode S transponders on their hot air balloons. This exemption addresses the operational challenges faced by the company, which frequently swaps baskets and transponders between different balloon envelopes, potentially leading to coding errors and compromising safety. The exemption allows the operator to continue operations without the need for Mode S transponders, subject to certain safety conditions, including the carriage of Mode A/C transponders and the annotation of flight plans. The instrument was made by the Director of Aviation Safety on behalf of CASA and is subject to disallowance by Parliament. The exemption does not engage any human rights issues and is compatible with the human rights recognised under the Human Rights (Parliamentary Scrutiny) Act 2011.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR 1998) outline the safety requirements for the operation of aircraft in Australian airspace, and the Civil Aviation Safety Authority (CASA) has the power to issue exemptions from certain requirements where it is safe to do so. Under regulation 11.160 of CASR 1998, CASA can grant an exemption from a Civil Aviation Order (CAO) if it relates to matters affecting the safe navigation and operation of aircraft. In this case, CASA has issued an exemption for Picture This Ballooning Pty Ltd, a Melbourne-based hot air balloon company, to operate its balloons without carrying a Mode S transponder. The exemption is applicable to all balloons operated by the company, including those registered before and after 6 February 2014, and is subject to certain conditions to ensure aviation safety. These conditions include ensuring that the balloons carry a serviceable Mode A/C transponder and that the flight plans are annotated with "RMK/CASA MODE S EXEMPT". The exemption is in force from the day of registration and will expire at the end of December 2018. The exemption is a legislative instrument that is subject to disallowance in Parliament under the Legislative Instruments Act 2003. The instrument was made in accordance with subsection 73(2) of the Civil Aviation Act 1988 and has been published on the Internet, as required by regulation 11.225 of CASR 1998. The exemption does not engage any of the applicable rights or freedoms, and a Statement of Compatibility with Human Rights has been prepared in accordance with Part 3 of the Human Rights (Parliamentary Scrutiny) Act 2011.

Key Provisions

The key provisions of CASA EX38/16 are found within the Civil Aviation Safety Regulations 1998 (CASR 1998) and the Civil Aviation Order 20.18 (CAO 20.18). The instrument itself, CASA EX38/16, exempts all balloons operated by Picture This Ballooning Pty Ltd from the requirements of paragraph 9E.2 of CAO 20.18, which mandates the use of a serviceable Mode S transponder (section 1). This exemption is granted due to the unique operational practices of the company, which involve frequently swapping baskets and transponders between different balloon envelopes, leading to a heightened risk of transponder coding errors (section 4). The exemption is subject to conditions, including the requirement for all exempted balloons to carry a serviceable Mode A/C transponder and for all flight plans to be annotated with "RMK/CASA MODE S EXEMPT" (section 1). Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is required to ensure that aircraft operating within Australian airspace meet specified safety standards. This includes the carriage of approved instruments and equipment, as outlined in CAO 20.18 (regulation 11.160). The exemption provided by CASA EX38/16 allows Picture This Ballooning Pty Ltd to operate its balloons without the need for Mode S transponders, provided that certain conditions are met. These conditions include the ongoing carriage of a serviceable Mode A/C transponder and the specific annotation in all flight plans (section 1). The operator must also ensure that all relevant safety considerations are addressed to maintain the safe navigation and operation of the balloons (regulation 11.225). Breaching the conditions of the exemption or failing to meet the specified safety requirements can lead to serious consequences. While CASA EX38/16 does not impose specific offences or penalties, any deviation from the stipulated conditions could result in CASA revoking the exemption. This, in turn, would require Picture This Ballooning Pty Ltd to comply with the Mode S transponder requirements of CAO 20.18. Non-compliance with the Civil Aviation Safety Regulations 1998, including the failure to carry approved equipment, can lead to enforcement actions by CASA, which may include fines, legal proceedings, or other regulatory measures. The exact penalties for non-compliance are detailed in the Civil Aviation Act 1988 and other relevant regulations (subsection 98(5A) of the Act, regulation 11.230).
