CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
CASA issued AD/BAL/13 to correct an unsafe condition on Hot Air Balloons. As a result of a request from industry, CASA has amended this AD to remove the maintenance requirements for the AD as it is duplicative to the Maintenance regulation requirements. The amended AD, AD/BAL/13 Amendment 1, will become effective on 6 August 2010. This AD cancels and replaces the previous issue.
CASA has not consulted with the Australian industry and public because the change is an administrative amendment.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Continuing Airworthiness, Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to regulate civil aviation within Australia, aiming to ensure safety and efficiency in air navigation. This Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 are implemented, enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives to maintain the safety standards of aircraft and aeronautical products. These directives are integral in ensuring that all aircraft meet the required safety standards, thereby addressing potential safety gaps that could arise from design or operational issues. CASA, as Australia's national airworthiness authority, plays a crucial role in assessing and mandating continuing airworthiness requirements derived from international standards, thus ensuring compliance with both national and international safety regulations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, which are legislative instruments designed to ensure the continuing airworthiness of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act and in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives are necessary to address any unsafe conditions identified and are a common form of continuing airworthiness information as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case CASA, has the responsibility to ensure that the aircraft's continuing airworthiness aligns with international standards and practices. This particular AD, AD/BAL/13 Amendment 1, was issued to correct an unsafe condition on hot air balloons and, following an industry request, was amended to remove duplicative maintenance requirements. The amendment became effective on 6 August 2010 and replaces the previous directive. Given that this amendment is administrative in nature, CASA did not consult with industry or the public, and the Office of Regulatory Review determined that it does not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety of air navigation in Australia, with particular focus on the issuance of airworthiness directives (ADs). Section 98 of the Act authorises the Governor-General to make regulations for the purposes of the Act, with regulation 39.001 specifically allowing the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products (s 39.001). These directives are legislative instruments, as they are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and fall under the definition of legislative instruments in the Legislative Instruments Act 2003 (s 6).
The obligations imposed by the Act and Regulations on CASA and other entities are significant. CASA, as Australia's national airworthiness authority, is tasked with ensuring the continuing airworthiness of aircraft registered in Australia. This includes assessing information from the State of Design, which has overall responsibility for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation, and issuing Australian ADs as necessary (s 39.001, Annex 8). The State of Registry, which in Australia is CASA, must also develop or adopt requirements to ensure the continuing airworthiness of individual aircraft (Annex 8).
Failure to comply with an AD can lead to serious consequences. Although the specific penalties for non-compliance are not detailed in the text, breaches of ADs generally result in administrative actions, including fines or other enforcement measures under the Civil Aviation Act 1988 or the Civil Aviation Safety Regulations 1998. Non-compliance can also lead to more severe outcomes, such as grounding of aircraft or other safety-related actions by CASA. The amended AD/BAL/13 Amendment 1, which removes duplicative maintenance requirements for hot air balloons, aims to streamline compliance while maintaining safety standards.
The process of issuing ADs is overseen by CASA and is subject to certain administrative requirements. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement, indicating that the changes are administrative and do not necessitate a broader impact assessment. The ADs are issued by the Manager, Continuing Airworthiness, Airworthiness and Engineering Branch, on behalf of CASA, in accordance with the authority granted under subsection 94(1) of the Act. This ensures that the directives are made within the legal framework provided by the Act and Regulations.
