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 has raised AD/OH-58/8 to correct an unsafe situation on OH-58A variant helicopters. Requirements are introduced to inspect the main rotor mast for evidence of cracking and corrosion to prevent the loss of the helicopter. As Australia is the State of Design for variants of the OH-58A type, CASA is required to develop, and to transmit to other States of Registry, an AD to correct the problem.
CASA has not consulted with the Australian industry and public due to the urgent nature of the unsafe condition. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
Compatibility with human rights and freedoms
This 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.
Human Rights Implications
The instrument sets out technical requirements as detailed above. The instrument does not engage any of the applicable rights or freedoms.
Conclusion
The instrument is compatible with human rights and freedoms.
The AD has been made by the General Manager, Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the ongoing airworthiness of aircraft in Australian airspace. This legislative framework responds to the need for stringent safety measures in the aviation sector, addressing issues that could compromise the safety of aircraft operations. CASA's authority under section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows for the issuance of ADs, which are essential in maintaining safety standards in line with international obligations under ICAO conventions. The recent issuance of AD/OH-58/8, mandating inspections for cracking and corrosion in OH-58A variant helicopters, exemplifies the practical application of these regulations to rectify unsafe conditions swiftly. The AD was issued without prior consultation due to the urgency of the safety concern, and it aligns with international safety protocols, reflecting CASA's commitment to ensuring the safety and reliability of aircraft within its jurisdiction.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, pertain to the regulation and oversight of airworthiness in Australia. Specifically, under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to issue regulations that serve the interests of air navigation safety, with the Civil Aviation Safety Regulations 1998 being a key component of this framework. Regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, making ADs legislative instruments as per the Legislative Instruments Act 2003. These ADs are essential for ensuring the continuing airworthiness of aircraft and are consistent with international obligations under Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case CASA, is tasked with ensuring the safety of aircraft registered in Australia by implementing necessary directives. For example, AD/OH-58/8 was issued to address a safety issue with OH-58A variant helicopters, requiring inspections for cracks and corrosion in the main rotor mast to prevent potential loss of the aircraft. The urgent nature of this condition precluded consultation with industry and the public, and it has been determined that such ADs do not require a Regulatory Impact Statement. This legislative instrument is also compatible with human rights and freedoms as it does not engage any of the applicable rights or freedoms under the Human Rights (Parliamentary Scrutiny) Act 2011.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for issuing airworthiness directives (ADs) to ensure the safety of aircraft in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, with a primary focus on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
Under the ADs, CASA has the responsibility to ensure the continuing airworthiness of aircraft on the Australian Register. This includes assessing information provided by the State of Design—the country responsible for the design of the aircraft—and issuing Australian ADs to mandate necessary requirements. For instance, AD/OH-58/8 was issued to address an unsafe situation with OH-58A variant helicopters, requiring inspections of the main rotor mast for cracking and corrosion to prevent potential loss of the helicopter. In this case, CASA did not consult with the Australian industry and public due to the urgency of the unsafe condition.
Compliance with ADs is mandatory for all parties governed by the Civil Aviation Act 1988. Aircraft operators, manufacturers, and other relevant parties must adhere to the requirements specified in ADs to ensure the safety and airworthiness of their aircraft. Failure to comply with ADs can result in significant consequences, including potential safety hazards, fines, and other penalties. The Civil Aviation Safety Regulations 1998, as well as other related legislation, outline the specific obligations and requirements for compliance.
In terms of penalties, breaches of ADs can lead to both civil and criminal consequences. Civil penalties may include fines, which can vary depending on the severity of the breach. Additionally, CASA can take enforcement actions such as grounding of aircraft, suspension of airworthiness certificates, or even revocation of licenses. Under the Civil Aviation Act 1988, criminal penalties can also be imposed, including fines of up to $210,000 for individuals and $1,050,000 for bodies corporate, as well as imprisonment for serious offences. Ensuring compliance with ADs is crucial to maintaining the high safety standards expected in the aviation industry.
