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/ROBIN/18 Amendment 1 to correct an unsafe situation on Robin aircraft. The original issue corrected an unsafe condition associated with the occupants safety harness for a particular HR100 model. The original issue of the Airworthiness Directive was applied to a particular model of aircraft; however, the unsafe condition actually affects all models of the HR100 aircraft type. This amendment expands the applicability to all HR 100 models. The State of Design for this type, France, has not yet taken action to correct this unsafe condition. As there are some examples of the HR100 on the Australian register, CASA has developed an AD to correct the problem on Australian aircraft.
CASA has not consulted with the Australian industry and public. The amendment to the Airworthiness Directive is to correct an administrative error.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the General Manager, Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to regulate civil aviation safety and industry standards within Australia. The Act was introduced to address the need for comprehensive safety regulations and industry oversight, particularly in relation to airworthiness and operational standards. One significant component of the Act is the authority it grants to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, as outlined in the Civil Aviation Safety Regulations 1998. These directives are critical in maintaining the continuing airworthiness of aircraft, ensuring that any safety issues identified are promptly addressed. Under the authority of the Act, CASA issued Airworthiness Directive AD/ROBIN/18 Amendment 1 to correct an unsafe condition affecting Robin HR100 aircraft. This directive was necessitated by an oversight in the original directive that failed to encompass all HR100 models, thereby expanding its scope to rectify this safety issue. The policy objective underpinning this directive is to ensure the safety of aircraft operating within Australia by correcting the identified unsafe condition.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) under regulation 39.001, empowering the Civil Aviation Safety Authority (CASA) to mandate safety measures for specified types of aircraft or aeronautical products. This legislation applies to any aircraft or aeronautical products registered in Australia, thereby impacting the aviation industry and aircraft operators within the country. The authority to issue these directives is exercised to ensure the safety of air navigation, which is crucial for maintaining the integrity and safety standards of Australian airspace. The regulatory reach of these directives is confined to the national level, with CASA acting as the national airworthiness authority. While the Act and its regulations are comprehensive in addressing safety concerns, they do not specify exclusions or exemptions for the issuance of ADs, ensuring that safety measures are universally applied. The application of these regulations may be extended or clarified through subordinate instruments, which adhere to the legislative framework set by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998.
Key Provisions
The key provisions of the Civil Aviation Safety Regulations 1998, as referenced in regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make these regulations in the interest of air navigation safety, and subregulation 39.001(5) confirms that such ADs are disallowable instruments under the Acts Interpretation Act 1901. This means that ADs are legislative instruments, subject to certain scrutiny and review processes.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to act on information provided by the State of Design concerning continuing airworthiness. When an AD is issued by the State of Design for a type of aircraft registered in Australia, CASA must assess this information and, if necessary, issue its own AD to ensure compliance with the State of Design's requirements. This ensures that the continuing airworthiness of aircraft registered in Australia is maintained in line with international standards set out in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft and must act promptly upon receiving information from the State of Design.
There are no specific offences or penalties outlined in the regulations for failure to comply with ADs; however, non-compliance could potentially result in severe safety implications, including the risk of accidents or incidents involving aircraft. CASA’s issuance of ADs is aimed at preventing such unsafe conditions from occurring, and operators must comply with these directives to maintain the airworthiness of their aircraft. While the regulations do not specify civil or criminal penalties for non-compliance, the overarching legal framework of the Civil Aviation Act 1988 and other related laws could impose sanctions for breaches of aviation safety regulations.
