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.
The European Aviation Safety Authority (EASA) has issued AD 2008-0156 affecting Eurocopter Deutschland MBB-BK117 model helicopters. EASA acts on behalf of Germany, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/GBK 117/6, Amendment 5, which will become effective on 02 September 2008. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish the legal framework for ensuring the safety of civil aviation in Australia. The Act empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation. Under section 98 of the Act, the Civil Aviation Safety Regulations 1998 were subsequently introduced to provide detailed regulatory provisions, including the issuance of airworthiness directives (ADs). These directives, which are legislative instruments, are critical for maintaining the continuing airworthiness of aircraft types registered in Australia, ensuring compliance with international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) is the national airworthiness authority responsible for assessing and issuing these directives, as mandated by the State of Registry obligations under Annex 8 of the Convention. This legislative approach ensures that Australia meets its international obligations and maintains high safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, apply to all aircraft registered in Australia and those operated by Australian entities, encompassing both commercial and private aviation activities. The scope extends to mandating airworthiness standards and procedures, ensuring compliance with international safety protocols, and overseeing the continuous airworthiness of aircraft types registered in Australia. This regulation is integral to maintaining the safety standards set forth under the Civil Aviation Act 1988 and the Convention on International Civil Aviation. Airworthiness Directives (ADs) issued under regulation 39.001 serve as legislative instruments, providing enforceable mandates that are critical for the safety of air navigation. ADs are often issued in response to identified safety concerns or modifications required for specific aircraft types, such as the Eurocopter Deutschland MBB-BK117 model helicopters addressed by AD 2008-0156 from the European Aviation Safety Authority. These directives, when adopted by the Civil Aviation Safety Authority (CASA), become binding on the operators of the affected aircraft in Australia, ensuring they meet the required safety standards. Notably, these ADs do not undergo public consultation or require a Regulatory Impact Statement as they are issued pursuant to Australia’s international obligations and in response to directives from the State of Design.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for issuing airworthiness directives (ADs) to ensure the safety of aircraft. Under section 98 of the Civil Aviation Act 1988, the Governor-General can make regulations to enhance air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulation is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003. Additionally, subregulation 39.001(5) specifies that ADs are disallowable instruments as defined in section 46A of the Acts Interpretation Act 1901. These ADs are integral to maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns responsibility to the State of Design for the airworthiness of aircraft types.
The obligations under the Civil Aviation Safety Regulations 1998 require CASA to closely monitor and respond to ADs issued by the State of Design, which in this case is Germany for the Eurocopter Deutschland MBB-BK117 model helicopters. CASA must assess the AD issued by the European Aviation Safety Authority (EASA) and, if necessary, issue an Australian AD to enforce the requirements. This process ensures that Australian-registered aircraft meet international safety standards. The State of Registry, which is Australia in this context, must also develop or adopt requirements to ensure the continuing airworthiness of aircraft. This means that CASA, as the national airworthiness authority, must ensure that Australian ADs align with international directives to maintain compliance with global safety standards.
Failure to comply with ADs can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties, including fines and potential legal action against the aircraft operator. The exact penalties are determined by the severity of the non-compliance and can vary significantly. Additionally, non-compliance can lead to the grounding of aircraft, which can have substantial financial and operational repercussions for airlines and aircraft operators. The enforcement of ADs is critical to preventing accidents and ensuring the safety of air travel.
