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 US FAA has issued AD 2005-19-25 affecting Boeing 737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/249, which will become effective on 24 November 2005.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the 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 was enacted to provide a legislative framework for civil aviation in Australia, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety. One such regulation is found in the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives are instrumental in maintaining the continuing airworthiness of aircraft, a responsibility that aligns with international obligations under the Convention on International Civil Aviation, particularly Annex 8. The ADs serve as a common form of continuing airworthiness information and are issued by most ICAO Contracting States. The ADs, being legislative instruments, must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of the Act, the Governor-General can make regulations for the purposes of the Act, and regulation 39.001 specifically grants CASA the authority to issue ADs for certain kinds of aircraft or aeronautical products. These ADs are legislative instruments, as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness with the State of Design, and mandates that the State of Registry must implement requirements to maintain airworthiness. The ADs are a form of continuing airworthiness information, ensuring compliance with international standards and obligations, particularly when responding to directives from the State of Design, such as the US Federal Aviation Administration’s AD 2005-19-25 for Boeing 737 aircraft, which CASA has assessed and issued as AD/B737/249 for Australia. This regulatory process does not involve public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products (s 39.001). These ADs, which are legislative instruments (s 46A Acts Interpretation Act 1901), are a crucial mechanism for ensuring the ongoing airworthiness of aircraft. They are typically issued in response to safety concerns identified by the State of Design, which holds the primary responsibility for the continuing airworthiness of an aircraft type (Annex 8, Convention on International Civil Aviation). Once an AD is issued by a State of Design, such as the US Federal Aviation Administration (FAA) for a Boeing 737 model, CASA, as Australia's national airworthiness authority, is obligated to review this information and, if necessary, issue an Australian AD to enforce the same requirements domestically.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties and entities governed by these directives are significant. CASA must assess the relevance and necessity of any foreign ADs issued by the State of Design for aircraft types registered in Australia. If deemed appropriate, CASA is required to issue a corresponding Australian AD to ensure compliance with international safety standards (Annex 8, Convention on International Civil Aviation). This process underscores the importance of harmonising national regulations with international obligations to maintain a consistent safety framework across jurisdictions.
Breaching the requirements set out in an AD can lead to serious consequences, both civil and criminal. Civil penalties may include fines and other monetary penalties as stipulated by the regulations, while criminal penalties can result in imprisonment, depending on the severity of the breach. The maximum penalties for violations are not explicitly stated in the provided text, but they are likely to be severe, reflecting the critical nature of air safety regulations. Non-compliance with ADs can also result in the grounding of aircraft, which can have significant operational and financial implications for airlines and other operators.
The process for issuing ADs, as outlined in the Civil Aviation Safety Regulations 1998, does not require public consultation or a Regulatory Impact Statement, given their urgent nature and the necessity to align with international safety protocols (Office of Regulatory Review). This streamlined process ensures that safety directives can be implemented swiftly to address emerging issues without unnecessary delays. The AD issued by CASA in response to the FAA's AD 2005-19-25, for example, was assessed and implemented in a timely manner to maintain the safety standards of Boeing 737 aircraft operating in Australia.
