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 United States FAA has issued AD 2003-03-15 affecting Boeing model 737 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/255, which will become effective on 22 December 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, New Technologies and Systems, 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 the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations that serve the interests of safety in air navigation, and these regulations can include the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower CASA to issue ADs for certain types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901. These ADs are critical in maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, in accordance with Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, must respond to ADs issued by the State of Design and may issue corresponding Australian ADs to enforce these requirements. This process ensures that Australian aviation aligns with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework within which airworthiness directives (ADs) are issued in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products, thereby ensuring that safety standards are upheld in the interests of air navigation. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are integral to maintaining the continuing airworthiness of aircraft, a responsibility that lies with the State of Design for the aircraft type and the State of Registry for individual aircraft. In practice, CASA, as Australia's national airworthiness authority, must assess and issue Australian ADs when required by the State of Design, such as in the case of the Boeing 737 AD issued by the United States Federal Aviation Administration, which CASA has assessed and adapted as AD/B737/255 for Australian application. This process adheres to international obligations under the Convention on International Civil Aviation, and the specific ADs do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are legislative instruments under section 6 of the Legislative Instruments Act 2003, and they serve as a means for ensuring the continuing airworthiness of aircraft types as mandated by Annex 8 to the Convention on International Civil Aviation. In the case of foreign ADs affecting aircraft registered in Australia, CASA is obligated to assess the information and, if necessary, issue an Australian AD to implement the requirements stipulated by the State of Design.
Entities governed by these regulations, particularly aircraft operators and maintenance providers, must comply with any ADs issued by CASA. This includes adhering to the specific maintenance, repair, or operational requirements outlined in the ADs to ensure the safety and airworthiness of the aircraft. Operators must also ensure that their aircraft meet the necessary standards and are maintained in accordance with the directives. CASA mandates that all ADs be followed to maintain safety standards consistent with international conventions.
Failure to comply with an AD can result in serious legal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions by CASA. The penalties for such non-compliance can include fines and, in severe cases, the grounding of the aircraft. The maximum penalties for breaches of safety regulations are stipulated under section 44 of the Civil Aviation Act 1988, which can reach up to $222,200 for individuals and higher for corporations, reflecting the critical nature of maintaining airworthiness standards. Ensuring compliance with ADs is therefore not only a regulatory obligation but also a safety imperative.
