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 Unites States FAA issued AD 2008-02-14, affecting Boeing 767 series aircraft, in 2008. The United States is the State of Design for these types. As a result of a request from industry, CASA has amended the equivalent Australian AD to correct a typographical error. The amended AD, AD/B767/237 Amendment 1, will become effective on 8 May 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 Acting Manager, Systems and New Technologies 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 by the Australian Parliament to regulate civil aviation safety and to establish the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. This Act was introduced to address the need for a comprehensive framework governing the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to make regulations that serve the interests of safe air navigation, with regulation 39.001 specifically enabling CASA to issue airworthiness directives (ADs) for types of aircraft and aeronautical products. These ADs are legislative instruments and are integral to ensuring the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The policy objective is to maintain the highest standards of aviation safety, which involves the timely issuance of ADs in response to international standards and national requirements.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, outlines the framework for the regulation of civil aviation in Australia, particularly focusing on the safety aspects of air navigation. Under this framework, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are instrumental in maintaining the continuing airworthiness of aircraft. These directives are legislative instruments subject to disallowance and are made in accordance with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The ADs are intended to ensure that aircraft remain in a condition that is safe for operation, reflecting the obligations of the State of Design and the State of Registry. The ADs issued by CASA are based on directives from the State of Design and are applicable to aircraft registered in Australia. These regulations apply to all relevant entities and individuals involved in the operation and maintenance of aircraft within Australia, ensuring adherence to both national and international safety standards. The issuance of ADs does not require public consultation as it is aligned with international obligations and is based on technical assessments rather than regulatory impact considerations.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998 (regulation 39.001) permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring their continuing airworthiness in line with the Civil Aviation Act 1988 (section 98). These ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901 (section 46A). The issuing process of an AD follows the guidelines provided in Annex 8 to the Convention on International Civil Aviation, where the State of Design has primary responsibility for an aircraft type’s airworthiness. Upon receiving an AD from the State of Design, CASA must review and, if necessary, issue a corresponding Australian AD to enforce the safety measures outlined by the State of Design.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA include the assessment of airworthiness directives issued by the State of Design. CASA must ensure that any necessary adjustments or amendments are made to align with Australian regulations before issuing an Australian AD. This obligation is underscored by the need for CASA to maintain the highest safety standards in accordance with international conventions and Australian legislation. Furthermore, CASA must ensure that any ADs issued are clear, accurate, and effectively communicate the required safety measures to the relevant parties. This includes keeping the ADs updated and ensuring they replace or cancel previous versions as needed.
Breaches of the airworthiness directives issued under the Civil Aviation Safety Regulations 1998 can lead to serious civil or criminal consequences. Operators who fail to comply with the mandated safety measures outlined in an AD may face penalties, including fines and imprisonment. The exact penalties depend on the severity of the breach and the specific regulations involved. Non-compliance with ADs can compromise the safety of air navigation, leading to potential accidents and endangering lives. Therefore, it is crucial for all stakeholders to adhere to the directives to maintain the high safety standards expected in civil aviation.
