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 raised AD/GENERAL/4 Amendment 3 to correct an unsafe situation on all types of aircraft in 1996. The AD prescribes requirements to be met by aircraft exits. As a result of a request from industry, and an internal review, CASA has issued AD/GENERAL/4 amendment 4 which becomes effective on 30 July 2009 to clarify some requirements and to align it with international practice. The effect of the changes is to reduce the regulatory burden on the Australian industry. This AD cancels and replaces the previous issue.
CASA has not consulted with the Australian industry and public because the amendment reduces the regulatory burden and aligns the AD with international requirements.
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 & Structures 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 the safety of air navigation and the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to address specific safety issues concerning types of aircraft or aeronautical products. These directives are instrumental in ensuring that aircraft maintain their airworthiness in accordance with international standards. The Act and its regulations are designed to ensure the safety of air navigation, thereby protecting the public and maintaining the integrity of the aviation industry.
The Civil Aviation Safety Regulations 1998 provide that ADs are legislative instruments that can be disallowed under the Acts Interpretation Act 1901, reflecting the importance of these directives in maintaining safety standards. CASA has the responsibility to assess and implement ADs issued by the State of Design, aligning them with international practices and reducing any undue regulatory burden on the industry. The AD/GENERAL/4 Amendment 4, issued by CASA to address safety concerns related to aircraft exits, exemplifies this process by clarifying requirements and aligning with international standards. The amendment was made without public consultation as it aims to streamline regulations and is considered a routine safety measure.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory framework applies to all aircraft registered in Australia and those operating within Australian airspace, ensuring adherence to safety standards. ADs are legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if necessary, issue corresponding ADs to maintain airworthiness. For instance, AD/GENERAL/4 Amendment 3, initially issued in 1996, was updated to Amendment 4 on 30 July 2009, to address an unsafe situation and clarify requirements, thereby reducing regulatory burden and aligning with international standards. This amendment was made without public consultation as it aligns with international practices and reduces the burden on the industry. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, grants the Governor-General the authority to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, as per section 6 of the Legislative Instruments Act 2003, they are legislative instruments. These directives serve as the primary means of continuing airworthiness information, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is the state where the aircraft type is designed, has the primary responsibility for the continuing airworthiness of an aircraft type, and it must provide necessary information to the appropriate States of Registry to maintain this airworthiness.
The Civil Aviation Act 1988 and the accompanying regulations impose several obligations on the entities they govern. Firstly, the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type. This includes issuing ADs to address any unsafe conditions identified. Secondly, the State of Registry, which is the state where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. CASA must also ensure that these directives align with international standards and practices. The obligations extend to ensuring that these directives do not unnecessarily increase the regulatory burden on the industry, as evidenced by CASA's issuance of AD/GENERAL/4 Amendment 4 to clarify requirements and align with international practice.
Breaches of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various consequences. Failure to comply with ADs can lead to significant safety risks, potentially resulting in accidents or incidents. While the specific penalties for non-compliance are not detailed in the provided text, it is known that CASA can take enforcement actions against entities that fail to adhere to the directives. This could include fines, suspension of airworthiness certificates, or other regulatory measures. Additionally, there could be civil liabilities for any damages resulting from accidents caused by non-compliance. The severity of the penalties would depend on the extent of the breach and its impact on aviation safety.
