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 Civil Aviation Safety Authority or its predecessors issued AD/GOV/5 affecting Woodward Propeller Governors used on AiResearch TPE 331 engines. CASA has assessed this AD and as a result has cancelled Australian AD/GOV/5. The cancellation will become effective on 9 April 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation and establish regulations governing civil aviation. This legislation empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation, delegating authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. ADs, which are legislative instruments under the Legislative Instruments Act 2003, serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, in accordance with Annex 8 of the Convention on International Civil Aviation. In the context of Australia's obligations under this international convention, CASA has the responsibility to assess and, if necessary, issue Australian ADs when required by the State of Design. The regulatory process, however, does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These regulations apply to all persons and entities involved in the operation and maintenance of aircraft within Australia, including aircraft manufacturers, operators, and maintenance service providers. ADs are regulatory instruments that mandate specific actions or conditions to address safety concerns identified with particular types of aircraft or aeronautical products. Under regulation 39.001 of the Civil Aviation Safety Regulations, CASA has the authority to issue these directives, which must be consistent with Australia's international obligations under the Convention on International Civil Aviation, particularly Annex 8, which deals with airworthiness of aircraft. The ADs are intended to ensure the continuing airworthiness of aircraft registered in Australia by aligning with directives issued by the State of Design. The scope of these regulations extends nationally, covering all aircraft registered in Australia, regardless of their operation within state borders or internationally. The application of these regulations is not restricted by thresholds but is contingent on the identification of safety issues by CASA or foreign authorities. The ADs are legislative instruments that require parliamentary disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The process for issuing, amending, or cancelling ADs does not typically involve public consultation, as they are considered to not require a Regulatory Impact Statement, although they are subject to the scrutiny of the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations that serve the Act's objectives and promote the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are integral to maintaining the safety and airworthiness of aircraft, as they provide critical information and requirements that must be followed to ensure safe operation. Subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus, it is considered a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design, which is the country where the aircraft type was designed, has the overarching responsibility for the continuing airworthiness of that aircraft type. This includes providing necessary information to the State of Registry to ensure that the aircraft remains airworthy. Conversely, the State of Registry, which is the country where the individual aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. When an AD is issued by the State of Design, CASA must evaluate this information and, if deemed appropriate, issue an Australian AD to enforce the requirements set forth by the State of Design. This ensures that all aircraft registered in Australia comply with the necessary safety standards.
Breaches of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to serious consequences. Although the specific offences and penalties are not detailed within the explanatory statement, it is evident that non-compliance with airworthiness directives could result in significant civil or criminal penalties. Given the critical nature of air safety, any failure to adhere to these regulations can potentially lead to severe repercussions, including fines, imprisonment, or both, depending on the severity of the breach and its impact on public safety. The stringent nature of these regulations underscores the importance of adhering to airworthiness directives to maintain the highest safety standards in the aviation industry.
