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/FN-333/2 affecting SIAI Marchetti FN-333 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/FN-333/2. The cancellation will become effective on 4 June 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, enacted by the Australian Parliament, was established to provide a comprehensive legal framework governing civil aviation in Australia. This Act serves to ensure the safety and efficiency of civil aviation operations within the country, aligning with international standards set by the International Civil Aviation Organization (ICAO). One of its key provisions allows the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which include the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments designed to maintain and ensure the continuing airworthiness of aircraft, as mandated under international agreements like Annex 8 to the Convention on International Civil Aviation. The policy objective of these regulations is to uphold high safety standards in the Australian civil aviation sector, ensuring compliance with both national and international obligations.
Scope and Application
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) aimed at ensuring the safety of air navigation. These ADs apply to specific kinds of aircraft or aeronautical products, and they are legislative instruments as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The authority to issue ADs stems from Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design of an aircraft type is responsible for ensuring its continuing airworthiness, while the State of Registry, in this case CASA, must implement these requirements domestically. This particular AD/FN-333/2, affecting SIAI Marchetti FN-333 model aeroplanes, has been cancelled by CASA following the assessment that the unsafe condition no longer exists, with no replacement AD required. This cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation and, as such, did not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, authorises the Governor-General to create regulations that serve the Act's objectives and enhance air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulatory power is further clarified in subregulation 39.001(5), which aligns ADs with disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per the Legislative Instruments Act 2003.
Under these provisions, the State of Design of an aircraft bears the primary responsibility for ensuring the aircraft's continuing airworthiness, as stipulated in Annex 8 of the Convention on International Civil Aviation. This responsibility includes providing necessary information to the States of Registry to maintain airworthiness. Similarly, the State of Registry must establish or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the State of Design's requirements.
CASA has issued and subsequently cancelled AD/FN-333/2 for SIAI Marchetti FN-333 model aeroplanes, a decision grounded in Australia's obligations under the Convention on International Civil Aviation. The cancellation of this AD, effective from 4 June 2009, reflects the resolution of the previously identified unsafe condition, thus eliminating the need for a replacement AD. Given that the cancellation results from international obligations rather than domestic consultation, no public consultation or Regulatory Impact Statement has been required. This AD was issued by the Manager Systems and New Technologies within CASA's Airworthiness Engineering Group, in accordance with subsection 84A(2) of the Act.
The Civil Aviation Safety Regulations 1998 impose several obligations on the parties involved. Firstly, CASA must rigorously assess any AD issued by a State of Design to determine its relevance and necessity for Australian-registered aircraft. This assessment is crucial to ensure that the safety standards set forth in the AD are appropriately enforced in Australia. Secondly, the State of Registry, in this case CASA, must take proactive steps to ensure that the continuing airworthiness of aircraft is maintained through the implementation of required ADs. Failure to comply with these obligations could lead to safety deficiencies, potentially resulting in accidents or incidents.
In terms of consequences for non-compliance, the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties for breaching ADs. However, the overarching Civil Aviation Act 1988 provides a framework for enforcing compliance through potential civil or criminal penalties. For example, non-compliance with ADs could lead to significant fines or imprisonment under the general provisions of the Act. Such penalties underscore the importance of adhering to airworthiness directives to maintain the high safety standards expected in civil aviation.
