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/CESSNA 310/40 affecting Cessna 310R aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/40. The cancellation will become effective on 13 March 2008. 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 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 to provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing the need for a cohesive set of rules to ensure safety and efficiency within the sector. One of the key mechanisms under this Act is the issuance of airworthiness directives (ADs), which are governed by the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, ensuring compliance with safety standards. The Civil Aviation Act 1988 was introduced by the Australian Parliament to create a robust legislative foundation that aligns with international standards, particularly those set by the Convention on International Civil Aviation. The primary policy objective is to maintain the highest possible safety standards in civil aviation, reflecting Australia’s commitment to international obligations and the protection of public safety.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) within Australia, aimed at ensuring the safety of air navigation. Under this Act, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specified types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and they are also considered legislative instruments under the Legislative Instruments Act 2003. The State of Design, which is the country where the aircraft type is designed, holds primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA as Australia's national airworthiness authority, is responsible for ensuring the continuing airworthiness of individual aircraft registered in Australia. When a State of Design issues an AD, CASA must review this information and, if necessary, issue a corresponding Australian AD. In this particular instance, CASA issued AD/CESSNA 310/40 for Cessna 310R aircraft, which has now been cancelled effective 13 March 2008 due to the unsafe condition no longer existing. This cancellation aligns with Australia's obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This regulatory power is crucial in maintaining the safety and airworthiness of aircraft. Furthermore, subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and by virtue of section 6 of the Legislative Instruments Act 2003, ADs are recognised as legislative instruments.
These regulations impose clear obligations on CASA and other entities involved in the management of aircraft airworthiness. CASA, as Australia’s national airworthiness authority, must ensure the continuing airworthiness of aircraft registered in Australia. This involves assessing information provided by the State of Design and, if necessary, issuing corresponding Australian ADs to enforce the required safety measures. The State of Design has the overarching responsibility to ensure the continuing airworthiness of an aircraft type, including providing necessary information to States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. States of Registry, on the other hand, are tasked with developing or adopting requirements to ensure the airworthiness of the aircraft they register.
Failure to comply with ADs or the regulations governing them can result in serious consequences. Although specific offences, penalties, or civil/criminal consequences are not detailed in the text, it is implied that non-compliance with airworthiness directives could lead to safety violations. Such violations could potentially result in legal action, fines, or other penalties under Australian law. Given the critical nature of air safety, adherence to ADs is mandatory, and any breach could have severe repercussions, including potential grounding of aircraft or other enforcement actions by CASA.
In the specific case of AD/CESSNA 310/40 affecting Cessna 310R aircraft, CASA has assessed the AD and determined that it should be cancelled due to the resolution of the unsafe condition. The cancellation, effective from 13 March 2008, means that no replacement AD is required. This decision aligns with Australia’s obligations under the Convention on International Civil Aviation and was made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA. The process for issuing and cancelling ADs, while technical and detailed, is governed by strict regulatory frameworks to ensure the highest safety standards in civil aviation.
