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/BEECH 90/64 affecting Beechcraft C90 and E90 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 90/64. The cancellation will become effective on 31 July 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 Manager, Airframe and Structures, 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 establish a comprehensive framework for ensuring the safety and efficiency of civil aviation in Australia. This Act empowers the Governor-General to create regulations aimed at safeguarding air navigation, with the overarching objective of maintaining the highest standards of aviation safety. Within this legislative framework, the Civil Aviation Safety Regulations 1998 were introduced to provide detailed rules and standards for aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives serve as crucial tools for ensuring the continuing airworthiness of aircraft, aligning with Australia's commitments under international conventions such as Annex 8 to the Convention on International Civil Aviation. The policy objective behind these regulations is to mandate that the State of Registry, in this case CASA, enforces continuing airworthiness standards that are consistent with international best practices, thereby protecting public safety in the aviation sector.
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) in Australia, which are crucial for ensuring the safety of air navigation. Under these regulations, the Civil Aviation Safety Authority (CASA) can issue ADs for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments in accordance with the Acts Interpretation Act 1901. ADs are integral to the continuing airworthiness of aircraft as outlined in Annex 8 to the Convention on International Civil Aviation, with the State of Design having the primary responsibility for ensuring airworthiness and the State of Registry implementing these requirements at the aircraft level. CASA, as Australia’s national airworthiness authority, assesses information provided by the State of Design and issues corresponding Australian ADs as needed. This process ensures that safety standards are maintained and that any unsafe conditions identified are addressed effectively. The specific AD/BEECH 90/64, affecting Beechcraft C90 and E90 models, was cancelled by CASA after an assessment determined that the unsafe condition no longer existed, thus no longer necessitating a regulatory requirement.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations for the Act's purposes and in the interest of air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and governed by the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA, as Australia’s national airworthiness authority, to evaluate any ADs issued by the State of Design—the country where the aircraft type was designed. If an AD is issued by the State of Design, CASA must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must also develop or adopt appropriate requirements to ensure the safety of aircraft registered within its jurisdiction.
The issuance of ADs is a crucial mechanism for maintaining airworthiness standards in line with international obligations under Annex 8 to the Convention on International Civil Aviation. For instance, CASA issued AD/BEECH 90/64 for Beechcraft C90 and E90 model aircraft, which was later cancelled due to the resolution of the unsafe condition. This cancellation, effective from 31 July 2008, did not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. The AD cancellation reflects Australia's adherence to international standards and obligations.
Failure to comply with ADs can result in significant legal consequences. Under section 98 of the Civil Aviation Act 1988, non-compliance may be considered an offence, leading to both civil and criminal penalties. The specific penalties can vary, but they may include substantial fines and, in more severe cases, imprisonment. The exact penalties are determined by the severity of the breach and the relevant provisions of the Civil Aviation Act 1988 and other applicable laws. Ensuring compliance with ADs is therefore critical for maintaining aviation safety standards.
