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 issued AD/CESSNA 177/27, affecting Cessna 177 model aircraft in 1980. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 14 February 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 in the Airworthiness Engineering Branch, 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 introduced to ensure the safety and efficiency of civil aviation within Australia. The Act provides the framework under which the Civil Aviation Safety Regulations 1998 were established, and these regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. These ADs are critical in maintaining the continuing airworthiness of aircraft as mandated by international standards such as Annex 8 to the Convention on International Civil Aviation. CASA's role is pivotal in assessing information from the State of Design and issuing corresponding ADs to ensure compliance with safety standards. In the case of AD/CESSNA 177/27, CASA decided to cancel the directive for Cessna 177 model aircraft, effective from 14 February 2008, due to the cessation of the original unsafe condition, without the need for a replacement AD. This cancellation was made under the authority granted by section 84A(2) of the Act and aligns with the policy objective of reducing regulatory burden while maintaining high safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, enable the issuance of airworthiness directives (ADs) which are legislative instruments, designed to ensure the safety of air navigation. These regulations apply to the State of Registry of individual aircraft, mandating their responsibility for the continuing airworthiness of aircraft registered within Australia. The Civil Aviation (Safety) Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which must be assessed and potentially mandated for Australian-registered aircraft. This regulatory framework is established in accordance with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must implement requirements to ensure this airworthiness. The process involves CASA reviewing information from the State of Design and deciding whether to issue an Australian AD to enforce the requirements. For instance, CASA issued and subsequently cancelled AD/CESSNA 177/27 for Cessna 177 model aircraft, reflecting the cessation of the original unsafe condition and reducing regulatory burden. This action was taken without public consultation, as determined by the Office of Best Practice Regulation, which concluded that ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. The issuing of ADs is crucial for maintaining the continuing airworthiness of aircraft, as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design has the responsibility for the type of aircraft and must provide necessary information to the States of Registry.
The obligations under the Civil Aviation Safety Regulations 1998 include ensuring that CASA assesses information from the State of Design and, if appropriate, issues an Australian AD to mandate the requirements for the continuing airworthiness of the aircraft. For instance, CASA issued AD/CESSNA 177/27 in 1980, which affected Cessna 177 model aircraft. Recently, CASA reviewed this AD and decided to cancel it, effective from 14 February 2008, as the original unsafe condition no longer exists. No replacement AD is required. This decision to cancel the AD was made without consulting the Australian public, as it results in a reduction of the regulatory burden, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The cancellation of the AD was authorised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
In terms of consequences for breach, while the specific provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not detail offences and penalties related to non-compliance with ADs, failure to comply with an AD can have serious implications. The Civil Aviation Act 1988 provides for offences and penalties for breaches of aviation safety regulations, which could include fines and imprisonment. Non-compliance with ADs could potentially lead to grounding of aircraft, which in turn could result in significant operational and financial penalties for operators. Furthermore, serious breaches could result in CASA taking enforcement actions, including the suspension or revocation of an aircraft’s certificate of airworthiness.
