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/BEECH 55/22, affecting Beech 55 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago, and ongoing maintenance actions are contained in AD/BEECH 55/82.
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 was enacted to regulate civil aviation in Australia, ensuring safety and efficiency in air navigation. As part of its mandate, the Act empowers the Governor-General to make regulations, including the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products. These ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988 thus addresses the need for stringent safety regulations in civil aviation, ensuring that all aircraft meet necessary standards to maintain airworthiness. CASA, acting on behalf of the Australian government, is responsible for enforcing these regulations and issuing directives as required to maintain the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations that promote the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments subject to disallowance and scrutiny under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft, aligning with the international standards set out in Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry both play pivotal roles in this regulatory framework, with CASA acting as Australia's national airworthiness authority, responsible for issuing Australian ADs when necessary. The AD/BEECH 55/22, affecting Beech 55 model aircraft from 1971, is one such directive that CASA has reviewed and decided to cancel, effective from 5 June 2008, due to the completion of necessary inspections and modifications on affected aircraft, with ongoing maintenance actions outlined in another directive, AD/BEECH 55/82.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are instrumental in ensuring the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The ADs serve as a crucial form of continuing airworthiness information, issued by most ICAO Contracting States, including Australia. For instance, CASA issued AD/BEECH 55/22 in 1971, which affected Beech 55 model aircraft, but has since decided to cancel this directive, effective from 5 June 2008. This cancellation results from the aircraft having undergone necessary inspections and modifications long ago, with ongoing maintenance actions already covered by another AD, AD/BEECH 55/82.
Under the Civil Aviation Act 1988, the State of Registry is responsible for the continuing airworthiness of individual aircraft. This responsibility includes developing or adopting requirements to ensure the airworthiness of aircraft registered within their jurisdiction. CASA, acting on behalf of Australia, must assess any airworthiness directives issued by the State of Design and, if appropriate, issue corresponding Australian ADs to enforce the necessary requirements. This ensures that Australian-registered aircraft comply with international safety standards.
CASA, as the national airworthiness authority, must ensure that any airworthiness directives issued by the State of Design are assessed and, if necessary, translated into Australian legislation. This process involves careful consideration and evaluation of the information provided by the State of Design to maintain the safety standards required for Australian-registered aircraft. The issuance of an AD is a legislative instrument, as stipulated by subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and is subject to disallowance under section 46A of the Acts Interpretation Act 1901.
Failure to comply with airworthiness directives can result in significant legal consequences. Offences under the Civil Aviation Act 1988 may lead to substantial penalties, with the exact amount depending on the nature and severity of the breach. Civil penalties can include fines, while criminal penalties may result in imprisonment. The specific penalties are outlined in the Act and are enforced to ensure adherence to the safety regulations governing air navigation in Australia. The rigorous oversight and enforcement of these directives are critical to maintaining the high safety standards required in civil aviation.
