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 55/2, affecting Beech 55 model aircraft in 1961. 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.
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 and ensure the safety of air navigation. In line with this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 respectively. In accordance with international standards, the State of Design is responsible for the continuing airworthiness of an aircraft type, and CASA must assess and implement relevant ADs for aircraft registered in Australia. CASA has determined that AD/BEECH 55/2, which affects Beech 55 model aircraft from 1961, is to be cancelled as of 5 June 2008, following a review that found no further action is necessary for the affected aircraft. The decision to cancel this AD, which reduces the regulatory burden, has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. Regulation 39.001 allows CASA to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments and subject to disallowance under the Acts Interpretation Act 1901. The ADs serve to implement continuing airworthiness requirements as mandated by the International Civil Aviation Organization (ICAO) under Annex 8. The State of Registry, in this case CASA, is responsible for ensuring the continuing airworthiness of aircraft registered in Australia. The issuance of ADs is a common practice among ICAO Contracting States, ensuring harmonised safety standards. CASA issued AD/BEECH 55/2 for Beech 55 model aircraft in 1961, which has now been cancelled effective from 5 June 2008, as the affected aircraft have already been inspected and modified as necessary. This cancellation, which reduces the regulatory burden, did not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations for air navigation safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft types or aeronautical products. These ADs are critical for ensuring the ongoing airworthiness of aircraft, aligning with the State of Design's responsibility under Annex 8 to the Convention on International Civil Aviation. Each AD is a disallowable instrument under the Acts Interpretation Act 1901, meaning they must comply with specific legislative processes as outlined in the Legislative Instruments Act 2003. For instance, CASA issued AD/BEECH 55/2 in 1961 for Beech 55 model aircraft, which has now been cancelled effective from 5 June 2008. This cancellation was made after thorough review and is deemed appropriate as all affected aircraft have already undergone necessary inspections and modifications.
The obligations under this legislation require the State of Design to provide necessary information to ensure the continuing airworthiness of an aircraft type. In turn, the State of Registry must implement these directives to maintain the airworthiness of individual aircraft registered within its jurisdiction. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and issue corresponding Australian ADs where necessary. This dual responsibility ensures that both design and registry states are actively involved in maintaining safety standards. The State of Design's issuance of an AD triggers a process where CASA evaluates and, if appropriate, issues a corresponding AD to mandate the required safety measures. This regulatory framework is designed to ensure that all aircraft remain airworthy and comply with international safety standards.
Failure to comply with airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to significant penalties. These can include substantial fines or imprisonment, depending on the severity of the breach. The maximum penalties are not explicitly stated in the provided text, but they generally reflect the seriousness of compromising aviation safety. Additionally, non-compliance can result in the grounding of affected aircraft, further emphasizing the importance of adhering to the directives. The regulatory framework is designed to deter any actions that might compromise the safety of air navigation, thereby protecting the public and maintaining the integrity of the aviation industry.
CASA's role in issuing and cancelling ADs is crucial to maintaining these safety standards. The process is overseen by the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with subsection 84A(2) of the Act. This ensures that any decisions made are in line with the legislative requirements and safety objectives. The cancellation of AD/BEECH 55/2, for example, demonstrates CASA's commitment to reducing unnecessary regulatory burdens while maintaining safety. The decision to cancel the AD without public consultation was deemed appropriate given that all necessary safety measures had already been implemented. This reflects CASA's efficiency in managing airworthiness directives and ensuring that the regulatory framework remains effective and responsive to safety needs.
