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 33/21 Amdt 1, affecting Beech 33 and 35-33 model aircraft in 1975. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
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 establish and regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation. One of the key provisions of this Act is the ability of the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation, as outlined in section 98. The Civil Aviation Safety Regulations 1998, in turn, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, as stipulated in regulation 39.001. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, and they play a critical role in maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation.
In this context, CASA issued AD/BEECH 33/21 Amdt 1 in 1975, which affected Beech 33 and 35-33 model aircraft. After a thorough review, CASA has decided to cancel this AD, effective 10 April 2008, as the original unsafe condition no longer exists, thereby reducing the regulatory burden. This decision was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Notably, no consultation with the Australian public was necessary, as the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, as augmented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) to mandate safety measures for specific types of aircraft or aeronautical products. These directives are legislative instruments that come into effect following the provisions set out in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The issuance of ADs aligns with international standards, particularly those stipulated by Annex 8 to the Convention on International Civil Aviation, where the State of Design is tasked with ensuring the continuing airworthiness of an aircraft type. CASA, acting as the national airworthiness authority, must evaluate and, if necessary, issue Australian ADs to enforce the requirements of the State of Design on aircraft registered in Australia. This comprehensive approach ensures that Australian aviation standards are both nationally and internationally compliant.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety and airworthiness of aircraft in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and must be assessed and possibly adopted by Australia as per Annex 8 of the Convention on International Civil Aviation.
Under these provisions, CASA is responsible for issuing ADs to ensure the continuing airworthiness of aircraft registered in Australia. This involves reviewing any ADs issued by the State of Design and determining if they should be implemented in Australia. For example, CASA issued AD/BEECH 33/21 Amdt 1 in 1975 for Beech 33 and 35-33 model aircraft. After a review, CASA decided to cancel this AD effective 10 April 2008, as the unsafe condition it addressed no longer exists, thereby reducing the regulatory burden.
The obligations on CASA include assessing any ADs from the State of Design, issuing appropriate ADs for Australian-registered aircraft, and ensuring compliance with international standards. CASA must also cancel ADs when the conditions they address no longer apply, such as with AD/BEECH 33/23 Amdt 1. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, and no public consultation was necessary for this cancellation.
Failure to comply with ADs can result in serious consequences. Under section 84A(2) of the Civil Aviation Act 1988, CASA can enforce compliance and take action against non-compliance. Penalties for non-compliance can include fines and imprisonment, with the specific penalties depending on the severity of the breach. The issuance and enforcement of ADs are critical to maintaining the high safety standards required in civil aviation.
