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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 400/7 affecting Cessna 401 and 402 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 28 August 2008. No replacement AD is required.
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, Systems and New Technologies 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 address the need for comprehensive regulation of civil aviation within Australia, ensuring safety and efficiency in air navigation. This Act provides the legislative foundation for the Civil Aviation Safety Regulations 1998, which were established to further refine and operationalise the provisions of the Act. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. These directives are a crucial mechanism in ensuring that aircraft meet safety standards as required under the Convention on International Civil Aviation. The Act allows CASA to cancel ADs, as demonstrated in the case of AD/CESSNA 400/7, which has been cancelled due to Australia’s obligations under the Convention, and for which no replacement directive is needed. The cancellation of this AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the legislative framework provided by the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, as outlined in subregulation 39.001(5) and the Acts Interpretation Act 1901, with the authority to enforce safety measures mandated by the Civil Aviation Act 1988. The ADs are intended to ensure the continuing airworthiness of aircraft and aeronautical products, a responsibility that primarily lies with the State of Registry as per Annex 8 to the Convention on International Civil Aviation. Given Australia's obligations under this international convention, CASA issues these directives to maintain safety standards, although specific public consultations are not required for ADs. The recent cancellation of AD/CESSNA 400/7, which affected Cessna 401 and 402 model aircraft, exemplifies CASA's role in responding to international safety directives and underscores the need for continuous compliance with global aviation standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 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 essential for maintaining the safety and airworthiness of aircraft in Australia, and they are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs are issued in line with the broader safety objectives set forth in the Civil Aviation Act 1988. Regulation 39.001(5) further clarifies that ADs are disallowable instruments, aligning with section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations are significant. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to the States of Registry to ensure that individual aircraft maintain their airworthiness. Meanwhile, the State of Registry must develop or adopt specific requirements to guarantee the airworthiness of aircraft within its jurisdiction. CASA, acting on behalf of Australia, has issued, reviewed, and subsequently cancelled an AD affecting Cessna 401 and 402 model aircraft. This action was taken in accordance with Australia’s international obligations and reflects the dynamic nature of airworthiness management.
Breaching the requirements set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in serious consequences. While specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with ADs could lead to significant safety risks. Given the critical nature of airworthiness directives, any failure to adhere to these regulations could result in severe civil or criminal penalties, depending on the extent of the breach and its impact on aviation safety. The authorities have the power to enforce compliance rigorously to uphold the highest standards of aviation safety.
