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/MCH/1 affecting Aero Resources J2 series gyroplanes in 1973. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
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, among other purposes. In line with this, the Civil Aviation Safety Regulations 1998 were established to provide detailed rules for the implementation of the Act. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments and must be assessed and potentially adopted by the State of Registry for individual aircraft to ensure their continuing airworthiness. CASA issued AD/MCH/1 in 1973 for Aero Resources J2 series gyroplanes, but has decided to cancel this directive, effective 17 January 2008, due to it no longer being necessary as the unsafe condition it addressed is now covered by another directive. No public consultation was required for this cancellation as it reduces the regulatory burden, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. This AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, under the authority granted by the Act.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of airworthiness directives (ADs) in Australia. This Act applies to the issuance and enforcement of ADs to ensure the safety of air navigation. It primarily governs the actions of the Civil Aviation Safety Authority (CASA), which acts as Australia's national airworthiness authority. CASA has the authority to issue ADs for specific kinds of aircraft or aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The scope of the Act encompasses all aircraft registered within Australia, and it mandates that the State of Registry, in this case CASA, ensures the continuing airworthiness of these aircraft. This responsibility includes adopting or developing requirements for airworthiness as necessary. The geographic reach of the Act is national, applying to all aircraft within Australia's jurisdiction, and it aligns with international standards set by the International Civil Aviation Organization (ICAO). Exemptions or thresholds for the application of ADs are not specified in this particular regulatory action, but typically, ADs are issued based on identified safety concerns and the necessity to mandate specific actions or modifications to aircraft.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations aimed at enhancing the safety of air navigation, while the Civil Aviation Safety Regulations 1998 (regulation 39.001) authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and are legislative instruments as per the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation stipulates that the State of Design is responsible for the ongoing airworthiness of an aircraft type and must furnish necessary information to ensure this to the States of Registry. The State of Registry, in turn, is accountable for the continuing airworthiness of individual aircraft, developing or adopting requisite requirements to maintain this.
Entities governed by the Act and its regulations are mandated to adhere to the ADs issued by CASA. This involves implementing any modifications or procedures outlined in the ADs to ensure the aircraft remain airworthy. These directives may include mandatory inspections, repairs, or modifications to aircraft components, systems, or procedures. Compliance with these directives is essential for maintaining the safety standards set forth by the Civil Aviation Act and the Civil Aviation Safety Regulations. Failure to comply with an AD can result in severe consequences, including the potential grounding of aircraft and legal ramifications.
The Act imposes various obligations on entities such as aircraft operators and manufacturers. These include the duty to ensure that their aircraft meet the specified airworthiness standards and to promptly implement any ADs issued by CASA. Aircraft operators must also ensure that their pilots and maintenance personnel are adequately trained and informed about the requirements of any ADs relevant to their aircraft. This ensures that all safety measures are effectively communicated and adhered to. Furthermore, manufacturers must provide detailed information about any design changes or issues that may affect the airworthiness of their products, facilitating timely and effective regulatory responses.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline specific offences and penalties for non-compliance with ADs. Violating an AD can lead to significant civil penalties, including fines, as well as criminal charges. The maximum penalties for breaches of these regulations can include substantial fines and imprisonment, depending on the severity of the offence. For example, under section 225 of the Act, individuals and corporations can be fined up to $210,000 for serious breaches, while section 226 imposes additional fines and imprisonment terms for ongoing non-compliance. These stringent penalties underscore the importance of adhering to airworthiness directives to ensure the safety and integrity of the aviation industry.
