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.
The Civil Aviation Safety Authority or its predecessors issued AD/HILLER 12/38 affecting Hiller UH-12 series helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HILLER 12/38. The cancellation will become effective on 27 August 2009. No replacement AD is required, as the unsafe condition no longer exists.
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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, 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, particularly focusing on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations under section 98, which are intended to enhance the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance and are designed to maintain the continuing airworthiness of aircraft in line with international standards as set out in Annex 8 to the Convention on International Civil Aviation. The enactment of this legislation aimed to address gaps in aircraft safety regulations by ensuring compliance with international safety standards and fostering cooperation between States of Design and States of Registry to maintain the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, outlines the regulatory framework governing airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products, which are critical in maintaining the continuing airworthiness of aircraft registered in Australia. These ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are issued in accordance with Annex 8 of the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of aircraft types on the State of Design, while the State of Registry is tasked with implementing the necessary requirements. In the specific case of AD/HILLER 12/38, CASA assessed the AD issued by the State of Design and subsequently cancelled it due to the resolution of the unsafe condition, effective from 27 August 2009, without the need for a replacement AD. The cancellation process aligns with Australia’s international obligations and did not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to make regulations to ensure the safety of air navigation, and under section 98, regulation 39.001 of the Civil Aviation Safety Regulations 1998 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs can apply to specific types of aircraft or aeronautical products. Subregulation 39.001(5) stipulates that an AD is a disallowable instrument, and thus a legislative instrument under the Legislative Instruments Act 2003. This regulatory framework ensures that the State of Design holds the primary responsibility for the continuing airworthiness of aircraft types, while the State of Registry is tasked with ensuring the airworthiness of individual aircraft. When a State of Design issues an AD, CASA must review this information and, if necessary, issue an Australian AD to enforce the requirements. This process ensures that safety standards are consistently maintained and that any unsafe conditions are promptly addressed.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include ensuring that the State of Design provides all necessary information to maintain the airworthiness of aircraft types. The State of Registry is responsible for developing or adopting requirements to guarantee the continuing airworthiness of aircraft within its jurisdiction. CASA must assess any ADs issued by a State of Design and decide whether to issue an Australian AD. This involves a thorough review to determine the applicability and necessity of the AD in the Australian context. Additionally, the regulations require CASA to communicate any changes or cancellations of ADs effectively, ensuring that all relevant stakeholders are informed of the updated safety requirements or the resolution of safety concerns.
Under the Civil Aviation Safety Regulations 1998, any breach of the airworthiness requirements specified in an AD can lead to severe consequences. Non-compliance may result in civil penalties, including fines up to the maximum allowable by law. Additionally, the operation of an aircraft that does not meet the AD requirements can be considered a violation of airworthiness standards, potentially leading to the grounding of the aircraft. In more serious cases, non-compliance could result in criminal charges, with penalties that may include imprisonment. The severity of these penalties underscores the importance of adhering to airworthiness directives to maintain the safety of air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for ensuring the safety and airworthiness of aircraft. The issuance and enforcement of airworthiness directives are critical components of this framework, with specific obligations on both the State of Design and the State of Registry. Failure to comply with these regulations can result in significant civil and criminal penalties, reflecting the high priority placed on aviation safety.
