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/HU 369/40 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/40. The cancellation will become effective on 4 June 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 Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive regulatory framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This Act provides the authority for the issuance of airworthiness directives, which are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products. Under the authority granted by the Act, the Civil Aviation Safety Regulations 1998 were also introduced, specifically detailing the processes and requirements for issuing airworthiness directives. The Civil Aviation Safety Authority (CASA) has the power to issue these directives, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The objective of these directives is to comply with international standards, particularly those set out in Annex 8 of the Convention on International Civil Aviation, ensuring that the State of Design and the State of Registry both fulfil their respective responsibilities for the airworthiness of aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified kinds of aircraft or aeronautical products, with these ADs being legislative instruments subject to disallowance as per section 46A of the Acts Interpretation Act 1901. This regulatory framework is integral to ensuring the safety of air navigation and aligns with the obligations under Annex 8 of the Convention on International Civil Aviation, where the State of Design is tasked with the responsibility of continuing airworthiness for an aircraft type. For aircraft on the Australian Register, CASA, acting as the national airworthiness authority, must evaluate and, if necessary, issue Australian ADs to enforce the requirements set by the State of Design. The process involves a cancellation of the Australian AD/HU 369/40 for McDonnell Douglas (Hughes) 369 series Helicopters, effective from 4 June 2009, due to the elimination of the previously identified unsafe condition, thereby obviating the need for a replacement AD. This legislative action is conducted without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The issuance and cancellation of ADs are carried out by CASA, specifically by the Manager Systems and New Technologies within the Airworthiness Engineering Group, in compliance with subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, particularly in conjunction with the Civil Aviation Safety Regulations 1998, outlines the framework for the issuance and management of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory power is further clarified under subregulation 39.001(5), which designates ADs as disallowable instruments under the Acts Interpretation Act 1901, and thus as legislative instruments under the Legislative Instruments Act 2003.
These ADs serve a critical role in maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design is primarily responsible for ensuring the airworthiness of aircraft types and must provide necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. In the context of Australia, CASA, as the national airworthiness authority, is responsible for assessing and issuing Australian ADs that reflect the requirements of the State of Design for aircraft registered in Australia.
In the specific instance of AD/HU 369/40 affecting McDonnell Douglas (Hughes) 369 series Helicopters, CASA has assessed the original AD and determined that it should be cancelled. This decision was made due to the resolution of the unsafe condition that initially prompted the AD, and thus no replacement AD is required. The cancellation of this AD took effect on 4 June 2009, aligning with Australia's obligations under the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to act promptly and decisively when unsafe conditions are identified. CASA must assess the information provided by the State of Design and issue an Australian AD if necessary. This ensures that the safety standards required by the Convention are met. Additionally, the legislative framework mandates that ADs are managed as legislative instruments, subject to specific regulatory oversight and disallowance provisions.
Failure to comply with the provisions of the Act or the Regulations, including the issuance of ADs, may result in significant consequences. The Act and Regulations provide for both civil and criminal penalties for non-compliance. Civil penalties can include fines and other financial penalties, while criminal penalties may include imprisonment and/or substantial fines. The maximum penalties depend on the specific breach and the severity of the non-compliance, with the potential for significant financial and reputational damage to those found in breach.
