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 369/26 affecting McDonnell Douglas (Hughes) 369 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 369/26. 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 regulate civil aviation in Australia, focusing on the safety and efficiency of air navigation. It grants the Governor-General the authority to make regulations under section 98, ensuring the safety of air navigation and delegating the Civil Aviation Safety Authority (CASA) the power to issue airworthiness directives (ADs) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs are legislative instruments subject to disallowance and are essential for maintaining the continuing airworthiness of aircraft in accordance with Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that Australia adheres to international standards while maintaining stringent safety protocols for its domestic aviation sector.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These directives are essential tools under Annex 8 to the Convention on International Civil Aviation, which places the responsibility of ensuring an aircraft's continuing airworthiness on the State of Design and the State of Registry. In Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design for aircraft on the Australian Register and, if appropriate, issue corresponding Australian ADs. The recent cancellation of AD/HU 369/26, which affected McDonnell Douglas (Hughes) 369 series helicopters, demonstrates CASA's commitment to safety, as the unsafe condition identified by the directive no longer exists, rendering a replacement AD unnecessary. This legislative process is governed by the authority of the Manager Systems and New Technologies in the Airworthiness Engineering Group, operating under subsection 84A(2) of the Civil Aviation Act 1988, and the AD is classified as a disallowable instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are intended to ensure the continuing safety and airworthiness of aircraft, as mandated by section 98 of the Civil Aviation Act 1988. Each AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is recognised as a legislative instrument pursuant to section 6 of the Legislative Instruments Act 2003.
The obligations imposed on the parties governed by these regulations are significant. CASA, as Australia's national airworthiness authority, must carefully assess any airworthiness directives issued by the State of Design and determine whether an Australian AD is necessary to ensure the continuing airworthiness of aircraft registered in Australia. This process is vital to fulfil Australia's responsibilities under Annex 8 to the Convention on International Civil Aviation, where the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft.
The obligations extend to ensuring that when a State of Design issues an AD, CASA must evaluate and, if necessary, issue a corresponding Australian AD to enforce the safety requirements. This ensures that all aircraft operating under Australian registration meet the required safety standards. The AD/HU 369/26, which affected McDonnell Douglas (Hughes) 369 series Helicopters, was assessed and subsequently cancelled by CASA because the unsafe condition it addressed no longer existed, illustrating the regulatory process in action.
In terms of consequences for breach, the regulations do not explicitly state penalties for non-compliance with ADs. However, failure to adhere to airworthiness directives can lead to serious safety issues, potentially resulting in civil or criminal liability for aircraft operators and manufacturers. The severity of the consequences can include significant fines, imprisonment, or both, depending on the nature and extent of the non-compliance and its impact on aviation safety. The exact penalties are determined by relevant aviation safety legislation and civil or criminal law, where the breach may also be considered a violation of safety regulations.
