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 United States FAA issued Emergency AD 2008-18-52 affecting MD Helicopters MD 500 and MD 600 series helicopters. The United States is the State of Design for these helicopters. As a result CASA has amended the equivalent Australian AD to AD/HU369/121 Amendment 1. The amended AD, AD/HU369/121 Amendment 1, will become effective on 28 August 2008. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review 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 provide a legislative framework for the regulation of civil aviation in Australia, with a focus on ensuring the safety of air navigation. In line with this objective, the Governor-General has the authority under section 98 of the Act to make regulations necessary for the interests of safety, including the issuance of airworthiness directives (ADs) as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments subject to disallowance and are integral to maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) acts as Australia’s national airworthiness authority, responsible for issuing Australian ADs in response to directives from the State of Design, thereby ensuring compliance with international standards and obligations. The process of issuing such directives, such as the recent amendment to AD/HU369/121 Amendment 1 in response to the United States FAA’s Emergency AD 2008-18-52, is carried out by CASA without public consultation due to its alignment with international obligations and the nature of the regulatory requirements.
Scope and Application
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Act applies to any person or entity involved in civil aviation activities within Australia, including aircraft operators, manufacturers, and maintenance providers. The scope of the ADs extends to all aircraft and aeronautical products registered in Australia, ensuring that they meet the necessary safety standards as determined by CASA. Geographically, the Act's provisions apply nationally across Australia, encompassing all states and territories. While the Act generally applies to all relevant aviation activities, specific exclusions and exemptions may be outlined in subordinate regulations or other legislative instruments. Furthermore, the Act mandates that CASA, as Australia's national airworthiness authority, must issue ADs in response to directives from the State of Design, ensuring that Australia fulfils its obligations under the Convention on International Civil Aviation. These ADs are legislative instruments, subject to disallowance, and are created without the requirement for public consultation or a Regulatory Impact Statement, given their urgent and safety-focused nature.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations that support the Act and enhance the safety of air navigation. This regulatory framework ensures that ADs, which are legislative instruments under the Legislative Instruments Act 2003, are a critical tool for maintaining the continuing airworthiness of aircraft. Under the Convention on International Civil Aviation, the State of Design has the primary responsibility for ensuring the airworthiness of an aircraft type, while the State of Registry, such as CASA in Australia, is tasked with ensuring the airworthiness of individual aircraft registered within its jurisdiction.
The obligations placed on parties governed by this Act include the necessity for the State of Design to provide essential information to ensure the continuing airworthiness of an aircraft type. For example, when the United States FAA issued Emergency AD 2008-18-52 affecting MD Helicopters MD 500 and MD 600 series helicopters, Australia, as the State of Registry, was required to assess this information and issue a corresponding Australian AD. CASA issued AD/HU369/121 Amendment 1 to align with the US directive, ensuring that Australian-registered helicopters meet the same safety standards. This process underscores the importance of international cooperation and adherence to the Convention on International Civil Aviation.
Failing to comply with airworthiness directives can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to both civil and criminal penalties. For instance, operating an aircraft that does not meet the requirements of an AD can result in civil penalties, including fines and potential revocation of the aircraft’s certificate of airworthiness. Additionally, individuals or companies found in violation of an AD may face criminal charges, which could result in substantial fines and imprisonment. The severity of these penalties highlights the importance of adhering to the directives issued by CASA and the necessity for compliance with international safety standards.
