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.
Transport Canada has issued AD CF-2007-21 affecting Bell 407 series helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 407/30 which will become effective on 14 September 2007.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, aims to ensure the safety of air navigation and was introduced to address the need for regulations governing the safety of civil aviation in Australia. Section 98 of the Act empowers the Governor-General to make regulations in the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, including the issuance of airworthiness directives (ADs) under regulation 39.001, with subregulation 39.001(5) classifying ADs as disallowable instruments. The Civil Aviation Safety Authority (CASA) is responsible for issuing these directives, which are integral to maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 of the Convention on International Civil Aviation. This legislative framework ensures that Australia aligns with international standards and obligations, facilitating the safety and regulation of civil aviation within the country.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation in Australia, and includes provisions for the issuance of airworthiness directives (ADs). Under this Act, the Civil Aviation Safety Authority (CASA) can issue ADs for certain kinds of aircraft or aeronautical products. These ADs are considered legislative instruments and are designed to ensure the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation. The State of Design of an aircraft type holds primary responsibility for its airworthiness, while the State of Registry, in this case CASA, must ensure the aircraft meets the required safety standards. ADs are issued to mandate specific safety requirements for aircraft types registered in Australia, and they often respond to similar directives issued by the aircraft's State of Design. For example, following the issuance of an AD by Transport Canada for Bell 407 series helicopters, CASA issued its own corresponding AD, which became effective on 14 September 2007. The process for issuing such ADs does not require public consultation or a Regulatory Impact Statement, as it is grounded in international obligations and the specific safety needs of the aircraft in question.
Key Provisions
The Civil Aviation Act 1988, under section 98, allows the Governor-General to create regulations that are essential for the safety of air navigation. One of these regulations, as outlined in section 39.001 of the Civil Aviation Safety Regulations 1998, enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). An AD, as defined in subregulation 39.001(5), is a disallowable instrument as per section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs play a critical role in maintaining the safety and airworthiness of aircraft.
These airworthiness directives impose certain obligations on the parties and entities they govern. Firstly, the State of Design, which is the state where the aircraft type was designed, must ensure the continuing airworthiness of the aircraft type and provide necessary information to the States of Registry. The State of Registry, which is responsible for the individual aircraft’s continuing airworthiness, must develop or adopt requirements to ensure the aircraft's airworthiness. CASA, as Australia's national airworthiness authority, must assess the information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that Australian registered aircraft comply with international safety standards.
In terms of compliance and enforcement, breaching the requirements of an AD can have serious consequences. Offences related to non-compliance with ADs may result in both civil and criminal penalties. The exact nature and severity of these penalties can vary, but the Civil Aviation Act 1988 and associated regulations provide for significant penalties for non-compliance. For instance, failure to comply with an AD could result in fines and, in severe cases, criminal charges. The specific penalties are not detailed in the provided text but are outlined in the broader legislative framework and can be substantial, reflecting the importance of adhering to airworthiness directives for safety reasons.
Given the global nature of aviation, ADs are often issued in response to international agreements and standards, such as those set out in Annex 8 to the Convention on International Civil Aviation. This international cooperation ensures that safety standards are uniformly applied across borders, which is crucial for maintaining the safety of air navigation worldwide. The issuance of an AD, such as the one affecting Bell 407 series helicopters, is a direct result of Australia's obligations under these international agreements, underscoring the interconnected nature of aviation safety regulations.
