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-2008-05 affecting Bombardier DHC-8 series aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/141, which will become effective on 10 April 2008.
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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legal framework governing civil aviation in Australia, addressing various aspects of air navigation, aircraft registration, and safety standards. The Act empowers the Governor-General to make regulations for the safety of air navigation, with specific reference to the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments designed to ensure the continuing airworthiness of aircraft, in line with Australia's obligations under the Convention on International Civil Aviation. The policy objective is to harmonise Australian aviation safety standards with international practices, ensuring the safety and reliability of aircraft operating within Australian airspace. As such, when a State of Design issues an AD, the Civil Aviation Safety Authority (CASA) must assess and, if necessary, issue a corresponding Australian AD to mandate the requirements for aircraft on the Australian Register.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). These regulations apply to all aircraft registered in Australia, ensuring compliance with international safety standards as set out by the Convention on International Civil Aviation. ADs are legislative instruments made under the authority of CASA to mandate safety requirements for specific types of aircraft or aeronautical products. They are issued in response to safety concerns identified by the State of Design, which is responsible for the continuing airworthiness of the aircraft type. The State of Registry, which in the case of Australia is CASA, is then required to assess and, if necessary, adopt these directives to ensure compliance with Australian regulations. Notably, ADs do not undergo public consultation or require a Regulatory Impact Statement, as they are issued under Australia's international obligations and in direct response to directives from the State of Design.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products (section 98 and regulation 39.001). An AD is a legislative instrument that can be issued to mandate safety requirements for specific types of aircraft (subsection 39.001(5)). These directives are instrumental in maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the obligations on CASA include the assessment and, if necessary, the issuance of ADs in response to information from the State of Design or based on safety concerns identified by CASA itself. CASA's role is to ensure that any AD issued complies with Australia's obligations under international conventions and national safety regulations. The State of Registry, which in the Australian context is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia. This includes evaluating foreign ADs and deciding whether they should be adopted or adapted for Australian conditions.
Failure to comply with an AD can result in severe consequences. Under the Civil Aviation Act 1988, an aircraft that does not comply with an AD can be deemed unairworthy, which means it cannot legally be operated until the required modifications or inspections are completed. Additionally, CASA has the authority to take enforcement actions against operators who fail to comply with ADs. These actions can include fines, suspension or revocation of airworthiness certificates, and other regulatory sanctions. The exact penalties depend on the severity of the non-compliance and can include significant financial penalties as well as potential criminal charges for serious safety violations.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the process and obligations for issuing and complying with ADs, ensuring that all aircraft meet stringent safety standards. CASA, as the national airworthiness authority, has the responsibility to issue these directives and enforce compliance, thereby maintaining the high safety standards required in civil aviation.
