CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 US FAA has issued AD 2005-05-15 affecting Honeywell TFE 731 series engines. The US is the State of Design for these engine models. CASA has assessed this AD and has issued Australian AD/TFE 731/33, which will become effective on 4 August 2005.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to establish a regulatory framework governing civil aviation in Australia, ensuring safety and efficiency in the national airspace. This Act empowers the Governor-General to make regulations necessary for the safety of air navigation. One such regulation is the Civil Aviation Safety Regulations 1998, under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for aircraft types and aeronautical products. These directives are legislative instruments issued in accordance with international standards set by the International Civil Aviation Organization (ICAO), ensuring that Australia adheres to global safety protocols. CASA, as the national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, where necessary, issuing corresponding Australian ADs to maintain compliance with international obligations and ensure the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, specifically through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, ensuring compliance with the Act and the safety of air navigation. This legislative framework applies to entities and persons involved in the aviation industry, including aircraft manufacturers, operators, and maintenance providers, within the jurisdiction of Australia. The ADs are mandated to address continuing airworthiness issues, aligning with international standards set by the International Civil Aviation Organization (ICAO). The scope of these directives is national, ensuring that the safety regulations are uniformly applied across all Australian airspace. Notably, ADs are legislative instruments that do not require public consultation or a Regulatory Impact Statement, as they are issued in response to international obligations and directives from the State of Design. The authority to issue these ADs is exercised by CASA, reflecting Australia’s commitment to maintaining international safety standards in civil aviation.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as implemented through the Civil Aviation Safety Regulations 1998, pertain to the issuance and enforcement of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations for the safety of air navigation, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for certain types of aircraft or aeronautical products. This regulatory framework is designed to ensure that all aircraft operating in Australian airspace meet specific safety standards. Section 39.001(5) further clarifies that ADs are disallowable instruments, subject to the legislative scrutiny required by section 46A of the Acts Interpretation Act 1901, and thus are considered legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions primarily concern CASA and the States of Design and Registry. CASA, as Australia’s national airworthiness authority, must evaluate any AD issued by a State of Design that pertains to aircraft registered in Australia. If deemed necessary, CASA must issue a corresponding Australian AD to enforce the requirements established by the State of Design. The States of Design, such as the United States for the Honeywell TFE 731 series engines, are responsible for ensuring the continuing airworthiness of aircraft types they design and must provide any necessary information to States of Registry, including Australia. States of Registry, such as Australia, are obligated to develop or adopt requirements that ensure the continuing airworthiness of aircraft registered within their jurisdiction, thereby ensuring compliance with international safety standards.
Failure to comply with the provisions of ADs can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to enforcement actions by CASA, which may include fines, suspension or revocation of aircraft certificates, or other regulatory sanctions. Additionally, any breaches of safety regulations may result in civil or criminal penalties, depending on the severity and intent of the violation. The specific penalties for breaches of ADs are not detailed in the provided text, but generally, such violations can attract substantial financial penalties and, in serious cases, criminal charges. The regulatory framework ensures that all stakeholders, including aircraft operators and manufacturers, are held accountable for maintaining the airworthiness of aircraft in accordance with the prescribed safety standards.
