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/JT15D/2 affecting Pratt and Whitney Canada JT15D series turbine engines. CASA has assessed this AD and as a result has cancelled Australian AD/JT15D/2. The cancellation will become effective on 27 August 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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to ensure the safety and efficiency of civil aviation in Australia, providing a framework for the regulation of aviation safety and air navigation. In alignment with this objective, the Civil Aviation Safety Regulations 1998 were introduced to further detail the requirements and procedures for maintaining the airworthiness of aircraft and aeronautical products. Under section 98 of the Act, the Governor-General is empowered to make regulations for air navigation safety, with regulation 39.001 authorising the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft types or aeronautical products. These ADs serve as a critical tool for ensuring the continuing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. CASA’s role includes assessing ADs issued by the State of Design and, if necessary, issuing corresponding Australian ADs to enforce the required safety measures. The issuance and cancellation of such directives are integral to maintaining safety standards and aligning with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, in line with the overarching Civil Aviation Act 1988. These ADs are legislative instruments that serve to ensure the continuing airworthiness of aircraft registered in Australia, aligning with international standards under Annex 8 of the Convention on International Civil Aviation. This regulatory framework applies to entities such as aircraft manufacturers, operators, and maintenance providers who must comply with the ADs to ensure safety in air navigation. The geographic scope of these regulations is national, extending across Australia, and they do not require consultation with the public or a Regulatory Impact Statement as they pertain to specific technical safety requirements rather than broader policy changes. Additionally, CASA has the authority to cancel ADs, as demonstrated by the recent cancellation of AD/JT15D/2 concerning Pratt and Whitney Canada JT15D series turbine engines, which will take effect from 27 August 2009, indicating that the unsafe condition previously identified no longer exists.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation. Under section 98 of the Act, the Governor-General has the power to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and are classified as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are significant. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry to ensure the aircraft's ongoing airworthiness. The State of Registry, in this case, CASA, must then assess this information and, if appropriate, issue an Australian AD to enforce the requirements stipulated by the State of Design. For example, CASA assessed and subsequently cancelled Australian AD/JT15D/2 for Pratt and Whitney Canada JT15D series turbine engines due to the unsafe condition no longer existing.
Failure to comply with the requirements set forth by these regulations can result in serious consequences. The Civil Aviation Act 1988 outlines various offences and penalties for non-compliance, although the specific details of these penalties are not provided in the text. In general, breaches of airworthiness regulations can lead to both civil and criminal penalties, depending on the severity and intent of the violation. The maximum penalties for such breaches can include substantial fines and, in some cases, imprisonment.
Given that ADs are integral to the continuing airworthiness of aircraft, any failure to adhere to these directives can compromise flight safety. CASA’s role in issuing and enforcing these directives is crucial in maintaining high safety standards in the aviation industry.
