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 US FAA has issued AD 71-07-01 affecting JT-8D model aircraft engines. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/JT8D/43, which will become effective on 19 November 2009.
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 Initial Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to regulate and ensure the safety of air navigation in Australia. As a foundational piece of legislation, it empowers the Governor-General to create regulations aimed at maintaining the safety of air navigation. One such regulation, specified in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, considered legislative instruments under the Legislative Instruments Act 2003, are critical for ensuring the continuing airworthiness of aircraft and aeronautical products. This legislative framework ensures that Australia adheres to international standards set by the Convention on International Civil Aviation, specifically Annex 8, which mandates that the State of Design must provide necessary information to ensure an aircraft's continuing airworthiness. CASA, as Australia’s national airworthiness authority, assesses this information and, if necessary, issues corresponding Australian ADs to enforce the requirements set by the State of Design.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, pursuant to the Civil Aviation Act 1988, establish the framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, thereby mandating compliance with airworthiness standards. Such directives are considered legislative instruments under the Legislative Instruments Act 2003 and are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which assigns responsibility for continuing airworthiness to the State of Design. For aircraft registered in Australia, CASA, acting as the national airworthiness authority, must assess and, if necessary, issue corresponding Australian ADs to enforce the requirements set by the State of Design. This process ensures that Australian registered aircraft meet international safety standards, although public consultation or Regulatory Impact Statements are not required as these directives are issued in response to international obligations and pre-existing State of Design directives.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to make 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) has the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products (sections 98 and 39.001). These ADs are legislative instruments, as outlined in section 46A of the Acts Interpretation Act 1901 and further clarified in section 6 of the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, a responsibility that ultimately lies with the State of Design, which must provide necessary information to the States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations require CASA to assess any ADs issued by the State of Design for types of aircraft registered in Australia. If deemed appropriate, CASA must then issue an Australian AD to ensure that the requirements of the original directive are met within the Australian aviation context. For example, following the issuance of AD 71-07-01 by the US Federal Aviation Administration (FAA) concerning JT-8D model aircraft engines, CASA has issued Australian AD/JT8D/43, which will come into effect on 19 November 2009. This process ensures that Australian aircraft comply with international standards and safety requirements, thereby maintaining the safety and airworthiness of aircraft registered in Australia.
The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 impose several obligations on entities such as CASA, the State of Registry, and aircraft operators. CASA must rigorously evaluate ADs from the State of Design and, if necessary, issue corresponding Australian ADs to mandate compliance. The State of Registry must adopt or develop requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction, and aircraft operators must adhere to these requirements to maintain their aircraft's airworthiness. Failure to comply with these regulations can result in severe consequences, including the potential grounding of non-compliant aircraft and possible legal action against operators and manufacturers who do not adhere to the mandated safety standards.
There are also significant consequences for breaches of these regulations. Under the Civil Aviation Act 1988, non-compliance with ADs can result in civil penalties, including fines of up to $126,000 for individuals and $630,000 for corporations, as well as potential criminal penalties for more severe infractions. These penalties underscore the importance of adhering to airworthiness directives to ensure the safety of air navigation and the well-being of passengers and crew. The severity of these penalties reflects the high stakes involved in maintaining the airworthiness of aircraft and the critical role that ADs play in achieving this goal.
