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 2007-17-17 affecting Learjet 35 and 36 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/LEARJET 35/41, which will become effective on 25 October 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, Airframes 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 Australian Parliament, was introduced to establish a comprehensive framework for ensuring the safety of air navigation and the regulation of civil aviation within Australia. The Act provides the legal basis for the creation of safety regulations and directives, including airworthiness directives (ADs), to maintain the highest standards of aviation safety. In accordance with section 98 of the Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This legislative structure ensures that Australia can effectively implement international safety standards and respond to safety concerns raised by the State of Design, such as the United States in the case of Learjet models 35 and 36, where CASA issued AD/LEARJET 35/41 following an AD from the US Federal Aviation Administration (FAA).
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, governed by the Civil Aviation Act 1988, mandate that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives, which are legislative instruments under the Acts Interpretation Act 1901, serve to ensure the ongoing airworthiness of aircraft in accordance with international standards set by the Convention on International Civil Aviation. Specifically, ADs are a critical mechanism for communicating safety requirements to the State of Registry, which is responsible for the individual aircraft’s continuing airworthiness. In the context of Australia, CASA, as the national airworthiness authority, must evaluate and, if necessary, implement Australian ADs based on directives issued by the State of Design, such as the US Federal Aviation Administration (FAA) in the case of Learjet 35 and 36 models. The issuance of these directives does not require public consultation or a Regulatory Impact Statement, as they are integral to fulfilling Australia's obligations under international aviation conventions.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. They play a crucial role in ensuring the continuing airworthiness of aircraft types, particularly when issued in response to directives from the State of Design as outlined in Annex 8 to the Convention on International Civil Aviation. For example, in the case of Learjet 35 and 36 models, CASA issued Australian AD/LEARJET 35/41 after evaluating a directive from the US Federal Aviation Administration (FAA), the State of Design for these aircraft.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other relevant authorities include the assessment and implementation of ADs to ensure the safety of aircraft registered in Australia. The State of Design is responsible for issuing ADs for aircraft types, and the State of Registry, in this case CASA, must ensure that these directives are appropriately adopted and enforced within Australia. The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of aircraft. This involves closely monitoring and responding to ADs issued by the State of Design to maintain compliance with international safety standards.
Failure to comply with airworthiness directives can result in significant consequences, both civil and criminal. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to penalties. The exact penalties are not specified in the text but typically include fines and potential imprisonment for more serious breaches. The severity of the penalty may depend on the nature and extent of the non-compliance, with repeat offenders or those causing significant safety risks facing harsher penalties. Additionally, non-compliance can result in aircraft being grounded, thereby disrupting operations and potentially leading to more severe incidents.
In summary, the key provisions of the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower CASA to issue ADs to ensure the continuing airworthiness of aircraft in Australia. The obligations on CASA and other authorities include the diligent assessment and enforcement of these directives. The potential consequences for non-compliance include civil penalties and criminal charges, highlighting the critical importance of adhering to these regulations to maintain aviation safety standards.
