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 United States FAA has corrected AD 2007-11-07 affecting Boeing 737 model aircraft. The United States is the State of Design for this type. CASA has assessed the corrected AD and has issued Australian AD/B737/303, Amendment 1, which will become effective on 31 August 2007. This AD cancels and replaces the previous issue.
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, 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 legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. One significant aspect of this Act is the issuance of airworthiness directives (ADs), which are regulatory measures mandated to maintain the airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, empowering the Civil Aviation Safety Authority (CASA) to issue ADs as necessary for the safety of air navigation. In accordance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, must ensure that these international standards are met within Australian jurisdiction. The AD in question, issued in response to an AD from the United States Federal Aviation Administration concerning Boeing 737 model aircraft, exemplifies the collaborative international approach to maintaining aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, aiming to ensure the safety of air navigation. These directives are legislative instruments, subject to disallowance, and are issued in response to international obligations under the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of aircraft types, and CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to align with directives from the relevant State of Design. For instance, CASA has issued Australian AD/B737/303, Amendment 1, following the United States’ correction of AD 2007-11-07 concerning Boeing 737 model aircraft. This AD, effective from 31 August 2007, replaces the previous issue and is issued without public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD is made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, under the authority granted by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This authority is exercised under section 98 of the Civil Aviation Act 1988, with the overarching aim of ensuring the safety of air navigation. These ADs are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901 and are legislative instruments under section 6 of the Legislative Instruments Act 2003. In this context, an AD is a formal directive issued to address safety concerns, ensuring that aircraft maintain their airworthiness through necessary modifications or inspections.
The obligations imposed by these ADs are significant for both the State of Registry and the aircraft operators. The State of Registry, which in Australia is CASA, is mandated to evaluate and, if necessary, issue an Australian AD in response to directives from the State of Design. This ensures that Australian aircraft comply with international safety standards and continue to be airworthy. Aircraft operators, on the other hand, must adhere to the requirements set out in the ADs. This includes following the specified maintenance actions, inspections, and operational limitations to ensure that their aircraft meet the necessary safety standards. Failure to comply with these directives can result in the aircraft being grounded, thereby compromising flight safety.
Violations of the requirements set out in airworthiness directives can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties can include fines, and in severe cases, criminal penalties may apply, which could result in imprisonment. The exact penalties are determined by the nature and severity of the breach but are intended to enforce strict adherence to the safety regulations. The enforcement of these directives is critical to maintaining the high safety standards required in civil aviation.
