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 2008-08-22 affecting Boeing B737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/324, which will become effective on 5 June 2008.
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 Parliament of Australia, serves as the foundational legislation governing civil aviation within the country. This Act was introduced to address the need for a comprehensive regulatory framework ensuring the safety and efficiency of civil aviation operations in Australia. The Act provides the Civil Aviation Safety Authority (CASA) with the authority to issue regulations, including airworthiness directives, to maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower CASA to issue airworthiness directives for certain types of aircraft or aeronautical products, thereby enforcing compliance with safety standards. These directives are considered legislative instruments under the Legislative Instruments Act 2003. The policy objective of the Act, as reinforced by these regulations, is to ensure that air navigation remains safe and efficient, aligning with Australia's obligations under international civil aviation conventions.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) having the authority to issue such directives under regulation 39.001. These ADs apply to all types of aircraft and aeronautical products within Australia, ensuring the safety of air navigation and compliance with international standards as set forth by the Convention on International Civil Aviation. The ADs are legislative instruments, disallowable under the Acts Interpretation Act 1901, and are developed in response to assessments by CASA based on information provided by the State of Design. For instance, in the case of Boeing B737 model aircraft, the United States, as the State of Design, issued an AD which CASA subsequently assessed and translated into an Australian AD. This process is conducted in adherence to Australia's obligations under international aviation agreements, and as such, does not involve public consultation or require a Regulatory Impact Statement. The ADs are issued by CASA in accordance with the Act, ensuring that all aircraft registered in Australia meet the necessary safety standards.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework under which the Civil Aviation Safety Regulations 1998 are made, including the issuance of airworthiness directives (ADs) (sections 98 and 39.001). Regulation 39.001(5) of these Regulations classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and hence as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. ADs are essential tools in ensuring the continuing airworthiness of aircraft types and are issued by most ICAO Contracting States, including the United States for the Boeing B737 model aircraft. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry, which in turn must develop or adopt requirements to ensure airworthiness. In this instance, the US Federal Aviation Administration (FAA) issued AD 2008-08-22 for Boeing B737 aircraft, prompting CASA to issue Australian AD/B737/324, which will become effective on 5 June 2008.
The obligations imposed on parties by this AD include adherence to the specific requirements outlined in the directive, which are necessary to maintain the airworthiness of the aircraft. The AD mandates certain actions or inspections that must be performed on the aircraft, and it specifies the timeframe within which these actions must be completed. Operators of the affected aircraft must ensure that their maintenance schedules and procedures comply with the AD, and they must document any actions taken in accordance with the directive. Failure to comply with the AD could result in the aircraft being deemed unairworthy, which could lead to grounding of the aircraft and cessation of flight operations. Additionally, operators must report any non-compliance with the AD to CASA, as the AD is a legislative instrument subject to oversight by the Australian government.
Breaches of the AD can lead to serious consequences, including both civil and criminal penalties. Under section 84A of the Civil Aviation Act 1988, any person who contravenes an AD commits an offence. The maximum penalty for contravening an AD is a fine of up to 200 penalty units (approximately AUD 41,000 as of 2023) for individuals, and up to 1,000 penalty units (approximately AUD 205,000) for bodies corporate. Furthermore, CASA has the authority to issue infringement notices for minor breaches of the AD, with penalties typically ranging from AUD 500 to AUD 2,500. In addition to financial penalties, operators may face operational restrictions, such as being prohibited from flying the affected aircraft until compliance is demonstrated. These measures underscore the importance of adhering to ADs to maintain the safety and airworthiness of aircraft.
