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 2005-20-03 affecting Boeing 737 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/250, which will become effective on 24 November 2005.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, establishes the framework for ensuring the safety of air navigation in Australia. It empowers the Governor-General to create regulations aimed at maintaining the safety of air navigation, which includes the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, as outlined in the Legislative Instruments Act 2003, and are critical for ensuring the continuing airworthiness of aircraft types, in line with Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA), as Australia’s national airworthiness authority, assesses ADs issued by States of Design and, if deemed necessary, issues corresponding Australian ADs to mandate the required safety measures. This legislative structure ensures that Australia adheres to international standards for aircraft safety and airworthiness.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. The Act empowers the Governor-General to create regulations under section 98 to promote the safety of air navigation, and regulation 39.001 specifically authorises the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are legislative instruments, as they fall under the purview of the Legislative Instruments Act 2003 and the Acts Interpretation Act 1901. The ADs serve to implement Australia’s obligations under international agreements, such as Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for the continuing airworthiness of an aircraft type, and mandates that States of Registry must ensure the airworthiness of aircraft within their jurisdiction. CASA, as Australia's national airworthiness authority, must act on ADs issued by the State of Design, assessing their applicability and issuing corresponding Australian ADs as necessary. For instance, in the case of AD 2005-20-03 issued by the US Federal Aviation Administration concerning Boeing 737 aircraft, CASA issued Australian AD/B737/250, reflecting Australia's commitment to international safety standards and ensuring compliance with domestic regulations.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for airworthiness directives (ADs), with section 98 of the Act and regulation 39.001 of the Regulations specifically addressing the issuance of these directives. According to regulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. This means that ADs carry legal weight and must be adhered to by relevant parties. Under Annex 8 of the Convention on International Civil Aviation, the State of Design, which is the country responsible for designing a particular aircraft type, has the overarching responsibility for ensuring the aircraft's continuing airworthiness. This includes providing necessary information to States of Registry, which are the countries where the aircraft is registered and thus responsible for its day-to-day airworthiness. In Australia, the Civil Aviation Safety Authority (CASA) is tasked with assessing information from States of Design and issuing Australian ADs when necessary.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 place significant responsibilities on CASA and the States of Registry. CASA, as Australia's national airworthiness authority, must assess any ADs issued by States of Design and determine whether Australian ADs are necessary. If so, CASA must issue these directives to ensure compliance with international standards. The States of Registry, on the other hand, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within their jurisdictions. This includes implementing the mandates set forth in ADs issued by CASA. By fulfilling these obligations, CASA and States of Registry ensure that aircraft operating in Australian airspace meet the required safety standards.
Failure to comply with ADs can lead to significant consequences. Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, non-compliance with ADs can result in serious safety risks, potentially leading to criminal or civil penalties. Specifically, section 104 of the Act provides for civil penalties, including fines, for non-compliance. Additionally, under section 108, CASA can issue infringement notices for minor breaches, which carry financial penalties. For more serious breaches, CASA may refer cases to the Australian Federal Police, leading to criminal charges and potential imprisonment. The exact penalties depend on the severity of the breach and are determined by the courts. It is crucial for all parties governed by these regulations to comply with ADs to avoid these serious consequences.
