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 FAA has issued AD 2005-25-26 affecting Boeing Model 747 aircraft. USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/339, which will become effective on 16 March 2006.
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 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a focus on safety and efficiency within the industry. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. Among these regulations, the Civil Aviation Safety Regulations 1998 outline the procedures for issuing airworthiness directives (ADs) that are essential for maintaining the safety standards of aircraft and aeronautical products. The Act aims to ensure that Australia’s aviation practices align with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The ADs are critical tools in this regard, facilitating the communication of safety requirements from the State of Design to the State of Registry, thereby ensuring that aircraft registered in Australia meet necessary safety criteria. The Civil Aviation Safety Regulations 1998 further detail that ADs are legislative instruments subject to disallowance and review processes, underpinning the rigorous approach taken to safeguard air travel.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, mandates the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, under section 98 of the Act, the Governor-General may make regulations that govern the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for particular types of aircraft or aeronautical products. These directives are legislative instruments and are essential for ensuring the continuing airworthiness of aircraft, a responsibility held by both the State of Design and the State of Registry. When the United States, as the State of Design for Boeing Model 747 aircraft, issues an AD, CASA must assess and, if appropriate, issue a corresponding Australian AD to ensure compliance with international standards under the Convention on International Civil Aviation. The AD in question, issued by CASA in response to FAA's AD 2005-25-26, will become effective on 16 March 2006 and is issued without public consultation due to Australia's international obligations.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. This regulatory framework includes the Civil Aviation Safety Regulations 1998, which under regulation 39.001, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD, as defined in subregulation 39.001(5), is classified as a disallowable instrument under the Acts Interpretation Act 1901 and, as such, it is considered a legislative instrument in accordance with the Legislative Instruments Act 2003. These directives are crucial for maintaining the continuing airworthiness of aircraft, a responsibility ultimately resting with the State of Design as per Annex 8 to the Convention on International Civil Aviation.
Under these regulations, CASA, as Australia's national airworthiness authority, has a duty to ensure the safety and airworthiness of aircraft registered in Australia. When an AD is issued by the State of Design, CASA must assess the information provided and, if necessary, issue a corresponding Australian AD to mandate the required safety measures. For example, the Federal Aviation Administration (FAA) has issued AD 2005-25-26 concerning Boeing Model 747 aircraft, and CASA has subsequently issued Australian AD/B747/339, effective from 16 March 2006. This process underscores Australia's commitment to international civil aviation standards and ensures that aircraft operating within its jurisdiction meet stringent safety requirements.
Entities and individuals governed by these regulations must adhere to the directives issued by CASA. Operators of aircraft affected by ADs are required to implement the necessary maintenance, repair, or alteration actions within specified timeframes. Failure to comply with an AD can result in severe consequences, including potential grounding of the aircraft, fines, and other legal penalties. The ADs serve as a direct mandate for ensuring that all aircraft continue to meet the required safety standards, and it is the responsibility of the aircraft owner or operator to ensure compliance with these directives.
In terms of legal consequences, breaches of ADs are taken very seriously under the Civil Aviation Act 1988 and the associated regulations. Non-compliance can result in civil penalties, including fines and potential criminal charges for serious violations. The maximum penalties may vary depending on the severity of the breach, but they are designed to ensure that air safety is not compromised. Additionally, CASA has the authority to take enforcement actions, which may include grounding the aircraft until compliance is achieved. These stringent measures are intended to maintain the highest standards of airworthiness and ensure the safety of passengers and crew.
