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 UK CAA has issued AD 008-11-95 affecting BAe Jetstream 4100 model aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/8, which will become effective on 20 February 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 Australian Parliament, establishes a regulatory framework aimed at ensuring the safety of air navigation within Australia. One of the Act's key provisions is its authorisation for the Governor-General to create regulations in the interests of air navigation safety, as seen in the issuance of airworthiness directives. These directives are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products, as outlined in the Civil Aviation Safety Regulations 1998. In line with international standards set by the Convention on International Civil Aviation, the State of Design is responsible for ensuring the airworthiness of aircraft types, with the State of Registry overseeing the airworthiness of individual aircraft. CASA, Australia’s national airworthiness authority, plays a pivotal role in this process by assessing information from the State of Design and issuing corresponding Australian airworthiness directives where necessary. This legislative framework ensures that Australia complies with international obligations and maintains high safety standards in civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specific kinds of aircraft or aeronautical products in order to maintain safety standards in air navigation, as authorised under section 98 of the Civil Aviation Act 1988. These ADs, considered legislative instruments under section 46A of the Acts Interpretation Act 1901, are essential for ensuring the continuing airworthiness of aircraft types and products. The ADs align with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design has overarching responsibility for an aircraft type’s airworthiness, and the State of Registry is tasked with ensuring the airworthiness of individual aircraft. In practice, this means CASA, acting as Australia's national airworthiness authority, must evaluate ADs issued by the State of Design and, when necessary, issue corresponding Australian ADs to enforce the required safety measures. These directives are integral to maintaining the safety and operational standards of aircraft registered in Australia.
Key Provisions
The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 (paragraph 5), which serve as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. These ADs are intended to maintain the safety standards of air navigation, aligning with the overarching responsibility of the State of Design for the continuing airworthiness of an aircraft type as stipulated in Annex 8 of the Convention on International Civil Aviation. The State of Registry, such as CASA in Australia, must ensure compliance with these directives to uphold the aircraft's airworthiness.
The obligations imposed by these regulations are multifaceted. The State of Design, in this case, the United Kingdom Civil Aviation Authority (UK CAA), is responsible for issuing ADs that address safety concerns for specific aircraft types. Upon receipt of such directives, CASA must rigorously assess the ADs to determine their applicability and necessity within Australia. If deemed appropriate, CASA issues corresponding Australian ADs, such as AD/J4100/8, which set forth mandatory requirements for aircraft operators. This ensures that all aircraft registered in Australia meet international safety standards.
Failure to comply with the ADs can result in severe consequences. Under section 98 of the Civil Aviation Act 1988, non-compliance with an AD can be classified as an offence. Such breaches may attract penalties, the specifics of which can include fines and other sanctions. The precise penalties are not detailed in the provided text, but they underscore the importance of adhering to the mandated safety standards. The stringent nature of these regulations reflects the critical importance of maintaining high safety standards in aviation.
In summary, the ADs issued by CASA under the Civil Aviation Safety Regulations 1998 are pivotal in ensuring the safety and airworthiness of aircraft operating within Australia. These directives, derived from international standards and obligations, impose significant responsibilities on both the State of Design and the State of Registry. Compliance is mandatory, and failure to adhere to these directives can result in legal repercussions, emphasising the paramount importance of these safety measures.
