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 73-19-09 affecting OH-58A (BELL 206A-1) model helicopters. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/OH-58/3, which will become effective on
28 August 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 was enacted to regulate civil aviation in Australia with a focus on ensuring the safety of air navigation. This Act empowers the Governor-General to create regulations aimed at maintaining the safety of air navigation, including the issuance of airworthiness directives (ADs) to ensure aircraft remain airworthy. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions by allowing the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are critical in enforcing the continuing airworthiness of aircraft and are issued in compliance with international standards set by the International Civil Aviation Organization (ICAO).
The introduction of the AD for OH-58A (BELL 206A-1) model helicopters, issued by CASA in response to a similar directive by the US Federal Aviation Administration (FAA), demonstrates Australia's commitment to international safety standards and obligations under the Convention on International Civil Aviation. This AD, which becomes effective on 28 August 2008, was issued without public consultation as it aligns with Australia's international obligations and was evaluated by CASA. The AD was created by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative framework established by the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework within which airworthiness directives (ADs) are issued to ensure the safety of aircraft in Australian airspace. Under this legislation, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, which are legislative instruments, are designed to maintain and ensure the continuing airworthiness of aircraft registered in Australia, aligning with obligations under the Convention on International Civil Aviation and the responsibilities of the State of Design and State of Registry. The application of these ADs is geographically broad, covering all aircraft registered in Australia, and they are often issued in response to directives from the relevant State of Design, such as the United States Federal Aviation Administration (FAA), without necessitating public consultation. While these ADs are critical for safety, they are exempt from certain regulatory scrutiny such as the requirement for a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, as amended and in conjunction with the Civil Aviation Safety Regulations 1998, allows for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 98 of the Act, the Governor-General has the authority to make regulations in the interest of air navigation safety. Regulation 39.001 specifically grants CASA the power to issue ADs for types of aircraft or aeronautical products, as stated in subregulation 39.001(5). These directives are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations placed on the parties by this Act are multifaceted. The State of Design, in this case, the USA for OH-58A (BELL 206A-1) model helicopters, bears the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure compliance with airworthiness standards. Correspondingly, the State of Registry, here being Australia, must develop or adopt requirements to maintain the continuing airworthiness of aircraft registered within its jurisdiction. CASA, acting as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and, when necessary, issue corresponding Australian ADs to mandate the required compliance measures.
Failure to adhere to the requirements set forth in these airworthiness directives can result in serious consequences. Civil or criminal penalties may be imposed depending on the nature and severity of the non-compliance. Under the Civil Aviation Act 1988, violations can lead to substantial fines, with the exact amount determined by the court. Additionally, ongoing non-compliance can result in the grounding of affected aircraft, which can significantly impact operational and economic activities. Given the stringent nature of these regulations, it is imperative for all parties involved to strictly follow the mandated requirements to avoid any legal repercussions.
