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.
Transport Canada has issued AD CF-2008-17 affecting Eurocopter Canada BO 105 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BO 105/16, Amendment 1, which will become effective on 27 May 2008. This AD cancels and replaces the previous issue.
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 provide a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of the aviation industry. This Act empowers the Governor-General to create regulations that are integral to the safety of air navigation, including the issuance of airworthiness directives (ADs) as stipulated under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that CASA can issue to mandate continuing airworthiness requirements for specific types of aircraft or aeronautical products. The Civil Aviation Act 1988 thus addresses the need for a cohesive and enforceable regulatory framework that aligns with international standards, ensuring that the safety and airworthiness of aircraft operating in Australian airspace are consistently maintained. The policy objective of the Act is to uphold the highest safety standards in civil aviation, thereby protecting the public and promoting the responsible operation of aircraft.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as mandated by section 98 of the Civil Aviation Act 1988. These directives, considered disallowable instruments under the Acts Interpretation Act 1901, are legislative instruments in their own right as per section 6 of the Legislative Instruments Act 2003. ADs are integral to ensuring the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design, such as Canada for the Eurocopter Canada BO 105 model helicopters, must provide necessary information for airworthiness, which CASA then assesses and, if necessary, translates into Australian ADs. This AD, issued in response to Transport Canada’s AD CF-2008-17, mandates compliance with the specified requirements and becomes effective on 27 May 2008. Given its international basis and the absence of consultation with the Australian public, this AD does not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This is a key provision under section 98 of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations for the safety of air navigation. The ADs are legislative instruments, as outlined in section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs serve as a means to ensure the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry, which then implement the ADs for individual aircraft.
The obligations imposed by these ADs on the parties or entities they govern are significant. The State of Design must provide information to ensure the continuing airworthiness of an aircraft type. In turn, the State of Registry is responsible for implementing the ADs to ensure that individual aircraft remain airworthy. CASA, as Australia’s national airworthiness authority, must assess any AD issued by the State of Design and, if necessary, issue an Australian AD to enforce the requirements. This was exemplified by the issuance of Australian AD/BO 105/16, Amendment 1, in response to Transport Canada’s AD CF-2008-17 affecting Eurocopter Canada BO 105 model helicopters. Such directives ensure that safety standards are uniformly applied across all aircraft of the specified type within Australia.
Failure to comply with the ADs can result in serious consequences. The Civil Aviation Safety Regulations 1998 do not specify particular offences or penalties for non-compliance with ADs. However, non-compliance generally leads to legal actions and penalties under other sections of the Civil Aviation Act 1988, which can include fines and imprisonment. The severity of the penalties will depend on the specific breach and the discretion of the courts. Additionally, non-compliance can result in the grounding of aircraft, which can have significant operational and financial repercussions for operators. The overarching aim of these regulations is to maintain high safety standards in the aviation industry, and thus compliance is strictly enforced.
