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 United Kingdom CAA issued AD 002-11-96 affecting Dowty Rotol propellers. The United Kingdom is the State of Design for these propellers. As a result of a request from industry, CASA has amended the equivalent Australian AD to AD/PR/32 Amendment 1. The amended AD will become effective on
18 December 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a framework for ensuring the safety and efficiency of civil aviation in Australia. The Act empowers the Governor-General to create regulations that uphold the safety of air navigation, as demonstrated by the Civil Aviation Safety Regulations 1998. Regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The purpose of these directives is to ensure the continuing airworthiness of aircraft in line with international standards set by the International Civil Aviation Organization (ICAO), with the State of Design bearing primary responsibility for an aircraft type’s airworthiness and the State of Registry ensuring the airworthiness of individual aircraft. This approach aligns with Annex 8 of the Convention on International Civil Aviation, necessitating CASA to issue Australian ADs when corresponding directives are issued by the relevant State of Design.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation in Australia. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as mandated by regulation 39.001. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, and are crucial for maintaining the continuing airworthiness of aircraft as per Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA, must ensure the airworthiness of aircraft registered in Australia by issuing relevant ADs in response to directives from the State of Design. For instance, CASA issued AD/PR/32 Amendment 1 in response to a United Kingdom Civil Aviation Authority directive concerning Dowty Rotol propellers, reflecting Australia’s commitment to international aviation safety standards. These ADs do not require public consultation or a Regulatory Impact Statement, as they are issued in response to international obligations and specific safety concerns identified by the relevant State of Design.
Key Provisions
The key operative sections of this legislation require the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing safety of aircraft in Australian airspace. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to issue ADs for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that CASA can act swiftly and effectively to address safety issues by mandating compliance with ADs, which are aligned with international standards set out in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by this Act on CASA and the parties it governs include ensuring that ADs are issued in response to safety concerns identified by the State of Design and that they are effectively communicated to the relevant stakeholders. CASA must evaluate any ADs issued by the State of Design and, if necessary, issue corresponding ADs for Australian-registered aircraft to maintain compliance with international safety standards. The State of Registry of an individual aircraft, typically CASA, has the responsibility to enforce these ADs and ensure that all aircraft within its jurisdiction remain airworthy. This entails implementing rigorous checks and maintenance protocols to verify that the ADs are followed, thereby safeguarding the safety of air travel.
Failure to comply with the ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD is considered an offence. The Act provides for both civil and criminal penalties for breaches, although the specific penalties are not detailed in this excerpt. The severity of the penalties depends on the nature and extent of the non-compliance. Civil penalties may include fines, while criminal penalties could result in imprisonment, reflecting the high stakes involved in ensuring the safety of aviation. The legislative framework thus serves as a deterrent against non-compliance, ensuring that all parties involved in civil aviation adhere to the highest safety standards.
