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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/PA-31/28 affecting Piper PA-31 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 air navigation and operations. This legislation empowers the Governor-General to make regulations, such as those pertaining to the issue of airworthiness directives (ADs), which are crucial for maintaining the safety standards of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 further specify the authority of the Civil Aviation Safety Authority (CASA) to issue ADs, which serve as a legislative instrument for continuing airworthiness of aircraft types. The ADs are aligned with the requirements under Annex 8 to the Convention on International Civil Aviation, ensuring that both the State of Design and the State of Registry uphold their responsibilities for aircraft airworthiness.
In line with its obligations under the Convention on International Civil Aviation, CASA has reviewed and subsequently cancelled AD/PA-31/28, which affected Piper PA-31 aircraft. This cancellation, effective from 31 July 2008, was enacted without public consultation as it pertains to Australia’s international obligations, and it does not necessitate a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the relevant legislative provisions.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the overarching framework of the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These regulations apply to all aircraft and aeronautical products within Australia, and are made in accordance with international standards set by the Convention on International Civil Aviation, specifically Annex 8 which addresses the continuing airworthiness of aircraft. ADs are essential for maintaining the airworthiness of individual aircraft and are a legislative instrument that can be disallowed under the Acts Interpretation Act 1901. The State of Design and the State of Registry both have specific responsibilities under these regulations, with the former responsible for providing information necessary for continuing airworthiness and the latter for developing or adopting requirements to ensure it. Notably, CASA has the authority to issue and cancel these directives, as demonstrated by the recent cancellation of AD/PA-31/28 affecting Piper PA-31 aircraft, effective from 31 July 2008, without a need for public consultation or a Regulatory Impact Statement due to its alignment with international obligations.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (39.001). These directives are formal instructions issued by CASA to ensure the safety and airworthiness of aircraft, and they are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 (39.001(5)). Furthermore, as per section 6 of the Legislative Instruments Act 2003, ADs are recognised as legislative instruments. Annex 8 of the Convention on International Civil Aviation assigns the State of Design the responsibility for the ongoing airworthiness of an aircraft type, necessitating the provision of relevant information to States of Registry. Conversely, the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft, in line with the requirements outlined in Annex 8.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to issue ADs for specified aircraft or aeronautical products to maintain airworthiness and safety standards. The State of Design must provide necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry must implement or adopt requirements to ensure the airworthiness of individual aircraft. CASA, acting in accordance with its powers under section 84A(2) of the Civil Aviation Act 1988, issued AD/PA-31/28 for Piper PA-31 aircraft, but has subsequently cancelled this AD, effective from 31 July 2008. This cancellation is due to Australia's obligations under the Convention on International Civil Aviation, and no replacement AD is required.
Breaches of airworthiness directives or failure to comply with the requirements of the Civil Aviation Safety Regulations 1998 may result in serious safety implications and potential legal consequences. The maximum penalties for non-compliance can include substantial fines and imprisonment, depending on the severity of the breach. The specific penalties are outlined in the Civil Aviation Act 1988 and the Civil Aviation Regulations 1988, which provide for both civil and criminal liabilities for those who fail to adhere to the regulations. Ensuring compliance with ADs is critical for maintaining the safety of air navigation and the public.
In conclusion, the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, establish the framework for CASA to issue airworthiness directives to ensure the safety and airworthiness of aircraft. The obligations on CASA, the State of Design, and the State of Registry are clearly defined, with significant consequences for non-compliance. The cancellation of AD/PA-31/28 by CASA, due to international obligations, highlights the importance of adhering to global standards in aviation safety. The legislative instruments, including ADs, play a crucial role in upholding these standards and ensuring the safety of air navigation.
