AD/CESSNA 210/74 - Alternate Static Air Source Valve

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Under this Act, the Governor-General has the authority to make regulations necessary for the purposes of the Act, as per section 98. The Civil Aviation Safety Regulations 1998, made under this Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products through regulation 39.001. These ADs, which are legislative instruments, serve to maintain the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, with the State of Design bearing overall responsibility. CASA, as the national airworthiness authority, must respond to ADs issued by the State of Design by assessing the information and, if necessary, issuing corresponding Australian ADs to ensure compliance with international safety standards. The issuance of these Australian ADs is a direct response to obligations under the Convention on International Civil Aviation and the ADs raised by the relevant State of Design, which in this case is the United States for certain Cessna aircraft series. The ADs issued by CASA, as detailed in Schedule 1 and effective from 13 May 2008, have been determined not to require public consultation or a Regulatory Impact Statement. They have been promulgated by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.

Scope and Application

The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation. These regulations apply to all aircraft registered in Australia and their operators, extending to the geographic jurisdiction of Australia. ADs, which are legislative instruments under the Legislative Instruments Act 2003, are issued in response to international obligations under the Convention on International Civil Aviation, particularly in coordination with the State of Design of the aircraft. The State of Registry, in this case CASA, is mandated to ensure the continuing airworthiness of the aircraft, requiring compliance with any ADs issued by CASA or those issued by the relevant State of Design. The ADs are made under the authority granted by the Act and are not subject to disallowance as they are necessary to maintain international safety standards. The issuance of these directives does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.

Key Provisions

The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are sections 98 and 39.001 respectively. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to 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) is authorised to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. The specific subregulation, 39.001(5), further defines an AD as a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901, thereby making it a legislative instrument. These provisions impose obligations on CASA as the national airworthiness authority in Australia. Under Annex 8 to the Convention on International Civil Aviation, the State of Design, in this case, the United States, has overall responsibility for the continuing airworthiness of an aircraft type. CASA is required to assess the information provided by the State of Design and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that aircraft registered in Australia continue to meet airworthiness standards. Failure to comply with the requirements outlined in an AD can lead to significant consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties for non-compliance with ADs, the broader aviation safety framework in Australia could impose severe penalties. Non-compliance with airworthiness directives can lead to enforcement actions, including grounding of aircraft, fines, and potential criminal charges for operators who fail to adhere to the mandated safety standards. The severity of the penalties depends on the nature and extent of the non-compliance, but the overarching aim is to ensure that all aircraft continue to operate safely. Additionally, it is important to note that the issuing of these ADs is in response to Australia's obligations under the Convention on International Civil Aviation, and as such, no consultation of the Australian public has taken place. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, highlighting the urgency and importance of these measures in maintaining air safety. The ADs are issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that the process is both accountable and transparent within the legislative framework.
