AD/THIELERT/1 Amdt 1 - Engine Failure Due to Electrical System Failure

Overview

The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework for the regulation of civil aviation in Australia. It was introduced to address the need for a cohesive and enforceable set of regulations that ensure the safety, efficiency, and orderly development of civil aviation in the country. The Act empowers the Governor-General to make regulations under its authority, such as those concerning airworthiness directives (ADs), to further safeguard the interests of air navigation. The Civil Aviation Safety Regulations 1998, which fall under this Act, allow the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, as mandated by Annex 8 to the Convention on International Civil Aviation. This international convention assigns the State of Design the overarching responsibility for the continuing airworthiness of an aircraft type, and requires it to provide necessary information to ensure such airworthiness is maintained by relevant States of Registry. By aligning with these international standards, the Civil Aviation Act 1988 and its associated regulations help maintain high safety standards in Australia's civil aviation sector.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Regulations 1998 provide the framework under which airworthiness directives (ADs) are issued in Australia, with the objective of ensuring the safety of air navigation. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that are in the interests of safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as a crucial mechanism for maintaining the continuing airworthiness of aircraft and aeronautical products as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design, in this case Germany for Thielert Aircraft Engines GmbH Model TAE125-01 engines, has the responsibility to issue ADs for aircraft types, and the State of Registry, here represented by CASA for Australian-registered aircraft, must ensure compliance with such directives. Notably, this AD is issued without public consultation due to Australia's international obligations and is exempt from requiring a Regulatory Impact Statement. The AD is issued by CASA, under the authority granted by the Act, and it reflects the international cooperation and regulatory standards essential for ensuring global aviation safety.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations that align with the Act's objectives, particularly focusing on air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, which means that their validity can be challenged in court. The ADs are instrumental in maintaining the continuing airworthiness of aircraft, a responsibility mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design, such as Germany in the case of Thielert Aircraft Engines GmbH Model TAE125-01 engines, is tasked with overseeing the airworthiness of an aircraft type and providing essential information to ensure its continued safety. Under the Act, CASA is required to assess any ADs issued by the State of Design that affect aircraft registered in Australia. If deemed necessary, CASA can then issue its own ADs to ensure compliance with Australian standards. For instance, in response to the German LBA's AD D-2004-457 R1, CASA issued AD/THIELERT/1, Amendment 1, which became effective on 19 January 2005. This AD superseded the previous version and was made without public consultation as it was a direct response to international obligations under the Convention on International Civil Aviation. The Office of Regulatory Review has confirmed that such ADs do not require a Regulatory Impact Statement. The AD was authorised by the Section Head - Systems, Airworthiness Standards Branch, Standards Division, in accordance with subsection 84A(2) of the Act. The obligations imposed by the Act on parties and entities governed by it include the responsibility of the State of Design to provide necessary information to ensure the airworthiness of aircraft types. The State of Registry, such as Australia in this context, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. CASA, as the national airworthiness authority, must evaluate the ADs issued by the State of Design and, if necessary, issue its own ADs to address any identified safety concerns. The Act ensures that the necessary steps are taken to maintain the safety standards of air navigation by mandating these actions. In terms of consequences for non-compliance, the Act does not specify particular offences or penalties for breaches of the ADs themselves. However, non-compliance with ADs can lead to severe civil and criminal penalties under other sections of the Civil Aviation Act 1988. For example, failure to comply with ADs can result in actions under section 19 of the Act, where a person may be fined up to $126,000 for individuals and $630,000 for corporations. Additionally, non-compliance may result in the grounding of an aircraft, which can have significant operational and financial repercussions for the operator. These consequences underscore the importance of adhering to the ADs issued under the Act.
