AD/DO 328/71 - Wing Lower Inner Panel

Overview

The Civil Aviation Act 1988 was enacted to ensure the safety and efficiency of civil aviation in Australia. The Act provides the legislative framework for the regulation of civil aviation in Australia, including the establishment of the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. The 1998 Civil Aviation Safety Regulations, made under the authority of the Act, detail the procedures for ensuring the continuing airworthiness of aircraft and aeronautical products. Regulation 39.001 specifically empowers CASA to issue airworthiness directives, which are legislative instruments that mandate compliance with safety requirements. This legislative framework is designed to align with international standards set by the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and the State of Registry for ensuring aircraft airworthiness. The issuance of airworthiness directives, such as AD/DO 328/71 in response to EASA’s AD 2008-0087-E, is a direct result of Australia’s commitment to these international obligations and ensures the safety and uniformity of airworthiness standards across the industry.

Scope and Application

The Civil Aviation Safety Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the Governor-General to establish regulations for the safety of air navigation, including the issuance of airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. Pursuant to regulation 39.001 of these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue such directives. An AD is recognised as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and consequently, a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These directives are fundamental to ensuring the continuing airworthiness of aircraft and are issued by most International Civil Aviation Organization (ICAO) Contracting States. The State of Registry of an individual aircraft bears the responsibility for its ongoing airworthiness, a duty that involves developing or adopting requirements to maintain airworthiness standards in accordance with Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must evaluate any ADs issued by a State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce these requirements on registered aircraft within Australia.

Key Provisions

The Civil Aviation Act 1988, specifically under section 98, allows the Governor-General to create regulations that contribute to the safety of air navigation. The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. It is important to note that under subregulation 39.001(5), an AD is considered a disallowable instrument, and as such, it is a legislative instrument according to section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design overall responsibility for this aspect. In accordance with the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA is responsible for assessing airworthiness directives issued by the State of Design and, if necessary, issuing corresponding Australian ADs to ensure compliance with safety requirements. For instance, in the case of the Dornier 328 model aircraft, the European Aviation Safety Authority (EASA) issued AD 2008-0087-E on behalf of Germany, the State of Design. CASA evaluated this AD and subsequently issued Australian AD/DO 328/71, which will take effect on 9 May 2008. Given that this AD was issued due to Australia's obligations under the Convention on International Civil Aviation, and as a response to an AD raised by the relevant State of Design, no public consultation was required. Moreover, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in compliance with subsection 84A(2) of the Act. The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 primarily revolve around the assessment and issuance of airworthiness directives by CASA. This involves the evaluation of information provided by the State of Design and the subsequent implementation of Australian ADs to guarantee the continuing airworthiness of aircraft on the Australian Register. CASA must adhere to the guidelines set forth in Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design has overall responsibility for the airworthiness of an aircraft type and must provide any necessary information to the appropriate States of Registry. Furthermore, CASA must ensure that States of Registry develop or adopt requirements to ensure the continuing airworthiness of aircraft. In terms of consequences for non-compliance with the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, breaches of airworthiness directives may result in both civil and criminal penalties. Civil penalties may include fines and the imposition of administrative penalties, while criminal penalties may entail imprisonment, fines, or both, depending on the severity of the offence. The specific maximum penalties for breaches of the Act and Regulations are not explicitly stated in the provided text, but they may be found in other sections of the legislation or in related statutes. It is essential for all parties and entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 to adhere to the stipulated airworthiness directives to ensure the safety of air navigation and the continued airworthiness of aircraft.
