AD/AC/37 - Cockpit Windows - Modification - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide a framework for the regulation of civil aviation in Australia, with a strong emphasis on safety and airworthiness. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that mandate the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) issues these directives for aircraft on the Australian register, ensuring compliance with international standards and the specific obligations of the State of Registry. The cancellation of AD/AC/37 for Twin Aero Commander 680T and 680V aircraft models is a direct result of Australia's obligations under the Convention on International Civil Aviation. CASA, as the national airworthiness authority, assessed the information provided by the State of Design and determined that the unsafe condition necessitating the AD no longer exists, leading to the cancellation of the directive effective 31 July 2008. This action was taken without public consultation, as it was deemed unnecessary, and no Regulatory Impact Statement was required. The AD cancellation was made by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act.

Scope and Application

The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations apply to entities involved in the aviation industry, including aircraft manufacturers, operators, and maintenance providers. The primary objective of these regulations is to ensure the safety of air navigation by mandating compliance with specific airworthiness requirements for aircraft and aeronautical products. The authority to issue ADs is derived from section 98 of the Act and regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empower CASA to issue ADs for kinds of aircraft or aeronautical products. Each AD is considered a legislative instrument and can be disallowed under the Acts Interpretation Act 1901. ADs are integral to the continuing airworthiness of aircraft, with the State of Design having the overarching responsibility and the State of Registry tasked with ensuring that specific aircraft meet airworthiness standards. In the case of AD/AC/37 concerning Twin Aero Commander 680T and 680V aircraft models, CASA has determined that the unsafe condition no longer exists, leading to the cancellation of the AD on 31 July 2008 without the need for a replacement. The cancellation of this AD was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required.

Key Provisions

The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 involve the issuance of airworthiness directives (ADs). Specifically, section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Regulations empowers CASA to issue ADs for certain kinds of aircraft or aeronautical products. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments according to section 6 of the Legislative Instruments Act 2003. These provisions facilitate the continuous monitoring and maintenance of aircraft safety standards as per international agreements. The obligations imposed on parties by the Act and the Regulations are primarily focused on the State of Design and the State of Registry. The State of Design, which is the country where the aircraft type was designed, must provide necessary information to ensure the continuing airworthiness of the aircraft type. This information typically comes in the form of ADs. The State of Registry, which is the country where the individual aircraft is registered, is responsible for implementing these requirements to maintain the airworthiness of the aircraft. CASA, as Australia's national airworthiness authority, must assess the ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the required safety measures. The Civil Aviation Safety Regulations 1998, under regulation 39.001(5), classify ADs as disallowable instruments, which means that they can be reviewed and disallowed by Parliament. However, in this case, the cancellation of AD/AC/37 was made due to Australia's obligations under the Convention on International Civil Aviation, and therefore, no public consultation or Regulatory Impact Statement was required. The AD cancellation was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. There are no explicit offences or penalties mentioned in the text for the issuance or compliance with ADs. However, the overarching framework implies that failure to comply with ADs could potentially lead to legal consequences, as non-compliance with airworthiness requirements may be considered a breach of the Civil Aviation Act 1988. The specific penalties for such breaches are not detailed in the provided text but would typically involve fines or other sanctions as determined by relevant aviation authorities. The Act and the Regulations focus on ensuring the continuous safety and airworthiness of aircraft through the effective use of ADs.
