AD/TB10/13 - Aircraft Wiring/Support Bracket Clearance - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to establish a regulatory framework for ensuring the safety of civil aviation within Australia. This legislation was introduced to address the need for a comprehensive set of laws governing the operation of civil aircraft, with a primary focus on safety and compliance. The Act empowers the Governor-General to create regulations that promote the safety of air navigation, delegating specific enforcement and regulatory tasks to the Civil Aviation Safety Authority (CASA). CASA, under regulation 39.001 of the Civil Aviation Safety Regulations 1998, is authorised to issue airworthiness directives (ADs) that are critical for maintaining the continuing airworthiness of aircraft and aeronautical products. This legislative mechanism aligns with international standards as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry bear responsibilities for ensuring aircraft safety and airworthiness. The ADs are legislative instruments as per the Legislative Instruments Act 2003, and their issuance and cancellation reflect CASA’s commitment to adhering to both domestic and international aviation safety standards. In the case of AD/TB10/13 affecting SOCATA TB10 aircraft, CASA reviewed and subsequently cancelled the directive in accordance with Australia’s obligations under the Convention on International Civil Aviation. This cancellation took effect on 2 July 2009, with no replacement AD required. The decision to cancel the directive without public consultation was justified by the Office of Best Practice Regulation, which determined that such ADs do not necessitate a Regulatory Impact Statement.

Scope and Application

The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of airworthiness directives (ADs) in Australia. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products in accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are essential for ensuring the continuing airworthiness of aircraft and aeronautical products, and they are recognised as legislative instruments under the Legislative Instruments Act 2003. The application of these regulations extends to all aircraft registered in Australia, and CASA, as the State of Registry, has the responsibility to ensure compliance with international standards set forth by the Convention on International Civil Aviation, particularly Annex 8. The geographic reach of these regulations is national, applying uniformly across all Australian states and territories. Notably, while ADs play a critical role in maintaining safety standards, their issuance and cancellation, such as the recent cancellation of AD/TB10/13 for SOCATA TB10 aircraft, are influenced by international obligations and do not necessarily require public consultation or a Regulatory Impact Statement, reflecting the specific nature of their regulatory impact.

Key Provisions

The Civil Aviation Act 1988, specifically section 98, allows the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are critical for maintaining the safety standards of aircraft and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. The State of Design, as per Annex 8 of the Convention on International Civil Aviation, bears the primary responsibility for the continuing airworthiness of an aircraft type and must furnish necessary information to the States of Registry. The State of Registry, in turn, must establish or adopt requirements to ensure the continuing airworthiness of aircraft under its jurisdiction. Under the Civil Aviation Safety Regulations 1998, CASA is mandated to issue ADs to maintain the safety of aircraft in Australian airspace. The cancellation of an AD, such as AD/TB10/13 affecting SOCATA TB10 aircraft, follows a thorough review process and reflects Australia's commitment to international aviation safety standards. The cancellation of AD/TB10/13, which will become effective on 2 July 2009, signifies that no further action is required by CASA, as no replacement AD is necessary. The decision to cancel this AD was made in accordance with Australia's obligations under the Convention on International Civil Aviation and did not require consultation with the Australian public. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The obligations imposed on CASA under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. CASA must ensure that ADs are issued to maintain and improve the safety of aircraft. When CASA cancels an AD, it must do so in compliance with international obligations and in consultation with relevant stakeholders. The Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, has the authority to make such decisions under subsection 84A(2) of the Act. Failure to comply with these regulations can lead to serious consequences, including potential civil or criminal liabilities. The specific penalties for breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are not detailed in the provided text, but they may include fines and other penalties as prescribed by law.
