AD/CESSNA 400/19 - Elevator Torque Tube - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, serves as the fundamental legislation governing civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to create regulations that align with the Act's objectives and the interests of aviation safety. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, include provisions that allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that must comply with the requirements of the Legislative Instruments Act 2003. The overarching goal of these regulations is to ensure the continuing airworthiness of aircraft, aligning with Australia's commitments under the Convention on International Civil Aviation, particularly Annex 8, which delineates the responsibilities of the State of Design and the State of Registry for maintaining aircraft airworthiness. The issuance and cancellation of ADs are critical for maintaining safety standards in Australian civil aviation, with CASA playing a pivotal role in this process. The cancellation of AD/CESSNA 400/19, affecting certain Cessna aircraft models, exemplifies the regulatory framework's responsiveness to international obligations and safety considerations. This particular AD cancellation, made without public consultation due to its alignment with international conventions, highlights the balance between domestic regulatory actions and global aviation standards. The decision to cancel the AD was executed by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA, in accordance with the Civil Aviation Act 1988, reflecting a commitment to maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are legislative instruments that ensure compliance with safety standards and the continuing airworthiness of aircraft. The issuance of these directives is guided by the Convention on International Civil Aviation, where the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry maintains the responsibility for the individual aircraft. CASA, acting on behalf of the Australian government, issued and subsequently cancelled AD/CESSNA 400/19, which pertained to certain Cessna model aircraft. This cancellation, effective from 28 August 2008, aligns with Australia's obligations under international civil aviation agreements and does not necessitate public consultation or a Regulatory Impact Statement. The decision to cancel the directive was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA, in accordance with the Act.

Key Provisions

The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products (section 39.001). An AD is a legislative instrument that falls under the purview of the Legislative Instruments Act 2003 (subsection 39.001(5)). These directives serve as a means of ensuring the continuing airworthiness of aircraft types, aligning with Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for providing necessary information to maintain airworthiness, while the State of Registry must implement and enforce the airworthiness standards for individual aircraft (section 98). Under the Civil Aviation Safety Regulations 1998, CASA is empowered to issue ADs that are enforceable under the Acts Interpretation Act 1901 (section 46A). This regulatory framework mandates that the State of Registry must develop or adopt measures to maintain the airworthiness of aircraft within their jurisdiction (Annex 8). As part of this responsibility, CASA has the capacity to review and cancel existing ADs, such as AD/CESSNA 400/19, which previously governed certain Cessna aircraft models (sections 401, 402, 411, 414, 421). The cancellation of this directive is a result of Australia’s obligations under the Convention on International Civil Aviation and is effective as of 28 August 2008, with no replacement directive required. The process of issuing and cancelling ADs is conducted by CASA, specifically by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, in accordance with the Act (subsection 84A(2)). The cancellation of the AD in question has not required consultation with the Australian public due to the nature of the obligations under the Convention on International Civil Aviation, and it does not necessitate a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. In terms of compliance and enforcement, any breach of the requirements set forth in the ADs may result in civil or criminal consequences, depending on the severity of the violation. The specific penalties for such breaches are not detailed within the text provided but would typically be outlined in the Civil Aviation Act 1988 and associated regulations. The overarching aim of these provisions is to ensure the safety of air navigation and the continued airworthiness of aircraft operating within Australia’s jurisdiction.
