AD/CESSNA 400/4 - Engine Support Beam - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted to ensure the safety of air navigation, empowers the Governor-General to create regulations for the Act's purposes, with the Civil Aviation Safety Regulations 1998 being a key instrument. Under this Act, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for types of aircraft or aeronautical products as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is a disallowable instrument under the Acts Interpretation Act 1901 and constitutes a legislative instrument according to the Legislative Instruments Act 2003. The AD/CESSNA 400/4, affecting Cessna 411 model aircraft, issued by CASA or its predecessors, has been cancelled by CASA effective 28 August 2008 due to Australia's obligations under the Convention on International Civil Aviation. The cancellation aligns with Annex 8, which places the responsibility for continuing airworthiness of an aircraft type on the State of Design and requires the State of Registry to ensure the continuing airworthiness of individual aircraft. No consultation with the public or a Regulatory Impact Statement was required for this AD cancellation, as determined by the Office of Best Practice Regulation. The AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.

Scope and Application

The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 apply to all aircraft and aeronautical products in Australia, encompassing entities such as aircraft manufacturers, operators, and maintenance organisations, as well as individual pilots and engineers. The regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments designed to ensure the safety of air navigation. The scope of these regulations is broad, extending to all types of aircraft within Australian jurisdiction, and they align with international standards set by the International Civil Aviation Organization (ICAO). Specifically, under the Act and the Regulations, CASA has the authority to issue and cancel ADs, such as AD/CESSNA 400/4, which was recently cancelled for Cessna 411 model aircraft. The jurisdictional reach of these regulations is national, applying uniformly across all states and territories of Australia. Notably, the issuance of ADs does not require consultation with the Australian public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs reflect Australia's commitment to international standards, particularly under the Convention on International Civil Aviation, where the State of Design and the State of Registry play critical roles in maintaining the continuing airworthiness of aircraft.

Key Provisions

The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to make regulations to ensure the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD, as per subregulation 39.001(5), is considered a disallowable instrument under the Acts Interpretation Act 1901 and a legislative instrument under the Legislative Instruments Act 2003. These directives are fundamental for maintaining the continuing airworthiness of aircraft types, in line with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design bears responsibility for the ongoing airworthiness of an aircraft type and must provide necessary information to the State of Registry. Under the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products, ensuring compliance with safety standards. The State of Registry, as outlined in Annex 8, is responsible for ensuring the continuing airworthiness of individual aircraft and must develop or adopt appropriate requirements to this end. A specific example of this regulatory process is AD/CESSNA 400/4, which affected Cessna 411 model aircraft. CASA reviewed this directive and subsequently cancelled it, effective from 28 August 2008, without requiring a replacement directive. This cancellation aligns with Australia’s commitments under the Convention on International Civil Aviation. The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on CASA and the States of Design and Registry include ensuring the continuous airworthiness of aircraft through the issuance and enforcement of ADs. CASA, in its capacity, must review and, when necessary, cancel ADs to maintain safety standards and comply with international obligations. The cancellation of AD/CESSNA 400/4 exemplifies this regulatory action, which has been carried out without public consultation due to the specific nature of ADs and their alignment with international conventions. The Office of Best Practice Regulation has determined that such ADs do not necessitate a Regulatory Impact Statement, reflecting the targeted and specific nature of these legislative instruments. In terms of consequences for non-compliance, while the text does not explicitly detail offences or penalties for breaching ADs, the overarching regulatory framework implies significant implications for failing to comply with airworthiness directives. Such non-compliance could potentially result in severe civil or criminal penalties, reflecting the high stakes involved in aviation safety. The statutory authority under which ADs are issued underscores the importance of adherence to these directives to maintain the safety and integrity of air navigation.
