AD/CESSNA 337/10 - Front Seat Restraint Installations - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, governs the safety and regulation of civil aviation within Australia. This Act provides the legislative framework for ensuring that civil aviation activities are conducted safely and efficiently. One of the significant mechanisms within this framework is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs to mandate safety requirements for specific types of aircraft or aeronautical products. The policy objective behind the Civil Aviation Act 1988 is to maintain and enhance the safety of air navigation, which is further supported by the international standards set by the Convention on International Civil Aviation. The cancellation of AD/CESSNA 337/10, which was issued by CASA in 1971, reflects the continuous efforts to refine and update safety regulations in response to new information and changing conditions. This cancellation, effective from 17 January 2008, was made by the Manager, Airframes in the Airworthiness Engineering Branch of CASA, in line with the legislative requirements of the Act.

Scope and Application

The Civil Aviation Act 1988 provides the legislative framework under which the Civil Aviation Safety Regulations 1998 operate, and it encompasses various aspects of air navigation safety. Under this Act, the Governor-General has the authority to make regulations that promote the safety of air navigation, with one such regulation being the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs, which are legislative instruments, are issued to ensure the continuing airworthiness of aircraft types or aeronautical products. These directives are crucial for maintaining safety standards in compliance with international conventions such as Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is responsible for assessing and issuing ADs based on information from the State of Design, ensuring that the continuing airworthiness of aircraft registered in Australia is upheld. The application of these regulations extends to all aircraft registered in Australia, and their scope is further detailed and potentially expanded through subordinate instruments, which adhere to the requirements and guidelines set forth by the overarching Act and its associated regulations.

Key Provisions

The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations for the Act's purposes, particularly in relation to the safety of air navigation. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus, an AD qualifies as a legislative instrument under section 6 of the Legislative Instruments Act 2003. These airworthiness directives are critical for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which is the country where the aircraft type is designed, has the overarching responsibility for ensuring the continuing airworthiness of the aircraft type and must provide necessary information to the States of Registry. Conversely, the State of Registry, which is the country where the aircraft is registered, must establish or adopt requirements to ensure the continuing airworthiness of individual aircraft. In Australia, CASA, as the national airworthiness authority, is tasked with assessing information from the State of Design and, if necessary, issuing an Australian AD to enforce the State of Design's requirements on aircraft registered in Australia. CASA issued AD/CESSNA 337/10 in 1971, affecting Cessna 337 model aircraft. After a review, CASA has decided to cancel this directive, effective 17 January 2008. This cancellation does not necessitate a replacement AD, as the original safety concern has been addressed by AD/GENERAL/74 Amendment 1. The cancellation of this AD was not subject to consultation with the Australian public, as it reduces the regulatory burden, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. The Act outlines obligations for CASA to ensure that airworthiness directives are issued and managed in a manner that promotes the safety of air navigation. Any failure to comply with the requirements set forth in these regulations may result in civil or criminal consequences, including potential penalties for non-compliance with the ADs, although specific penalties are not detailed in this context.
