AD/BEECH 55/53 - Engine Firewall Elbow Fitting - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, including the safety of air navigation. The Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. The ADs are crucial in maintaining the continuing airworthiness of aircraft, as required under Annex 8 to the Convention on International Civil Aviation. CASA issued an AD/BEECH 55/53 for Beechcraft 58P and 58PA model aircraft, but subsequently cancelled it on 5 June 2008, as the unsafe condition no longer existed. This action was taken in line with Australia's obligations under the Convention on International Civil Aviation, without the need for a Regulatory Impact Statement or public consultation. The AD cancellation was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the provisions of the Civil Aviation Act 1988.

Scope and Application

The Civil Aviation Act 1988, as supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which are regulatory instruments aimed at ensuring the safety of air navigation. These directives apply to specific types of aircraft or aeronautical products and are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA as Australia's national airworthiness authority, must ensure that these directives are assessed and, if necessary, adopted to maintain airworthiness standards. ADs are legislative instruments that are subject to disallowance and reporting requirements under the Legislative Instruments Act 2003. The scope of these regulations extends to all aircraft registered in Australia, encompassing both domestic and international operations. However, no public consultation or Regulatory Impact Statement is required for ADs, as determined by the Office of Best Practice Regulation. The AD/BEECH 55/53, which affected Beechcraft 58P and 58PA model aircraft, has been cancelled by CASA due to the resolution of the unsafe condition, effective from 5 June 2008, without the need for a replacement directive.

Key Provisions

The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs). Section 98 of the Act empowers the Governor-General to create regulations in the interest of air navigation safety, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Section 39.001(5) further clarifies that ADs are legislative instruments, as they fall under the purview of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The obligations imposed by the Civil Aviation Safety Regulations 1998 on the parties concerned are significant. The State of Design, which is the country where the aircraft type was designed, holds the primary responsibility for ensuring the ongoing airworthiness of the aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to ensure the continuing airworthiness of the type to appropriate States of Registry. On the other hand, the State of Registry is tasked with developing or adopting requirements to maintain the continuing airworthiness of the aircraft within its jurisdiction. CASA, as Australia’s national airworthiness authority, must assess any ADs issued by the State of Design and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. In terms of consequences for non-compliance, the Act and Regulations do not explicitly state penalties for failing to adhere to ADs. However, the serious nature of airworthiness and the overarching objective of ensuring safety imply that non-compliance could lead to severe repercussions, including potential grounding of the aircraft, legal action, or other civil or criminal penalties. Although the specific penalties are not detailed in the text, the implications of compromising on airworthiness are inherently grave, given the life-threatening nature of aviation safety. The text also addresses the cancellation of AD/BEECH 55/53, which affected Beechcraft 58P and 58PA model aircraft. CASA assessed this AD and determined that it should be cancelled as the unsafe condition it addressed no longer exists. This cancellation, which will become effective on 5 June 2008, means no replacement AD is necessary. Furthermore, since this cancellation aligns with Australia’s obligations under the Convention on International Civil Aviation, no public consultation was necessary, and the Office of Best Practice Regulation has determined that a Regulatory Impact Statement is not required. The Manager, Systems and New Technologies in the Airworthiness Engineering Branch made this AD on behalf of CASA, in accordance with subsection 84A(2) of the Act.
