AD/SM-205/19 - Carburettor Air Intake Box and Engine Cowling - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, is a comprehensive piece of legislation designed to ensure the safety and efficiency of civil aviation in Australia. The Act provides the legal framework for the regulation of civil aviation, including the issuance of airworthiness directives, which are crucial for maintaining the safety of aircraft and aeronautical products. One of the key objectives of the Act is to align Australian civil aviation practices with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 further elaborate on the mechanisms for ensuring airworthiness, including the process for issuing and managing airworthiness directives. The authority to issue these directives is granted to the Civil Aviation Safety Authority (CASA), which operates under the auspices of the Act to safeguard the public by regulating the safety and efficiency of civil aviation. The cancellation of Airworthiness Directive AD/SM-205/19 affecting SIAI Marchetti S205-22/R and S208 series aeroplanes by CASA on 2 July 2009 exemplifies the dynamic nature of airworthiness regulation. CASA assessed the original directive and determined that the unsafe condition it was addressing no longer existed, leading to the directive's cancellation. This action was taken in accordance with Australia’s obligations under the Convention on International Civil Aviation and did not require public consultation as it was not subject to the requirements of a Regulatory Impact Statement. The cancellation was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in line with the provisions of the Civil Aviation Act 1988.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), Australia’s national airworthiness authority. According to section 98 of the Act, the Governor-General may make regulations in the interest of air navigation safety, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA can issue ADs for specific types of aircraft or aeronautical products. An AD is a legislative instrument that is disallowable under section 46A of the Acts Interpretation Act 1901, and thus subject to the Legislative Instruments Act 2003. These ADs are issued in compliance with Annex 8 to the Convention on International Civil Aviation, where the State of Design has the responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the continuing airworthiness of individual aircraft. CASA must assess information from the State of Design and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. This regulatory framework applies to all entities involved in the design, manufacture, and operation of aircraft within Australia, ensuring that safety standards are met and maintained across the industry.

Key Provisions

The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 that pertain to the issuance of airworthiness directives (ADs) are sections 98 and 39.001 respectively (Civil Aviation Act 1988, s 98; Civil Aviation Safety Regulations 1998, reg 39.001). Section 98 allows the Governor-General to create regulations for the purposes of the Act and the safety of air navigation, while regulation 39.001 provides that CASA may issue ADs for kinds of aircraft or aeronautical products. These regulations are consistent with international standards set out in Annex 8 to the Convention on International Civil Aviation, which establishes the responsibilities of the State of Design and the State of Registry in ensuring the continuing airworthiness of an aircraft type. In practical terms, the State of Design is responsible for providing necessary information to ensure airworthiness, while the State of Registry must implement these requirements for individual aircraft. The obligations imposed by the Act and Regulations on the parties and entities they govern include the State of Design's duty to provide continuing airworthiness information, and the State of Registry's responsibility to develop or adopt requirements to ensure airworthiness. Specifically, CASA, as Australia's national airworthiness authority, must assess any AD issued by the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This ensures that all aircraft registered in Australia comply with the necessary safety standards. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, and no consultation with the Australian public has taken place on this AD cancellation, given Australia's obligations under the Convention on International Civil Aviation. Failure to comply with the provisions of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998, including the issuance and enforcement of ADs, may result in various civil and criminal consequences. While the specific offences, penalties, or consequences are not detailed in the text, it is clear that non-compliance could lead to enforcement actions by CASA. These may include fines, suspension or revocation of airworthiness certificates, or other regulatory actions as deemed necessary to ensure compliance with the safety standards. The maximum penalties for such offences would depend on the specific breach and the relevant provisions of the Act or Regulations, which could range from fines to imprisonment depending on the severity of the offence.
