AD/CESSNA 205/24 - Alternate Static Air Source Valve

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, governs the safety and regulation of civil aviation within Australia. The Act was introduced to address the need for comprehensive regulation of air navigation and aircraft safety. Under this Act, the Civil Aviation Safety Regulations 1998 were established to provide further detail on operational safety requirements, including the issuance of airworthiness directives (ADs). These ADs, issued by the Civil Aviation Safety Authority (CASA), serve to ensure the continuing airworthiness of aircraft in response to identified safety issues. The policy objective of the ADs is to comply with international standards as outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that Australia meets its obligations as a Contracting State. The legislative process for issuing ADs involves CASA evaluating safety directives issued by the aircraft's State of Design and, where necessary, issuing corresponding Australian ADs to enforce these safety measures on aircraft registered in Australia. The ADs issued by CASA in response to the United States Federal Aviation Administration's AD 2008-10-02 for various Cessna aircraft series were made under the authority provided by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Given that these directives are in direct response to international obligations, no public consultation was required, and the Office of Best Practice Regulation deemed them not to require a Regulatory Impact Statement. These ADs were issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA.

Scope and Application

The Civil Aviation Safety Regulations 1998, made under section 98 of the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This legislative framework is designed to ensure the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). The State of Design, which is responsible for the overall airworthiness of an aircraft type, issues ADs, and the State of Registry, which is responsible for the airworthiness of individual aircraft, must adopt these requirements. In Australia, CASA acts as the national airworthiness authority and must assess ADs issued by the State of Design, issuing Australian ADs if deemed appropriate. These ADs are considered legislative instruments and are issued in accordance with the Legislative Instruments Act 2003. Given that these ADs are in response to international obligations and are issued by the relevant State of Design, they do not require public consultation or a Regulatory Impact Statement. They are issued by CASA on behalf of the Minister for Infrastructure and Transport.

Key Provisions

The main operative sections of this legislation pertain to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interest of the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are thus legislative instruments. The obligations imposed by the Act and the Regulations require CASA to assess ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. For instance, when the United States Federal Aviation Administration (FAA) issued AD 2008-10-02 affecting various Cessna aircraft series, CASA assessed this directive and issued Australian ADs, as listed in Schedule 1, to be effective from 13 May 2008. These ADs are necessary to meet Australia’s obligations under the Convention on International Civil Aviation. Failure to comply with these ADs can result in significant consequences. Non-compliance with ADs may lead to severe civil or criminal penalties, as stipulated in the Civil Aviation Act 1988 and other related legislation. The specific penalties for breaching airworthiness requirements can include substantial fines and potential imprisonment. For example, under the Civil Aviation Act, a person who contravenes an AD may be subject to a maximum penalty of up to $165,000 or imprisonment for up to two years, or both. Additionally, CASA may take enforcement actions such as grounding affected aircraft until compliance is achieved. The issuing authority for these ADs is clearly defined in the legislation. The ADs are issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act. This ensures that the directives are issued by qualified personnel within the appropriate branch of CASA, maintaining the integrity and authority of the regulatory process.
