AD/CESSNA 185/1 Amdt 3 - Plastic Control Wheel

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, serves to regulate civil aviation in Australia with a primary focus on ensuring the safety of air navigation. This Act provides the legislative framework for the creation of regulations that contribute to the overarching goal of maintaining safe air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail specific safety requirements and procedures, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The ADs, which are legislative instruments, are essential tools for maintaining the continuing airworthiness of aircraft as mandated by international agreements such as Annex 8 to the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, is responsible for issuing ADs that reflect international standards and address safety concerns specific to aircraft registered in Australia. This legislative framework ensures that safety standards are consistently applied across the aviation industry, protecting both the public and the interests of the state.

Scope and Application

The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, specifically under regulation 39.001. The Act empowers the Governor-General to enact regulations in the interests of air navigation safety, and under this authority, the Civil Aviation Safety Authority (CASA) is mandated to issue ADs for particular types of aircraft or aeronautical products. These ADs, which are legislative instruments, are designed to ensure the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry. In Australia, CASA assumes the role of the national airworthiness authority, obligated to evaluate information from the State of Design and, where necessary, issue Australian ADs that enforce the State of Design's requirements. This legislative framework ensures that Australian-registered aircraft meet international safety standards, with ADs serving as a critical mechanism for maintaining airworthiness, as exemplified by the recent amendment to AD/CESSNA 185/1 Amendment 2 concerning Cessna 185 model aircraft. The amendment, effective from 30 July 2009, eliminates reference to an outdated service letter, streamlining the regulatory requirements for Australian industry.

Key Provisions

The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations that contribute to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is a disallowable instrument, as defined by section 46A of the Acts Interpretation Act 1901, and is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003. This framework ensures that ADs are issued to maintain and improve the safety standards of aviation. The obligations imposed by these regulations include the State of Design, which, under Annex 8 to the Convention on International Civil Aviation, is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to appropriate States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft. When an AD is issued by the State of Design, CASA, as Australia's national airworthiness authority, must review this information and, if necessary, issue an Australian AD to enforce the requirements. This ensures that Australian aircraft meet the safety standards set forth by international conventions. In the case of AD/CESSNA 185/1 Amendment 2, CASA issued this directive to address cracks in the plastic control wheels of Cessna 185 model aircraft manufactured in 1969. After reviewing the directive, CASA has amended it to remove reference to an outdated Cessna Service Letter. AD/CESSNA 185/1 Amendment 3 will become effective on 30 July 2009, replacing the previous issue. CASA did not consult with the Australian industry and public for this amendment as it reduces the regulatory burden on the industry. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The consequences for non-compliance with these regulations can be severe. The AD has been made by the Manager, Airframes and Structures on behalf of CASA, in accordance with subsection 84A(2) of the Act. Failure to adhere to the requirements set forth in ADs can result in civil and criminal penalties. While the specific penalties are not detailed in the provided text, breaches of aviation safety regulations can lead to significant fines, operational restrictions, or even criminal charges depending on the severity of the non-compliance.
