AD/CESSNA 180/40 Amdt 1 - Main Gear Wheel Assemblies - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation and operations. The Act empowers the Governor-General to create regulations in the interest of air navigation safety, and the Civil Aviation Safety Regulations 1998 further detail the requirements for maintaining aircraft airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The ADs serve as legislative instruments, designed to maintain and ensure the continuing airworthiness of aircraft as per international standards set by the International Civil Aviation Organization (ICAO). The Act's policy objective is to facilitate safe and efficient air navigation by imposing necessary regulatory measures on aircraft airworthiness, thus protecting public safety and aligning with international civil aviation conventions.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, under which airworthiness directives (ADs) are issued, apply to aircraft and aeronautical products within the Australian jurisdiction. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue these directives for specific types of aircraft and aeronautical products. The issuance of ADs is a legislative instrument under the Acts Interpretation Act 1901, and such directives are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, including CASA in Australia, is responsible for ensuring the airworthiness of individual aircraft, including the implementation of ADs issued by the State of Design. The geographic scope of these regulations is national, covering all aircraft registered in Australia and adhering to international standards set by ICAO. While no specific exclusions or exemptions are mentioned in the text, the application of ADs is contingent upon the assessment and approval by CASA, ensuring compliance with both national and international safety standards.

Key Provisions

The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to enact regulations that pertain to the safety of air navigation. Under this section, the Civil Aviation Safety Regulations 1998, regulation 39.001, permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. It is important to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and thus fall under the category of legislative instruments as defined in section 6 of the Legislative Instruments Act 2003. These airworthiness directives are essential in ensuring that the continuing airworthiness of aircraft types is maintained in line with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design is primarily responsible for the ongoing airworthiness of an aircraft type and must provide necessary information to other States of Registry. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft by developing or adopting relevant requirements. When an AD is issued by a State of Design against a type of aircraft registered in Australia, CASA must evaluate this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. In a specific instance, CASA issued AD/CESSNA 180/40 Amendment 1 in 1974, affecting Cessna 180 model aircraft. After reviewing this directive, CASA decided to cancel it, with the cancellation becoming effective on 3 July 2008. This cancellation does not necessitate a replacement AD, as all affected aircraft would have been modified long ago. No consultation with the Australian public was required for this cancellation, as it results in a reduction of the regulatory burden, and the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement. The AD was made by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Under the Civil Aviation Safety Regulations 1998, there are specific obligations and requirements imposed on the parties governed by the Act. CASA, as the national airworthiness authority, must assess any ADs issued by States of Design and determine if Australian ADs are necessary to enforce these directives. The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. Furthermore, aircraft owners and operators must comply with all ADs issued for their specific aircraft types, ensuring that any required modifications or inspections are completed within the specified timeframes. The Act also outlines various offences, penalties, and consequences for breaches of its provisions. Under section 319 of the Civil Aviation Act 1988, any person who contravenes an AD can be issued with a compliance direction or an enforcement direction by CASA. Failure to comply with these directions can result in a civil penalty of up to $111,100 for individuals and $555,500 for corporations, as per section 320. Additionally, CASA has the authority to prosecute serious breaches of the Act, which can lead to criminal penalties, including fines of up to $222,200 for individuals and $1,111,000 for corporations, as well as imprisonment for up to five years, as stipulated in section 323. Furthermore, CASA can also take action to suspend or revoke an aircraft's certificate of airworthiness, effectively grounding the aircraft until the non-compliance issues are resolved.
