AD/CESSNA 180/2 - Right Wing Rear Spar - CANCELLED

Overview

The Civil Aviation Act 1988, enacted to ensure the safety of air navigation, empowers the Governor-General to make regulations under section 98, which includes the issuance of airworthiness directives (ADs). These directives, governed by regulation 39.001 of the Civil Aviation Safety Regulations 1998, are legislative instruments as per section 46A of the Acts Interpretation Act 1901. The ADs serve as a crucial mechanism for ensuring the continuing airworthiness of aircraft, aligning with Annex 8 of the Convention on International Civil Aviation. This Act mandates that the State of Registry, in this case CASA, must assess and implement necessary ADs issued by the State of Design, ensuring compliance with international standards. In a specific instance, CASA has decided to cancel AD/CESSNA 180/2, which affected Cessna 180 model aircraft in 1967. The cancellation, effective from 3 July 2008, is due to the conclusion that all affected aircraft have been modified, thus rendering the directive unnecessary. The decision to cancel 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. This action aligns with the policy objective of reducing regulatory burden, and as determined by the Office of Best Practice Regulation, it does not require a Regulatory Impact Statement.

Scope and Application

The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, applies to the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. The ADs are legislative instruments under the Legislative Instruments Act 2003 and are designed to maintain the continuing airworthiness of aircraft in accordance with international standards set by the International Civil Aviation Organization (ICAO). The State of Design and the State of Registry bear responsibilities under Annex 8 of the Convention on International Civil Aviation for providing necessary information and ensuring airworthiness respectively. The cancellation of AD/CESSNA 180/2, affecting Cessna 180 model aircraft from 1967, exemplifies CASA's role in assessing and implementing ADs, with the decision to cancel this particular directive based on the understanding that all affected aircraft have already been modified. This cancellation, which reduces the regulatory burden, did not require public consultation or a Regulatory Impact Statement. The authority to issue such directives is exercised by CASA under the Civil Aviation Act 1988, specifically as authorised by the Manager, Airframes in the Airworthiness Engineering Branch.

Key Provisions

The Civil Aviation Act 1988 provides a framework for the regulation of civil aviation in Australia, with key provisions enabling the Governor-General to make regulations in the interests of safety (section 98). Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, detailed in subregulation 39.001(5), are considered disallowable instruments under the Acts Interpretation Act 1901 and are legislative instruments as per the Legislative Instruments Act 2003. This means ADs have the force of law and must be adhered to by the relevant parties. The obligations imposed by the Civil Aviation Safety Regulations 1998 and the ADs themselves are primarily concerned with maintaining the airworthiness of aircraft. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure ongoing airworthiness. Under Annex 8 of the Convention on International Civil Aviation, the State of Design must share relevant information with States of Registry, which in turn are required to implement the necessary requirements to ensure the continuing airworthiness of the aircraft registered within their jurisdiction. In Australia, CASA, as the national airworthiness authority, must review any ADs issued by States of Design and, if appropriate, issue Australian ADs that mandate the requirements. The Civil Aviation Safety Regulations 1998 also detail the consequences of non-compliance with ADs. Failure to adhere to the requirements set out in an AD can result in serious safety implications, as these directives are designed to address known safety issues with aircraft. Although the specific offences and penalties are not detailed in the text provided, it is understood that non-compliance with ADs can lead to severe civil or criminal penalties, reflecting the critical nature of maintaining airworthiness. The regulatory framework ensures that all stakeholders, including aircraft operators and manufacturers, are held to high safety standards to protect the public and ensure the safe operation of aircraft. The text notes that CASA issued an AD affecting Cessna 180 model aircraft in 1967 and has since decided to cancel this directive. The cancellation of AD/CESSNA 180/2, effective from 3 July 2008, is due to the fact that all affected aircraft have been modified long ago, thus eliminating the need for ongoing regulatory oversight. No public consultation was required for this cancellation as it results in a reduction of regulatory burden. The Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement, further streamlining the process. The AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
