AD/PA-23/59 - Wing Rear Spar - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to regulate civil aviation within the country and ensure the safety of air navigation. This Act empowers the Governor-General to make regulations for the Act's purposes and in the interests of safety. Specifically, the Civil Aviation Safety Regulations 1998 were made under this Act, and regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. This regulatory framework is designed to address gaps in ensuring the ongoing safety and airworthiness of aircraft by aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation, where the State of Design and State of Registry hold responsibilities for the continuing airworthiness of aircraft types. The cancellation of AD/PA-23/59, which affected Piper PA-23 and PA-23-160 aircraft, by CASA illustrates the application of these regulations. The cancellation was enacted due to Australia’s obligations under the Convention on International Civil Aviation and will become effective on 12 February 2009. This action was taken without public consultation as determined by the Office of Best Practice Regulation, which concluded that ADs do not require a Regulatory Impact Statement. The AD was issued by the acting Manager, Airframes and Structures in the Airworthiness Engineering Group at CASA, in accordance with the provisions of the Act.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively govern the issuance and implementation of airworthiness directives (ADs) in Australia, ensuring the ongoing safety of aircraft and aeronautical products. Under these legislative instruments, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific types of aircraft or aeronautical products to maintain their airworthiness, and these directives are considered legislative instruments. The geographic reach of this legislation extends to the entire Commonwealth of Australia, encompassing both domestic and international aviation activities that fall under Australian regulatory oversight. The Civil Aviation Act 1988 and its associated regulations are consistent with international standards set by the International Civil Aviation Organization (ICAO), particularly Annex 8, which mandates that the State of Design is responsible for the continuing airworthiness of aircraft types, while the State of Registry is responsible for individual aircraft. This legislation applies to aircraft operators, manufacturers, and other entities involved in the aviation industry within Australia. While the ADs themselves are legislative instruments that are subject to disallowance and scrutiny under Australian law, the specific process of issuing these directives and their content is guided by international obligations and domestic safety standards.

Key Provisions

Under the Civil Aviation Act 1988, the Governor-General has the authority to create regulations aimed at enhancing the safety of air navigation (section 98). These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. According to subregulation 39.001(5), ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. The Civil Aviation Safety Regulations 1998 mandate CASA to issue ADs to ensure the continuing airworthiness of aircraft, aligning with the State of Design's responsibility under Annex 8 of the Convention on International Civil Aviation. This convention also places the responsibility of an individual aircraft's continuing airworthiness on the State of Registry, which must establish or adopt requisite measures to uphold the aircraft's airworthiness. An example of this regulatory framework in action is CASA's issuance of AD/PA-23/59 for Piper PA-23 and PA-23-160 aircraft, which has now been reviewed and cancelled by CASA, effective 12 February 2009. No replacement AD is deemed necessary following this cancellation. The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include ensuring the continuing airworthiness of aircraft types and individual aircraft. The State of Design must provide necessary information to States of Registry, who are then responsible for implementing airworthiness directives. CASA's role involves reviewing and, when necessary, cancelling ADs, as seen in the case of AD/PA-23/59. Given Australia's commitments under the Convention on International Civil Aviation, no public consultation or Regulatory Impact Statement was required for the cancellation of this specific AD. In terms of consequences, breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in both civil and criminal penalties. The exact penalties are not detailed in the provided text, but they generally include fines and, in severe cases, imprisonment. The enforcement of these regulations ensures that all parties adhere to the mandated safety standards, thereby maintaining the integrity of the aviation safety framework in Australia.
