AD/PA-34/16 Amdt 1 - Wing Spar Lower Tension Strap - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide a legal framework for the safety and regulation of civil aviation in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations to ensure the safety of air navigation. Complementing this, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products through regulation 39.001. The ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. These directives are essential for ensuring the continuing airworthiness of aircraft types, in line with Australia's obligations under Annex 8 of the Convention on International Civil Aviation, which places responsibility for this on the State of Design and the State of Registry. The Civil Aviation Safety Authority has the authority to issue and, as necessary, cancel these directives to maintain safety standards without the need for public consultation or a Regulatory Impact Statement.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively govern the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) being the regulatory body responsible for ensuring the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products to maintain airworthiness. These ADs are legislative instruments and must comply with the requirements of the Legislative Instruments Act 2003. The ADs serve to ensure compliance with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry of an aircraft. The AD in question, AD/PA-34/16 Amdt 1, which affected Piper PA-34 aircraft, was issued by CASA but has since been cancelled due to Australia's obligations under the Convention. This cancellation took effect on 23 October 2008, and no replacement AD is required. Given the international nature of these obligations, no public consultation was deemed necessary, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The cancellation of the AD was authorised by the Manager, Airframes in the Airworthiness Engineering Group, on behalf of CASA, in accordance with the Act.

Key Provisions

The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products (section 39.001(5)). These directives serve as a legislative instrument to ensure the safety of air navigation, as per section 98 of the Civil Aviation Act 1988. It is important to note that the issuance of an AD falls under the purview of Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type. Correspondingly, the State of Registry, which in this context is Australia, has the responsibility to ensure the continuing airworthiness of individual aircraft by developing or adopting necessary requirements. The obligations placed on parties by this Act include the State of Design’s responsibility to provide any information necessary to maintain the continuing airworthiness of an aircraft type to the appropriate States of Registry, as stipulated in Annex 8. Similarly, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. CASA, as the regulatory authority in Australia, is mandated to issue ADs to fulfil these obligations and to ensure compliance with international aviation safety standards. The process of issuing and cancelling ADs must also align with Australia's obligations under the Convention on International Civil Aviation, ensuring that all actions taken are in accordance with international norms and standards. The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 do not explicitly outline specific offences, penalties, or consequences for non-compliance with ADs. However, non-compliance with ADs can have severe implications under broader aviation safety laws and regulations. Failure to comply with ADs may result in the grounding of aircraft, revocation of airworthiness certificates, and legal action against the aircraft operator. Furthermore, significant penalties, including fines and imprisonment, may be imposed under other sections of the Civil Aviation Act 1988 for endangering the safety of an aircraft or for operating an aircraft that is not airworthy. The Civil Aviation Safety Authority has the authority to enforce compliance and take necessary actions to address breaches, ensuring that all aircraft within Australia's jurisdiction meet the required safety standards.
