AD/PA-31/61 - Elevator Bell Crank and Control Rod - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, governs civil aviation in Australia with a primary focus on ensuring safety within air navigation. One of its key provisions allows the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, to achieve this objective. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments designed to maintain the continuing airworthiness of aircraft and aeronautical products. In line with international obligations under Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for providing necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry is tasked with implementing and enforcing these requirements. The cancellation of a specific airworthiness directive affecting Piper PA-31 aircraft, as decided by CASA, exemplifies the authority's role in upholding these safety standards, reflecting Australia's commitment to international civil aviation obligations.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These directives are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and subject to the Legislative Instruments Act 2003. ADs are a common mechanism for maintaining the continuing airworthiness of aircraft types, as mandated by Annex 8 of the Convention on International Civil Aviation. The State of Design is responsible for the overall continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, ensures the individual aircraft's continuing airworthiness. CASA's Manager, Airframes, in the Airworthiness Engineering Branch, has the authority to issue such directives on behalf of CASA under subsection 84A(2) of the Act. The cancellation of AD/PA-31/61 for Piper PA-31 aircraft, effective from 31 July 2008, is due to Australia’s obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement was required for this cancellation.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations aimed at enhancing the safety of air navigation. Under this authority, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This legislative framework ensures that safety measures are consistently applied across the aviation industry to maintain high standards of airworthiness. An airworthiness directive, as stipulated in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901. Consequently, it falls under the category of legislative instruments as defined in section 6 of the Legislative Instruments Act 2003. This classification underscores the importance of ADs in regulating the continuing airworthiness of aircraft and aeronautical products, ensuring compliance with international standards set by the Convention on International Civil Aviation, particularly under Annex 8. In accordance with Annex 8, the State of Design bears the primary responsibility for the continuing airworthiness of an aircraft type, and must furnish any necessary information to the appropriate States of Registry. This information is vital for maintaining the airworthiness of aircraft types globally. The State of Registry, in turn, is tasked with developing or adopting requirements to ensure the continuing airworthiness of individual aircraft. This collaborative approach ensures that safety standards are uniformly applied and enforced across different jurisdictions. The obligations imposed by these regulations extend to CASA, which has the authority to issue ADs to address safety concerns. For example, CASA has issued and subsequently cancelled AD/PA-31/61 concerning Piper PA-31 aircraft. This cancellation, effective from 31 July 2008, was made in accordance with Australia’s international obligations under the Convention on International Civil Aviation, and no replacement AD is required. The process for cancelling such an AD does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. In terms of legal consequences, any breach of the provisions outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 may result in various penalties. The specific nature and severity of these penalties can vary depending on the nature of the breach and the relevant sections of the Act. However, the maximum penalties for such breaches are not detailed in the provided text, and would need to be sought in the full text of the legislation.
