CIVIL AVIATION ACT 1988

CIVIL AVIATION SAFETY REGULATIONS 1998

ISSUE OF AIRWORTHINESS DIRECTIVE

Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation.  Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products.  Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.

Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry.  ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.

The State of Registry of an individual aircraft is responsible for its continuing airworthiness.  Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft.

CASA or its predecessors issued AD/PA-25/2 Amdt 1 affecting Piper PA-25 aircraft.  CASA has reviewed this AD and as a result has cancelled it.  The cancellation will become effective on 20 November 2008.  No replacement AD is required.

As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation.  The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.

 

The AD has been made by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.

Overview

The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation within Australia, with the Civil Aviation Safety Regulations 1998 providing further detail on implementing this objective. This Act allows the Governor-General to make regulations for the Act's purposes, with regulation 39.001 empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft types and aeronautical products. These ADs serve as a legislative instrument, consistent with section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The ADs are a reflection of Australia’s commitment to international standards, particularly under Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to ensure the continuing airworthiness of aircraft types and requires States of Registry to maintain these standards. CASA, acting under these international obligations, has the responsibility to ensure the continuing airworthiness of aircraft registered in Australia.

Scope and Application

The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are integral to ensuring the safety of air navigation, and they serve as a legislative instrument under section 6 of the Legislative Instruments Act 2003. The scope of these regulations extends to all aircraft registered in Australia, as the State of Registry bears the responsibility for the continuing airworthiness of each aircraft. The ADs are aligned with Annex 8 to the Convention on International Civil Aviation, which stipulates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type. Although the ADs themselves do not necessitate a Regulatory Impact Statement or public consultation, they play a crucial role in maintaining safety standards in civil aviation within Australia.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance and management of airworthiness directives (ADs) in Australia, as well as the cancellation of such directives when necessary. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that pertain to the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. The authority to issue ADs is critical for maintaining the safety and airworthiness of aircraft in Australian airspace. The obligations placed on CASA under the Civil Aviation Safety Regulations 1998 include the responsibility to ensure that ADs are issued when necessary to address safety concerns. Additionally, CASA must review and, if necessary, cancel ADs when it is determined that the safety issue they were intended to address has been adequately resolved. The obligation to issue ADs is guided by international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and requires that appropriate information be provided to States of Registry. The State of Registry, in turn, must ensure that its aircraft remain airworthy, which involves implementing the requirements set out in the ADs. Failure to comply with ADs or other regulations set forth under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant legal consequences. While the specific offences and penalties for non-compliance with ADs are not detailed in the given text, generally, violations of civil aviation regulations can lead to both criminal and civil liabilities. Criminal penalties may include fines and imprisonment, while civil penalties can include substantial fines and enforcement actions against the non-compliant party. The exact penalties are determined by the severity of the breach and the specific provisions of the regulations that have been violated. It is crucial for all stakeholders, including aircraft operators and owners, to adhere to the ADs issued by CASA to avoid these potential consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, along with the international standards set by the Convention on International Civil Aviation, establish a comprehensive framework for the regulation of airworthiness directives in Australia. CASA's role in issuing, reviewing, and cancelling ADs is fundamental to maintaining the safety and reliability of the national airspace. Compliance with these regulations is mandatory for all parties involved in civil aviation, and failure to do so can result in severe penalties. The legislative framework ensures that the highest safety standards are upheld, protecting the public and maintaining the integrity of the aviation industry.
