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-31/3 affecting Piper PA-31 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, provides the legislative framework for ensuring the safety of air navigation in Australia. In accordance with this Act, 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. These ADs are critical for maintaining the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The recent cancellation of AD/PA-31/3, which affected Piper PA-31 aircraft, reflects CASA’s commitment to adhering to international standards and ensuring that ADs are issued only when necessary. This cancellation, effective from 31 July 2008, was made without public consultation, as it aligns with international obligations and does not require a Regulatory Impact Statement. The decision was executed by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, ensuring compliance with the legislative requirements outlined in the Act.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish a framework for ensuring the safety of air navigation in Australia. Specifically, under section 98 of the Civil Aviation Act 1988, the Governor-General can make regulations in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. These airworthiness directives are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry have specific responsibilities. The recent cancellation of AD/PA-31/3, affecting Piper PA-31 aircraft, by CASA reflects Australia's adherence to international obligations, with no replacement AD deemed necessary. The cancellation process, overseen by the Manager, Airframes in the Airworthiness Engineering Branch at CASA, complies with subsection 84A(2) of the Act and has not required public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products (section 98 and regulation 39.001). These directives are crucial for ensuring the safety and airworthiness of aircraft operating within Australia. Notably, an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and as such, it is classified as a legislative instrument according to the Legislative Instruments Act 2003 (subregulation 39.001(5)).
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to issue ADs when necessary to maintain the safety and airworthiness of aircraft. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type under Annex 8 of the Convention on International Civil Aviation, which includes providing necessary information to States of Registry. Conversely, the State of Registry, which in this context is Australia, must establish or adopt requirements to ensure the continuing airworthiness of individual aircraft (Annex 8). CASA, as the regulatory body in Australia, has historically issued directives such as AD/PA-31/3 for Piper PA-31 aircraft, although this specific directive has since been cancelled.
In terms of consequences, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail offences or penalties for non-compliance with ADs. However, failure to adhere to these directives could potentially lead to significant safety risks and could result in enforcement actions by CASA, including the suspension or revocation of an aircraft's certificate of airworthiness. The civil or criminal consequences for such failures would depend on the specific circumstances and the severity of the non-compliance. Given that ADs are integral to maintaining aviation safety, non-compliance could also result in severe operational disruptions or accidents, with associated legal and financial liabilities.
