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, 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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
CASA issued AD/PW-P/7 affecting Pratt and Whitney piston engines. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective 27 August 2009. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, 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 and efficiency of civil aviation in Australia, with a focus on air navigation and aircraft airworthiness. Under 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 directives serve as a primary mechanism for maintaining the continuing airworthiness of aircraft types, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation. The objective of these regulations is to ensure that the State of Registry, which in Australia is CASA, implements the necessary measures to maintain the airworthiness of registered aircraft. The issuing of ADs by CASA follows a review process, as evidenced by the cancellation of AD/PW-P/7 for Pratt and Whitney piston engines, reflecting the resolution of the original safety concern without the need for a replacement directive. This legislative framework is designed to reduce regulatory burdens and maintain high safety standards in the aviation industry.
Scope and Application
The Civil Aviation Safety Regulations 1998, as authorised by the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs apply to specific types of aircraft or aeronautical products within Australia and mandate certain requirements for maintaining their airworthiness. An AD is considered a legislative instrument under the Legislative Instruments Act 2003, and its issuance aligns with the standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in Australia is CASA, is responsible for ensuring the continuing airworthiness of aircraft registered within its jurisdiction. In the case of Pratt and Whitney piston engines, CASA issued and subsequently cancelled AD/PW-P/7, effective from 27 August 2009, as the original unsafe condition no longer existed, thus reducing regulatory burden. This cancellation did not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Future Technology and Regulatory Trends, within CASA's Standards Development and Future Technology Division, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make these regulations to enhance the safety of air navigation. An AD is considered a legislative instrument as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation mandates that the State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type, and the State of Registry must implement requirements to ensure the same.
Under these provisions, CASA is tasked with assessing information from the State of Design and issuing corresponding ADs to ensure compliance with airworthiness standards in Australia. This process involves CASA reviewing airworthiness directives issued by other ICAO Contracting States and determining if they need to be adopted or adapted for Australian conditions. For instance, CASA issued AD/PW-P/7 concerning Pratt and Whitney piston engines, but subsequently decided to cancel this directive due to the resolution of the unsafe condition it addressed. The cancellation of this AD, which will take effect on 27 August 2009, does not necessitate a replacement as the original issue no longer exists.
Obligations imposed by these regulations include CASA’s responsibility to evaluate and respond to ADs issued by the State of Design. This involves ensuring that any unsafe conditions identified in foreign ADs are appropriately addressed through the issuance of corresponding Australian ADs. Furthermore, CASA must also ensure the communication of these directives to relevant stakeholders to maintain safety standards. Additionally, the State of Registry must implement and enforce the requirements set forth in these ADs to maintain the airworthiness of individual aircraft within its jurisdiction.
Failing to comply with these ADs may result in significant consequences. Although specific offences and penalties are not detailed in the provided text, breaches of airworthiness regulations can generally lead to enforcement actions by CASA, including fines and other penalties. The severity of these penalties can vary depending on the nature and impact of the non-compliance. The overarching aim of these provisions is to ensure the highest safety standards in air navigation, and thus any breach can have serious implications for both the operators and the regulatory body.
