Overview
The Civil Aviation Safety Regulations 1998 (CASR) were enacted to provide a comprehensive framework for ensuring the safety of civil aviation in Australia. The Regulations were established to address the need for consistent safety standards across the aviation industry, with the overarching goal of protecting the public and promoting efficient and safe air transport. Enacted by the Australian Parliament, the CASR serve as a critical component of the regulatory infrastructure overseen by the Civil Aviation Safety Authority (CASA). The policy objective of these regulations is to ensure that all civil aviation operations and aircraft meet stringent safety standards, thereby mitigating risks associated with air travel.
In the context of the 2004 legislative instrument F2006B01859, CASA issued an amendment to an existing Airworthiness Directive (AD) concerning the Airbus Industrie A320, A319, and A321 series aeroplanes. Specifically, the amendment addressed the issue of cracking in the engine rear mount barrel nuts. The directive was revised to apply only to aircraft that had not yet been modified with specific modifications or service bulletins, thereby targeting those aeroplanes that remained susceptible to the identified safety risk. This amendment was introduced to enhance safety by ensuring that all relevant aircraft were either modified or inspected according to the specified requirements.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105 and the Airworthiness Directive (AD) AD/A320/11 Amendment 1, applies to Airbus Industrie A320-231 series aeroplanes that have not incorporated modification AIRBUS INDUSTRIE 22071 or the AIRBUS INDUSTRIE Service Bulletin (SB) A320-71-1007. This AD is concerned with the engine rear mount barrel nuts, which have been identified as having the potential to crack. The requirement is for the action specified in Airbus Industrie Operator Information Telexes: ST/999.0085/90 and ST/999.0087/90, which mandate certain maintenance procedures to address the issue. Compliance with these requirements must be achieved within specific time frames, with the amendment becoming effective on 28 October 2004. The AD applies nationally within the Commonwealth of Australia and is overseen by the Civil Aviation Safety Authority (CASA), with its delegate, James Coyne, responsible for its implementation. The scope of the AD is limited to those aircraft that have not been modified or updated in accordance with the specified modifications and service bulletin, and it is notified in the Commonwealth of Australia Gazette to ensure widespread awareness and compliance.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) under the Civil Aviation Safety Regulations 1998 (CASR) are the applicability, requirement, and compliance sections (sections 2-4). Section 2 specifies that the AD applies to Airbus Industrie A320-231 series aeroplanes that have not incorporated modification AIRBUS INDUSTRIE 22071 or Service Bulletin (SB) A320-71-1007. Section 3 outlines the actions required, which involve adhering to Airbus Industrie Operator Information Telexes: ST/999.0085/90 and ST/999.0087/90. Section 4 details the timeframes for compliance, with the first requirement remaining unchanged as within 25 hours’ time in service after 12 July 1990, and the second requirement remaining unchanged as daily after the same date.
The obligations imposed by this AD on the relevant parties, primarily aircraft operators and maintenance organisations, include ensuring that the specified actions are performed on applicable aircraft within the prescribed timeframes. Specifically, operators must ensure that the aircraft undergo the actions detailed in the telexes, specifically addressing the engine rear mount barrel nuts. This involves inspecting and potentially replacing these nuts to mitigate the risk of cracking, which has been reported previously. Operators must also keep records of compliance with these requirements as per the AD's stipulations.
The AD does not explicitly state any offences, penalties, or civil/criminal consequences for non-compliance within the text provided. However, failure to adhere to ADs is generally considered a breach of CASR, which could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, legal proceedings, or the suspension of airworthiness certificates, depending on the severity and frequency of non-compliance. The potential penalties for breaches of CASR can vary widely, with maximum fines and imprisonment terms possible for serious violations.
