Overview
The Civil Aviation Regulations 1998 were enacted to ensure the safety and efficiency of civil aviation within Australia, and to provide a regulatory framework that aligns with international standards. Specifically, PART 39 - 105 of these regulations pertains to the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives, which mandate specific actions to address identified safety issues in aircraft operations. AD/BAe 146/33, issued in 1991, is an example of such directives, targeting British Aerospace BAe 146 Series Aeroplanes to rectify issues with the pitot-static system. The directive was introduced to address the problem of water traps forming in the hoses of certain BAe 146 aircraft models, which could potentially compromise the accuracy of critical flight instruments. The policy objective behind this directive is to ensure that the identified safety issues are resolved to maintain the airworthiness and operational safety of the aircraft in question.
This legislative instrument is part of a broader framework enacted by the Australian Parliament to regulate civil aviation safety, ensuring that all aircraft operating within Australian airspace meet stringent safety standards. The Civil Aviation Regulations 1998, administered by CASA, provide a comprehensive set of rules designed to mitigate risks and enhance the safety of civil aviation, thereby protecting both the public and the aviation industry.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates adherence to Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/BAe 146/33, concerns the Pito-Static System of British Aerospace BAe 146 Series aeroplanes, targeting aircraft of series 200 and 200A with Constructor’s Nos E2164 and subsequent, as well as series 300 and 300A with Constructor’s Nos E3118, E3163 and subsequent. This directive requires action in accordance with the Mandatory British Aerospace Service Bulletin 34-128-00950J and mandates compliance prior to 31 July 1991. The directive aims to address the issue of water traps forming in the hoses of post Mod. HCM 00950A&D (introduction of EFIS) aircraft, ensuring the safety and airworthiness of these specific aeroplanes within the Australian jurisdiction. This regulation extends to all operators and owners of the specified aircraft series, ensuring uniformity in compliance with safety standards across the Commonwealth of Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the requirements for the airworthiness directives, with the document AD/BAe 146/33 focusing on the pitot-static system of British Aerospace BAe 146 Series Aeroplanes. This directive mandates action in accordance with the Mandatory British Aerospace Service Bulletin 34-128-00950J (Section 105). The directive applies to all series 200 and 200A Constructor’s Nos E2164 and subsequent, and all series 300 and 300A Constructor’s Nos E3118, E3163 and subsequent (Section 105). The requirement is that the action must be completed prior to 31 July 1991 (Section 105). The background to this directive indicates that water traps have been found in the hoses fitted to post Mod. HCM 00950A&D (introduction of EFIS) aircraft, which necessitates compliance with the specified service bulletin to ensure airworthiness.
The obligations imposed by the Civil Aviation Regulations 1998 on the parties governed by this directive include ensuring that all affected British Aerospace BAe 146 Series Aeroplanes comply with the Mandatory Service Bulletin 34-128-00950J. This involves implementing the necessary actions to rectify the identified issue with the pitot-static system to prevent the formation of water traps in the hoses. Operators of these aircraft must ensure that all modifications and checks are performed by appropriately qualified personnel and that the aircraft are certified as airworthy before being returned to service.
Failure to comply with the requirements set forth in the Civil Aviation Regulations 1998, specifically this airworthiness directive, can result in significant legal consequences. The legislation does not explicitly state the penalties for non-compliance; however, it is implied that breaches could lead to enforcement actions by the Civil Aviation Safety Authority. Such actions could include the grounding of the aircraft, fines, or other administrative penalties. Additionally, failure to comply with airworthiness directives can result in civil or criminal liability, especially if non-compliance leads to an aviation incident or accident.
