Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, include an Airworthiness Directive (AD) aimed at ensuring the safety of British Aerospace BAe 146 Series aeroplanes. The AD, titled "Pylon to Engine Front Mount Yoke Bush" (AD/BAe 146/18), was enacted to address the issue of the pylon to engine front mount yoke bush being found incorrectly installed, which poses a safety risk. This directive applies to specific series and serial numbers of BAe 146 aeroplanes, mandating corrective actions as outlined in BAe Service Bulletin 54-4. Compliance with this directive is required in accordance with the specified Requirement Document. The enactment of this regulation by the Civil Aviation Safety Authority under the Civil Aviation Act 1988 underscores the commitment to maintaining stringent safety standards within the aviation industry, thereby mitigating potential risks associated with incorrect installations.
The policy objective behind this AD is to ensure the continued airworthiness and safety of the BAe 146 Series aeroplanes by enforcing compliance with precise installation procedures as detailed in the service bulletin. By mandating adherence to these specific guidelines, the Civil Aviation Safety Authority aims to prevent occurrences of incorrect installations that could compromise the structural integrity and operational safety of the aircraft. This directive serves as a crucial regulatory measure to uphold the high safety standards required in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, under the jurisdiction of the Commonwealth of Australia, specifically Part 39 - 105, addresses the issuance of airworthiness directives through the Civil Aviation Safety Authority. This regulation applies to certain British Aerospace BAe 146 Series Aeroplanes, namely those of Series 200 with serial numbers E2106, E2111, E2115, E2121, and E2127, and Series 300 with serial numbers E3128, E3131, and E3134. The directive mandates compliance with British Aerospace Service Bulletin SB 54-4 concerning the pylon to engine front mount yoke bush, responding to a reported instance of incorrect installation of the subject bush. Compliance with this directive must be achieved in accordance with the specified requirement document, ensuring the continued airworthiness of the affected aircraft. The regulation does not explicitly extend its application through subordinate instruments but relies on the referenced service bulletin for compliance details.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, establish the safety standards for certain aircraft. For British Aerospace BAe 146 Series Aeroplanes, AD/BAe 146/18 addresses a critical issue concerning the pylon to engine front mount yoke bush. The directive applies to Series 200 with serial numbers E2106, E2111, E2115, E2121, and E2127, as well as Series 300 with serial numbers E3128, E3131, and E3134. The requirement is for all affected aircraft to be serviced in accordance with BAe Service Bulletin 54-4, ensuring that the pylon to engine front mount yoke bush is correctly installed as specified in the requirement document.
Compliance with AD/BAe 146/18 involves meticulous adherence to the outlined procedures and specifications provided in the BAe Service Bulletin 54-4. Operators of the specified BAe 146 Series Aeroplanes must ensure that the maintenance and inspection processes are performed correctly to rectify any incorrectly installed yoke bush. This directive underscores the importance of maintaining the structural integrity and operational safety of the aircraft by ensuring that all components are installed as per the manufacturer’s guidelines.
Operators of the BAe 146 Series Aeroplanes are legally obligated to comply with the directives laid out in AD/BAe 146/18. This includes conducting the necessary inspections, maintenance actions, and ensuring that all work is carried out in strict accordance with the BAe Service Bulletin 54-4. Failure to comply with these obligations may result in the aircraft not meeting the required airworthiness standards, which could potentially compromise flight safety.
Failure to adhere to the requirements of AD/BAe 146/18 can lead to significant legal and operational consequences. The Civil Aviation Safety Authority has the authority to enforce compliance, and non-compliance may result in the grounding of the affected aircraft until the required actions are completed. Under the Civil Aviation Act 1988, penalties for non-compliance can include substantial fines and, in severe cases, criminal charges against individuals or corporations responsible for the oversight. The specific penalties can vary, but they are designed to enforce strict adherence to safety regulations to protect public safety in aviation.
