Overview
The Civil Aviation Regulations 1998, amended by the Civil Aviation (Airworthiness) Regulations 1998, introduced a series of legislative instruments to address safety concerns within the aviation industry. Specifically, the legislative instrument F2006B04799 pertains to the issuance of Airworthiness Directives for certain aircraft, including the Eurocopter BO 105 Series Helicopters. This directive was enacted to ensure the safety of these aircraft by addressing specific mechanical issues, such as potential interference with the swashplate drive link assembly. The policy objective behind this legislation is to mandate corrective actions to prevent accidents and ensure the continued airworthiness of the affected helicopters. The Australian Government, through the Civil Aviation Safety Authority, is the enacting body responsible for these regulations, which aim to maintain high safety standards in civil aviation.
This particular legislative instrument targets all Model BO 105 helicopters equipped with a specific swashplate and bearing ring. The directive requires operators to take action in accordance with the manufacturer's service bulletin to rectify identified issues. Compliance with this directive is mandatory, with a specified timeframe to ensure that the necessary actions are taken promptly. The directive was designed to address a problem identified in the operation of the helicopters, thereby preventing potential safety hazards that could arise from the interference with the swashplate drive link assembly.
Scope and Application
The Civil Aviation Safety Authority (CASA) established the regulations outlined in PART 39 - 105 of the Civil Aviation Regulations 1998, specifically focusing on airworthiness directives for Eurocopter BO 105 Series Helicopters. This regulation applies to all BO 105 helicopters equipped with a specific swashplate part number and bearing ring part numbers, mandating compliance with MBB Alert Service Bulletin ASB-BO 105-40-101. The directive is time-bound, requiring compliance within 25 hours of time in service after 24 June 1987 or before 31 July 1987, whichever comes first. These regulations are implemented to mitigate the risk of swashplate drive link assembly interference, which can occur during certain control inputs, ensuring safety and operational standards within the Australian aviation industry. The geographic reach of these regulations is national, applying across all states and territories of Australia, with CASA being the governing body responsible for enforcement and compliance. The regulations do not specify any exclusions, exemptions, or thresholds, and compliance is mandatory for all specified helicopters.
Key Provisions
The Civil Aviation Regulations 1998, particularly in Part 39 under the section titled "Schedule of Airworthiness Directives," addresses the maintenance and safety requirements for specific aircraft types, including the Eurocopter BO 105 Series Helicopters (section 39 - 105). This part focuses on AD/BO 105/10, which pertains to the swashplate component. This directive applies to all Model BO 105 helicopters equipped with swashplate P/N 105-41904 and bearing rings P/N 105-41936.01, 117-41937.01, or 117-41936.01. The requirement specified in this directive is to take action in accordance with the MBB Alert Service Bulletin ASB-BO 105-40-101. This action must be completed within a specific timeframe: either within 25 hours of the helicopter's time in service following 24 June 1987 or before 31 July 1987, whichever comes first.
The obligations imposed by this directive are clear and precise. Operators of Model BO 105 helicopters with the specified swashplate and bearing rings must ensure that the corrective actions outlined in the MBB Alert Service Bulletin ASB-BO 105-40-101 are implemented. These actions are aimed at mitigating the risk of interference with the swashplate drive link assembly, which can occur under certain control inputs. The directive mandates that this compliance must be achieved within the specified timeframe, ensuring the safety and airworthiness of the helicopters in question.
Failure to comply with the provisions of AD/BO 105/10 can lead to serious safety risks and potential regulatory consequences. While the Civil Aviation Regulations 1998 do not explicitly detail offences or penalties in this specific directive, non-compliance with airworthiness directives generally can result in civil or criminal penalties. These may include fines, enforcement actions, and potential grounding of the aircraft until the necessary actions are completed. The severity of the penalties can vary depending on the circumstances and the extent of the non-compliance. However, the overarching goal is to ensure that all helicopters meet the required safety standards to protect passengers, crew, and the general public.
