Overview
The Civil Aviation Regulations 1998, as amended through the legislative instrument F2006B03609, address safety concerns associated with the service life of exhaust bellows on Beagle B206 Series aeroplanes. This regulation was introduced to mitigate the risk of structural failure in exhaust bellows, which could potentially lead to catastrophic engine failure and compromise the safety of the aircraft and its occupants. The regulation was enacted by the Australian Government under the authority of the Civil Aviation Act 1988, with the policy objective being to ensure the ongoing airworthiness and safety of the specified aircraft models by enforcing a rigorous schedule for the inspection and replacement of critical components. The requirement to retire specific exhaust bellows parts aims to preemptively address wear and tear issues, thereby maintaining the integrity of the aircraft's operational safety standards.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the airworthiness directives for certain types of aircraft, including the Beagle B206 Series Aeroplanes. This legislation applies to the specified model of aeroplanes and mandates the retirement of exhaust bellows with certain part numbers, namely P/N CE20901 and P/N CE20806, due to their potential impact on aircraft safety. The regulations are enforced by the Civil Aviation Safety Authority (CASA) and have a national reach within Australia, ensuring that the outlined safety directives are adhered to across the Commonwealth. The applicability of these directives is not limited to specific entities but rather applies to all operators of the Beagle B206 Series Aeroplanes. The regulations provide specific timelines for compliance based on the total time in service of the exhaust bellows, thus ensuring that the aircraft maintain a high standard of airworthiness. The Civil Aviation Regulations do not specify exclusions or exemptions for these directives, indicating that all affected aircraft must comply with the outlined requirements.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105 (F2006B03609), includes an Airworthiness Directive (AD) concerning the exhaust bellows of the Beagle B206 Series aeroplanes, denoted as AD/BEA 206/6. This regulation mandates the retirement of specific exhaust bellows parts (paragraph 9/69). The affected parts are identified by the part numbers CE20901 and CE20806. The directive applies to the Model B206 Series 2 aeroplanes.
Under the AD, there are clear requirements regarding when the specified exhaust bellows must be retired from service. For exhaust bellows that have accumulated more than 500 hours of total time in service as of 29 September 1969, they must be retired within the next 100 hours of service following that date. Conversely, for those bellows that have less than 500 hours of service at that time, they should be retired before reaching 600 hours of total service time and subsequently at intervals not exceeding 600 hours (paragraph 1). Additionally, it is noted that further information can be found in the Beagle B206, Series 2, Maintenance Schedule, Volume 5, page 40-8, dated 30 April 1967.
Operators and maintenance personnel of the Beagle B206 Series aeroplanes are obligated to ensure compliance with these directives. They must meticulously monitor the operational hours of the exhaust bellows parts in question and retire them as stipulated by the AD. Failure to adhere to these requirements may result in the aeroplane not being deemed airworthy, which could have serious implications for safety and legality in air operations.
Failure to comply with the provisions of this AD can lead to various consequences. While the Civil Aviation Regulations 1998 do not explicitly detail specific penalties for non-compliance in this context, non-compliance with airworthiness directives generally can result in significant repercussions. These may include fines, penalties, and potential criminal charges if the non-compliance is deemed to have contributed to an aviation accident or incident. Additionally, operators may face enforcement actions from the Civil Aviation Safety Authority, which could include the grounding of affected aircraft until the non-compliance is rectified.
