AD/DAUPHIN/25 - MGB Support Bar Shackle

Overview

The Civil Aviation Regulations 1998, specifically in PART 39 - 105, establishes the Civil Aviation Safety Authority Schedule of Airworthiness Directives for the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters, targeting the issue of the MGB Support Bar Shackle. Enacted by the Australian Government, this legislative instrument was introduced to address the critical safety issue identified with the cracking of one of the main gearbox support bar shackles on the specified helicopter models. The Civil Aviation Safety Authority (CASA) mandated compliance with Aerospatiale Service Telex 01-27, requiring corrective action within 10 hours of the helicopters being in service after 13 July 1990. The policy objective behind this directive is to enhance aviation safety by ensuring that the identified structural defect is rectified promptly, thereby mitigating potential risks associated with the operation of these helicopters. The regulations are a direct response to the need for stringent safety measures in civil aviation, reflecting the commitment of the Australian Government and CASA to maintaining high safety standards in the aviation industry. By addressing specific mechanical issues through such directives, the legislation aims to prevent accidents and ensure the continued airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, as part of the legislative instrument F2006B08736, apply to all model SA 360C, SA 361 and SA 365C, C1, C2 and C3 helicopters operating within the Commonwealth of Australia. The regulations are enforced by the Civil Aviation Safety Authority (CASA) and pertain to the maintenance and operational standards of these helicopters. This legislation mandates compliance with specific directives aimed at ensuring the airworthiness of the affected aircraft models. The requirement outlined in Airworthiness Directive AD/DAUPHIN/25 mandates action in accordance with Aerospatiale Service Telex 01-27, specifically addressing the issue of a cracked gearbox support bar shackle. Compliance with these directives must be achieved within 10 hours of the helicopter being in service after 13 July 1990. This directive does not extend beyond the specified helicopter models and is directly related to addressing the identified safety concern without broader application to other aircraft or industries.

Key Provisions

The Civil Aviation Regulations 1998, Part 39, specifically Section 105, details the Airworthiness Directives for the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. AD/DAUPHIN/25 pertains to the MGB Support Bar Shackle and is applicable to all model SA 360C, SA 361, and SA 365C, C1, C2, and C3 helicopters. This directive requires action in accordance with Aerospatiale Service Telex 01-27. Compliance with this directive must be achieved within 10 hours of time in service after 13 July 1990. The directive was issued due to the discovery of cracks in one of the main gearbox support bar shackles, necessitating immediate attention to ensure airworthiness and safety. The obligations imposed by this directive are clear and specific. Operators of the affected helicopters must follow the instructions provided in Aerospatiale Service Telex 01-27 to address the identified issue with the MGB Support Bar Shackle. This includes inspecting the shackle, repairing any cracks, and ensuring that the repair meets the specified safety standards. Compliance must be achieved within a strict timeframe, specifically within 10 hours of time in service after 13 July 1990. Failure to comply with these requirements can result in the helicopter being deemed unairworthy, potentially leading to severe safety risks. Failure to comply with the directives outlined in AD/DAUPHIN/25 can result in significant consequences. Non-compliance with airworthiness directives is a serious matter under the Civil Aviation Regulations 1998. The Civil Aviation Safety Authority (CASA) has the authority to enforce penalties and take regulatory action against operators who do not adhere to these directives. In the event of non-compliance, CASA may issue a Notice of Proposed Civil Penalty, which can lead to substantial fines. Additionally, continued operation of a non-compliant aircraft poses a risk to safety, which can result in enforcement actions, including grounding the aircraft until compliance is achieved. In terms of penalties, the Civil Aviation Regulations 1998 provide for a range of civil and criminal consequences for non-compliance with airworthiness directives. Civil penalties can include fines up to a specified maximum amount, as determined by CASA. For instance, the maximum civil penalty for non-compliance with airworthiness directives can be significant, reflecting the seriousness of the safety risks involved. Moreover, criminal penalties may apply in cases of gross negligence or willful disregard for safety regulations, leading to potential imprisonment. These stringent measures underscore the importance of adhering to the directives to maintain the highest standards of aviation safety.
