AD/DAUPHIN/37 - Tripod

Overview

The Civil Aviation Regulations 1998, as part of the broader framework to ensure aviation safety, were enacted to maintain high standards of safety within Australia’s civil aviation sector. The 1998 Regulations, administered by the Civil Aviation Safety Authority (CASA), were developed to address the need for stringent safety measures and compliance with international standards. The specific legislative instrument F2006B08748 within these Regulations, focuses on Airworthiness Directives for specific aircraft types, such as the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. This directive aims to ensure that certain maintenance actions are undertaken to address identified safety issues, such as cracks at the tripod ring of the helicopters, thereby mitigating potential risks associated with corrosion and ensuring the continued airworthiness of these aircraft. This Airworthiness Directive, AD/DAUPHIN/37, targets Model SA 365 N helicopters equipped with a particular tripod part, and mandates compliance with Eurocopter’s Service Bulletin 01.28b to address a specific safety concern related to tripod ring cracks. By implementing this directive, the objective is to enforce corrective actions to enhance the structural integrity of the affected helicopters, thereby preventing potential in-flight failures and ensuring the safety of all persons onboard. This directive is a clear demonstration of the ongoing commitment to maintaining rigorous safety standards within Australia's civil aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives for various aircraft, including the Eurocopter SA 360 and SA 365 (Dauphin) series helicopters. This regulation applies to model SA 365 N helicopters equipped with a specific tripod part number, 360A23-0024-09. The directive necessitates compliance with Eurocopter Telex Service Bulletin 01.28b, which addresses a safety concern regarding a crack discovered at the root of one of the tripod's three arms. The crack was found to have originated from a corrosion site, prompting a requirement for action as specified in the Requirement Document. The directive is enforced under the authority of the Civil Aviation Safety Authority and is intended to ensure the continued airworthiness of the affected helicopters by mitigating potential safety hazards. The scope of this regulation is national, applying throughout Australia, and it extends to all entities operating such helicopters within the jurisdiction. There are no specific exclusions or thresholds mentioned in the directive, and compliance must be achieved unless the required action has already been completed as per the directive’s specifications.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39, addresses airworthiness directives that are crucial for maintaining the safety standards of aircraft in Australia. Section 39-105 of the Regulations pertains to the Airworthiness Directives (AD) for Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. This section mandates that for model SA 365 N helicopters equipped with a tripod part number 360A23-0024-09, certain actions must be taken to ensure the safety of the aircraft (Section 39-105). The directive requires that the action be carried out in accordance with the instructions outlined in Eurocopter Telex Service Bulletin 01.28b, referencing DGAC AD 88-188-024(B)R1 for further guidance. Operators and owners of the specified SA 365 N helicopters are obligated to comply with this airworthiness directive. This means that they must ensure that any identified issues with the tripod ring, such as a crack at the root of one of the three arms, are addressed. The requirement is that these actions must be completed unless they have already been accomplished as specified in the Requirement Document. This directive ensures that the identified safety issue, which stems from a crack that originated at a corrosion site, is rectified to prevent potential in-flight failures or hazards. Failure to adhere to the requirements stipulated in the airworthiness directive can lead to severe consequences. The Civil Aviation Regulations 1998 establish that non-compliance with these safety directives can result in both civil and criminal penalties. For instance, individuals or corporations that fail to comply with the AD may face fines and other legal repercussions. The specific penalties are outlined in the broader regulatory framework of the Civil Aviation Act 1988, which can impose substantial financial penalties and even imprisonment for serious breaches of aviation safety regulations. This underscores the importance of adhering to the AD to avoid any legal and safety repercussions.
