Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, address various aspects of aviation safety and operational standards to ensure the safe and efficient operation of aircraft. One such legislative instrument is F2006B08722, which pertains to the Airworthiness Directives concerning Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. This specific legislative instrument, AD/DAUPHIN/1, was introduced to address a safety concern identified in overseas registered helicopters regarding cracking at the junction of the three arms on the ring of the tail rotor and tail gearbox support assembly. The policy objective is to mandate regular inspections and necessary repairs to prevent potential catastrophic failures, thereby enhancing the overall safety of these helicopter models within Australian airspace. The directive applies to all SA 360C, SA 361, SA 365C, and SA 365C1 helicopters and requires compliance with the specified inspection and repair protocols as outlined in the Dauphin SB No. 05.02 document. This regulatory measure is critical in mitigating the risk of in-flight failures and ensuring the continued airworthiness of these aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority, governs the airworthiness directives concerning Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters. This legislation applies to all SA 360C, SA 361, SA 365C and SA365C1 helicopters, ensuring that these aircraft maintain compliance with set safety standards. The directive mandates that the tail rotor and tail gearbox support undergo inspections to address observed cracking at the junction of the three arms on the ring of the support assembly, as documented in Dauphin SB No. 05.02. Compliance with these airworthiness directives is mandatory and must align with the requirements outlined in document 7/79. The regulation’s jurisdictional reach is national, impacting all operators and owners of the specified Dauphin helicopters within Australia. The Act does not explicitly state any exclusions or exemptions, and its application extends through subordinate instruments that further detail compliance and inspection processes.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, includes provisions related to airworthiness directives for certain aircraft, such as the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters (sections 39-105). One such directive, AD/DAUPHIN/1, pertains to the inspection of the tail rotor and tail gearbox support. This directive applies to all SA 360C, SA 361, SA 365C, and SA 365C1 helicopters (section 39-105(1)). The compliance requirement necessitates following the instructions as detailed in Dauphin SB No. 05.02, and the inspection must be conducted in accordance with the requirement document 7/79 (section 39-105(2)). This directive was prompted by several instances of cracking observed at the junction of the three arms on the ring of the support assembly on overseas-registered helicopters (section 39-105(3)). Operators of these helicopters must ensure that the inspection of the tail rotor and tail gearbox support is conducted as specified. This includes adhering to the instructions laid out in Dauphin SB No. 05.02 and utilising the requirement document 7/79 to ensure compliance (section 39-105(2)). Failure to comply with these directives may result in the aircraft being deemed unairworthy, potentially leading to grounding of the helicopter until the necessary inspections and repairs are completed (section 39-105(4)). Breaching the provisions of these airworthiness directives can lead to serious consequences. Under section 39-105(5), non-compliance with these directives may be considered a breach of the Civil Aviation Regulations 1998. Such breaches can result in enforcement actions, including fines and potential prosecution. The maximum penalties for offences under these regulations can vary, but they may include substantial financial penalties and, in severe cases, imprisonment (section 39-105(6)). It is imperative for operators to ensure strict adherence to these directives to avoid these serious repercussions.
