Overview

The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide a comprehensive regulatory framework governing the safety and efficiency of civil aviation in Australia. These regulations were introduced by the Australian Parliament to address the need for stringent and consistent safety standards within the aviation industry, ensuring the protection of passengers, crew, and the general public from aviation-related risks. The regulations establish the Civil Aviation Safety Authority (CASA) as the primary regulatory body responsible for the oversight and enforcement of aviation safety standards. A specific instance of this regulatory framework in action is seen in the Airworthiness Directive (AD) issued under subregulation 39.1 (1) of CAR 1998. This particular AD, numbered AD/DAUPHIN/57, pertains to the Eurocopter SA 360 and SA 365 (Dauphin) Series Helicopters, specifically targeting the engine air inlet sand filters. The directive mandates the inspection of sand filter ejection nozzles for cracks to prevent potential in-flight failures, reflecting a policy objective to maintain the highest standards of aviation safety through proactive measures and compliance with international safety directives.

Scope and Application

The Airworthiness Directive issued under the Civil Aviation Regulations 1998 applies specifically to Eurocopter AS 365N, N1, N2, and N3 model helicopters that incorporate CENTRISEP engine air inlet sand filters, as referenced in Eurocopter Alert Service Bulletin 71.00.14.P5. This regulatory action mandates the inspection of the sand filter ejection nozzles for cracks, in accordance with the detailed instructions provided in the aforementioned bulletin. The requirement necessitates that these inspections be conducted following each last flight of the day, effective from 16 May 2002. This directive serves to address safety concerns identified in the French DGAC Airworthiness Directive 2000-108-050 (A) R2, which was issued in response to reports of cracks in the exhaust ejection nozzles that could potentially lead to the loss of a nozzle during flight. The directive is issued by a delegate of the Civil Aviation Safety Authority and is applicable across the Commonwealth of Australia, ensuring compliance with national aviation safety standards.

Key Provisions

The main operative sections of the Airworthiness Directive (AD/DAUPHIN/57) pertain to the applicability, requirement, and compliance of the directive. According to section 5, the directive applies to Eurocopter AS 365N, N1, N2, and N3 model helicopters that incorporate CENTRISEP engine air inlet sand filters, as specified in Eurocopter Alert Service Bulletin 71.00.14.P5. Section 5 also mandates the inspection of sand filter ejection nozzles for cracks, following the instructions detailed in the same Eurocopter Alert Service Bulletin, and references DGAC AD 2000-108-050 (A) R2. Section 5 further stipulates that the compliance period for this directive is effective from 16 May 2002, and the inspection must be conducted following each last flight of the day. The obligations imposed by this AD on the parties or entities it governs are primarily focused on ensuring the safety and airworthiness of the specified Eurocopter helicopter models. Operators and owners of the affected aircraft are required to inspect the sand filter ejection nozzles for any cracks as per the instructions outlined in Eurocopter Alert Service Bulletin 71.00.14.P5. This inspection must be carried out following each last flight of the day, and the directive becomes effective from 16 May 2002. Failure to comply with this AD may result in non-compliance with safety standards, potentially leading to operational restrictions or penalties. In terms of consequences for non-compliance, while the AD itself does not explicitly state specific offences, penalties, or civil/criminal consequences, it is important to note that the Civil Aviation Regulations 1998 under which this AD is issued may impose penalties for non-compliance with ADs. The maximum penalties for non-compliance with airworthiness directives can include fines, imprisonment, or both, depending on the severity of the breach. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations and take appropriate action against operators or entities that fail to comply with the requirements of the AD.
