Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were introduced to address the need for comprehensive safety regulations in the civil aviation sector. This legislative instrument provides the regulatory framework for ensuring that all civil aviation activities within Australia adhere to stringent safety standards. One particular aspect of this regulation is captured in the Airworthiness Directives, which are designed to address specific safety concerns related to aircraft models. For instance, AD/AC-SNOW/11 pertains to the inspection of the Carburettor Air Selector Valve Assembly in Ayres Thrush (Snow) Commander Series Aeroplanes, specifically Model S-2R with serial numbers 5000 and above. This directive mandates inspections within 50 hours of time in service following 30 April 1978 and at subsequent intervals not exceeding 50 hours of service, ensuring that these aircraft meet necessary safety standards and are airworthy. The overarching policy objective is to maintain the highest levels of safety and reliability in civil aviation operations. The enacting body for these regulations is the Parliament of Australia, which aims to protect the public by ensuring that all aircraft operating within Australian airspace are subject to rigorous safety checks and compliance measures. The specific directive for the Ayres Thrush (Snow) Commander Series Aeroplanes is intended to mitigate any potential risks associated with the Carburettor Air Selector Valve Assembly, ensuring the continued safety and reliability of these aircraft in operation. By setting clear and enforceable standards, the Civil Aviation Regulations 1998 contribute to the broader goal of maintaining a safe and efficient civil aviation system in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Ayres Thrush (Snow) Commander Series Aeroplanes, more precisely the Model S-2R with serial numbers 5000 and above. This regulation mandates the inspection of the carburettor air selector valve assembly as outlined in Rockwell International Service Bulletin No. SB-AG-8.3/78. The inspection must be conducted within 50 hours of the aircraft's time in service following 30 April 1978, and subsequently at intervals not exceeding 50 hours of time in service. This regulation applies to the Commonwealth of Australia and falls under the jurisdiction of the Civil Aviation Safety Authority. The scope of the regulation is narrowly focused on the specified model of aeroplanes and their maintenance, and it does not explicitly state any exclusions or exemptions, implying that compliance is mandatory for all affected aircraft. The regulation can be extended or restricted through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, are focused on ensuring the ongoing airworthiness of specific aircraft models through scheduled inspections and compliance measures. For instance, the Ayres Thrush (Snow) Commander Series Aeroplanes, specifically model S-2R with serial numbers 5000 and above, are mandated to undergo inspections of the Carburettor Air Selector Valve Assembly (Section AD/AC-SNOW/11). This inspection must be performed within 50 hours of time in service following 30 April 1978 and subsequently at intervals not exceeding 50 hours of time in service (Section AD/AC-SNOW/11). Compliance with these directives is critical to maintaining the safety standards set by the Civil Aviation Safety Authority (CASA). The Act imposes several obligations on the parties or entities it governs, particularly the owners and operators of the affected aircraft. These obligations include ensuring that the required inspections are conducted in accordance with the specified timelines and intervals. For example, the owner or operator of an Ayres Thrush (Snow) Commander Series Aeroplane model S-2R with serial numbers 5000 and above must schedule and complete the inspection of the Carburettor Air Selector Valve Assembly within 50 hours of time in service after 30 April 1978 and then at intervals not exceeding 50 hours of time in service. This is detailed in Section AD/AC-SNOW/11 of the document Rockwell International SB No. SB-AG-8.3/78. Failure to adhere to these inspection requirements can lead to significant safety risks and potential regulatory action. Failure to comply with the provisions outlined in the Civil Aviation Regulations 1998 can result in severe consequences, including both civil and criminal penalties. Under the Act, non-compliance with the Airworthiness Directives can lead to enforcement actions by CASA, which may include fines, suspension or revocation of airworthiness certificates, and other regulatory sanctions. The maximum penalties for such breaches are substantial, reflecting the critical importance of maintaining airworthiness standards. Operators found in breach of the inspection requirements specified in Section AD/AC-SNOW/11 may face fines of up to $275,000 for a corporation and $55,000 for an individual, as well as potential criminal charges for serious safety violations. These penalties underscore the serious nature of non-compliance and the importance of adhering to the regulatory requirements to ensure the safety of all air operations.
