AD/CESSNA 310/3 - Oxygen Line - Modification

Overview

The Civil Aviation Regulations 1998, as amended and administered by the Civil Aviation Safety Authority (CASA), is a comprehensive set of rules governing civil aviation in Australia. Among its numerous provisions, Part 39 focuses on airworthiness directives, ensuring that aircraft meet safety standards. One such directive, AD/CESSNA 310/3, pertains to the Cessna 310 series aeroplanes and specifically addresses the modification of the oxygen line. This legislation was introduced to ensure the safety of pilots and passengers by mandating timely compliance with specified modifications for the oxygen systems on Cessna 310 series aeroplanes. The policy objective, as stated within the text, is to ensure that these aircraft are operated safely and within the standards set by CASA. The directive applies to all models of Cessna 310 aeroplanes that are equipped with oxygen systems and requires compliance forthwith to mitigate any potential safety risks associated with the oxygen line.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives concerning the Cessna 310 Series Aeroplanes. This regulation applies to all models of Cessna 310 aircraft that are equipped with oxygen systems, as identified by Cessna Service Letter No. 310-7. The directive mandates that any deficiencies or safety concerns related to the oxygen lines must be rectified immediately upon the issuance of the directive. The scope of this regulation is comprehensive in its application to all relevant aircraft models within the specified category, ensuring adherence to safety standards across the aviation industry. The geographic reach of these regulations is national, applying throughout the Commonwealth of Australia, thereby ensuring a uniform standard of safety is maintained across all jurisdictions. No specific exclusions, exemptions, or thresholds are mentioned within the provided text, indicating that the directive applies broadly to the targeted aircraft models without exception. The regulations may be extended or further specified through subordinate instruments, which would provide additional detail and clarification on implementation and compliance.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, mandate specific requirements for the airworthiness of Cessna 310 series aeroplanes, particularly focusing on the oxygen line modification as outlined in AD/CESSNA 310/3. This airworthiness directive applies to all models of Cessna 310 series aeroplanes equipped with oxygen systems. The directive is identified as Cessna SL No. 310-7 and requires compliance forthwith. The key provision of this directive (Section 39.105) mandates that all Cessna 310 series aeroplanes equipped with oxygen systems must undergo a specific modification to the oxygen line. This modification is essential to ensure the safety and reliability of the oxygen supply system. The requirement is clear: the modification must be completed immediately, with no permissible delay, as stipulated by the phrase "forthwith" in the document. Entities governed by this legislation must adhere to the directive by implementing the required modifications to the oxygen lines of their Cessna 310 series aeroplanes. This obligation ensures that the aircraft meet the stringent safety standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with these airworthiness directives can have serious consequences for both the operators and the safety of the passengers and crew. In terms of consequences, any non-compliance with the airworthiness directive can result in significant civil and potentially criminal penalties. While the specific penalties are not detailed in the provided excerpt, non-compliance with CASA directives can generally lead to fines, enforcement actions, and potential grounding of the aircraft. Additionally, if such non-compliance results in an accident or incident, it could lead to more severe criminal charges against the responsible parties. Ensuring compliance is therefore crucial to avoid these adverse outcomes.
