Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a crucial component of the regulatory framework governing civil aviation safety in Australia. Among these regulations, Part 39 – 105 specifically pertains to the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, which are designed to ensure that aircraft meet the required safety standards. One such directive, AD/BEECH 65/35 Amendment 1, addresses a particular safety concern with the Beechcraft 65 and 70 (Queen Air) series aeroplanes, mandating inspections and necessary modifications to the port inner wing electrical wiring to prevent potential chafing and associated safety risks. This directive was introduced to address the identified gap in ensuring the structural integrity and safety of these specific aircraft models, thereby contributing to the overarching policy objective of maintaining high safety standards within the civil aviation sector.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the scope and application of airworthiness directives pertinent to civil aviation in Australia. This particular legislative instrument, AD/BEECH 65/35 Amendment 1, applies to all models of the Queen Air 65 and 70 series aeroplanes. This means that the directive is mandatory for aircraft manufacturers, operators, and maintenance personnel involved with these specific models. The directive requires a detailed inspection of the electrical wiring in the port inner wing, focusing on potential chafing where the loom passes a specific stiffener, as well as measures to support the loom to prevent further damage. Compliance with these requirements is necessary within 100 hours of time in service after 28 February 1973, ensuring that the aircraft maintain a safe operational standard. This regulation extends across the Commonwealth of Australia and is overseen by the Civil Aviation Safety Authority. Subordinate instruments may further detail the implementation and enforcement of these directives.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, includes the AD/BEECH 65/35 Amendment 1 for Beechcraft 65 and 70 (Queen Air) Series Aeroplanes (AD/BEECH 65/35). This amendment pertains to the port inner wing electrical wiring, and it was issued on 3 August 1989. The directive applies to all models within the Queen Air 65 and 70 series (AD/BEECH 65/35). The primary requirement under this directive is to inspect the electrical loom in the port inner wing for any chafing where the loom passes the stiffener, specifically LH P/No. 50-120006-6, as illustrated in the Beechcraft A65, 70 and B80 parts catalogue (Figure 66). Additionally, the directive mandates that the loom be adequately supported to prevent further chafing. This inspection and support must be completed within 100 hours of the aircraft's time in service after 28 February 1973 (AD/BEECH 65/35).
The obligations imposed by this directive are clear and specific. Operators of Beechcraft 65 and 70 series aircraft must ensure that the required inspections and support measures are implemented within the specified timeframe. This means that maintenance personnel must conduct a thorough examination of the electrical wiring in the designated area, identify any signs of wear or damage, and take appropriate steps to support the wiring to prevent future chafing. This involves not only the inspection but also the execution of corrective actions if any issues are found, ensuring the wiring is secure and protected.
Failure to comply with the requirements set out in the AD/BEECH 65/35 Amendment 1 can lead to significant consequences. While the specific penalties for non-compliance are not detailed in the text, non-adherence to airworthiness directives generally can result in severe penalties under civil aviation laws. These may include fines, operational restrictions, or even the grounding of the aircraft until compliance is achieved. Such non-compliance not only risks safety but can also lead to legal and financial repercussions for the operators involved.
