AD/BEECH 65/27 Amdt 1 - Fuel Vent Heater Wiring

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, aim to ensure the safety and efficiency of civil aviation within Australia. The specific legislative instrument F2006B04124 pertains to Part 39 - 105, which outlines the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for certain aircraft types, including Beechcraft 65 and 70 (Queen Air) series aeroplanes. This instrument was introduced to address potential safety hazards associated with the electrical systems of these aircraft models, particularly concerning the fuel vent heater wiring. The policy objective is to mitigate risks by mandating specific maintenance actions, such as disconnecting electrical power supplies and inspecting for wiring chafing, thereby ensuring the continued airworthiness of the aircraft in operation.

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 Beechcraft 65 and 70 (Queen Air) Series Aeroplanes. This legislation applies to all model Queen Air 65 and 70 aeroplanes equipped with electrical fuel vent heaters. The regulation requires operators to disconnect the electrical power supply to both fuel vent heaters and install a warning placard or tag indicating the system is inoperative, ensuring that if a circuit breaker is tripped, a clip is placed over the shank to prevent inadvertent resetting. Additionally, operators must inspect the fuel vent heater electric wiring in the wing area for signs of chafing and either secure the wiring to prevent further chafing or cover the wiring with plastic sleeving. Compliance is required within a specified timeframe, with certain actions needing to be completed within 10 hours’ time in service after 30 September 1971, and other inspections and fixes mandated before reconnecting the fuel vent heaters to the electrical power supply. This regulation extends across the Commonwealth of Australia, ensuring consistent standards and safety measures in civil aviation.

Key Provisions

The main operative sections of this legislation, specifically AD/BEECH 65/27 Amendment 1, address the safety concerns associated with the fuel vent heater wiring of Beechcraft 65 and 70 series aeroplanes. According to section 1 of the amendment, the requirement is to disconnect the electrical power supply to both fuel vent heaters and install a warning placard or tag indicating that the system is inoperative (section 1.1). If the disconnection is achieved by tripping the appropriate circuit breaker, a clip must be placed over the shank of the circuit breaker to prevent inadvertent resetting (section 1.1). Section 2 mandates that operators inspect the fuel vent heater electric wiring in the wing area for signs of chafing (section 2). Section 3 requires that either the wiring be secured to prevent chafing or the wiring be covered with plastic sleeving to prevent chafing (section 3). Compliance timelines are specified, with section 1.1 requiring action within 10 hours of service after 30 September 1971, while sections 2 and 3 must be addressed before reconnecting the fuel vent heaters to the electrical power supply. The obligations and requirements imposed by the Act on the parties or entities it governs include the disconnection of electrical power to the fuel vent heaters, the installation of warning placards or tags, and the inspection and possible securing or covering of the electric wiring to prevent chafing. Operators must ensure that the electrical power to the fuel vent heaters is disconnected and that a warning placard or tag is installed, with the additional requirement to prevent the circuit breaker from being inadvertently reset. Furthermore, operators must inspect the fuel vent heater electric wiring for signs of chafing and either secure the wiring or cover it with plastic sleeving to prevent future chafing. These obligations must be fulfilled within the specified timeframes to maintain compliance with the regulations. Failure to adhere to the provisions outlined in the Act may result in civil or criminal consequences, although the specific penalties are not detailed within the text. The regulatory framework surrounding the Civil Aviation Regulations 1998 suggests that breaches could lead to enforcement actions by the Civil Aviation Safety Authority (CASA), potentially resulting in fines, enforcement notices, or other regulatory sanctions. The severity of the penalties would depend on the nature and extent of the breach, as well as any resultant safety implications. While the exact penalties are not specified in the provided text, it is clear that compliance is critical to avoid adverse outcomes.
