AD/SF340/10 - Fuel System Optical Sensor Bonding

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive framework governing all aspects of civil aviation within Australia. Among the many parts and schedules, Part 39 addresses specific safety measures and directives essential for maintaining the airworthiness of aircraft. One such directive, AD/SF340/10, pertains to the Saab SF340 series aeroplanes and specifically targets the bonding of fuel system optical sensors. This directive was introduced to address a safety issue identified by the manufacturer, SAAB, wherein the fitting of a jumper assembly on the mid-level and tank full optical sensors was omitted in some aircraft, potentially leading to hazardous situations if a lightning strike were to occur. The directive aims to ensure compliance with the requirements outlined in SAAB Service Bulletin SF340-28-006 and references Swedish Airworthiness Directive SAD No 1-025, mandating that the necessary corrective actions be completed before 6 October 1988. This legislative instrument underscores the importance of stringent safety measures in civil aviation, ensuring that aircraft maintain operational safety standards as required by the Civil Aviation Safety Authority. The directive reflects a collaborative effort between the Australian and Swedish authorities to address safety concerns and enhance the reliability of the Saab SF340 series aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's schedule of airworthiness directives, applies to all SAAB SF 340 series aeroplanes with serial numbers ranging from -004 to -106. This regulation mandates compliance with SAAB Service Bulletin SF340-28-006, which addresses the bonding of fuel system optical sensors, as referenced in Swedish Airworthiness Directive SAD No 1-025. The requirement stipulates that the corrective action must be completed before 6 October 1988. Failure to adhere to this directive could result in hazardous situations, particularly if a lightning strike occurs due to the omission of the jumper assembly fitting on the mid-level and tank full optical sensors. The regulation extends its reach to ensure the safety and compliance of the specified aircraft within the Commonwealth of Australia, thereby maintaining stringent safety standards in civil aviation.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the requirements for ensuring the airworthiness of aircraft. The Schedule of Airworthiness Directives under this part details specific directives issued for various aircraft models. One such directive, AD/SF340/10, pertains to the SAAB SF340 series aeroplanes, focusing on the fuel system optical sensor bonding. This directive applies to aircraft with serial numbers ranging from -004 through -106 (Section 1). It mandates that actions be taken in accordance with SAAB Service Bulletin SF340-28-006, and references Swedish Airworthiness Directive SAD No 1-025 for further context (Section 2). The directive stipulates that compliance must be achieved before 6 October 1988 (Section 3). Under the Civil Aviation Regulations, the parties governed by this directive, primarily the aircraft operators and maintenance providers, have specific obligations. They must ensure that the mid-level and tank full optical sensors on the SAAB SF340 series aircraft are fitted with the appropriate jumper assembly. This requirement is crucial to prevent hazardous situations that could arise from a lightning strike. The directive underscores the importance of adhering to the SAAB Service Bulletin and Swedish Airworthiness Directive to maintain the safety standards required by the Civil Aviation Regulations. Failure to comply with the provisions outlined in the AD/SF340/10 directive could result in significant consequences. The Civil Aviation Regulations impose penalties for non-compliance with airworthiness directives, which may include fines, suspension, or revocation of airworthiness certificates. Additionally, any resultant accidents or incidents caused by non-compliance could lead to criminal charges against the responsible parties. The maximum penalties are not explicitly stated in the directive but are generally aligned with the broader framework of the Civil Aviation Act 1988, which includes potential fines and imprisonment for serious breaches. The regulatory framework under the Civil Aviation Regulations 1998 is designed to ensure that all stakeholders are aware of their obligations and the consequences of failing to meet these standards. By adhering to the AD/SF340/10 directive, operators and maintainers of SAAB SF340 series aircraft can ensure compliance with the stringent safety requirements set forth by the Civil Aviation Safety Authority. This not only protects the aircraft and its occupants but also contributes to the overall safety of the aviation industry.
