Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to ensure the safety of civil aviation operations in Australia. They provide the framework for the regulation of civil aviation, including airworthiness standards and directives. One such directive, AD/SF340/79 Amendment 1, addresses an issue with the Saab SF340 series aeroplanes where smoke or burning smells were reported in the cabin due to incorrect brush insulation in the electric fan motor. This Airworthiness Directive (AD) was issued by the Civil Aviation Safety Authority (CASA) to rectify this safety issue by mandating the replacement of certain air recirculation fans with improved models. The policy objective of this directive is to enhance the safety of civil aviation by mitigating the risk of smoke or burning smells in the cabin, thereby protecting passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998 under the Australian Civil Aviation Safety Authority (CASA) govern the airworthiness of aircraft, including specific Airworthiness Directives (ADs) for particular models. Part 39 - 105 of these regulations details ADs for the SAAB SF340 Series aeroplanes. The ADs apply to specified serial numbers of the SAAB SF340A model, namely those from -004 through -108, unless a certain service bulletin (SB 340-21-018, Modification 1421) has been incorporated. The directive requires the replacement of certain air recirculation fans to address issues of smoke or burning smell caused by incorrect brush insulation in the electric fan motor. The requirement mandates replacing fans with a particular part number in accordance with specified service bulletins and within defined timeframes from the original issue or amendment of the directive. The ADs have a national jurisdictional reach within Australia and are enforced by CASA, with compliance monitored and enforced by authorised personnel. The ADs can be amended to include additional requirements or modifications, as seen with the amendment to AD/SF340/79, which identifies additional fans to be replaced and was effective from 9 August 2001.
Key Provisions
The key operative sections of this Airworthiness Directive (AD) primarily involve the replacement of specific parts within the Saab SF340 Series Aeroplanes to address safety concerns. Section (a) specifies the applicability of the directive, which in this case applies to Saab SF340A aircraft with serial numbers ranging from -004 through -108 that have not incorporated the SAAB Aircraft AB Service Bulletin (SB) 340-21-018 (Modification 1421). Section (b) outlines the requirements for the replacement of certain air recirculation fans, with instructions for the replacement of fans P/N C209-690C with fans P/N C209-690D as per the specified service bulletins. Section (c) indicates the compliance timelines, with the original requirement mandating action within 1000 hours of time in service after the directive's issue date, and the amendment requiring action within 500 hours of time in service after the amendment's effective date.
The AD imposes several obligations on the parties and entities it governs. These include ensuring that the specified Saab SF340A aircraft are inspected to determine if they fall within the directive's applicability. If they do, the aircraft owners or operators must replace the air recirculation fans as specified in the directive, adhering to the timelines provided. This involves not only the physical replacement of parts but also ensuring that the work is carried out in accordance with the instructions detailed in the SAAB service bulletins. The directive also mandates that any modifications or compliance actions be recorded appropriately to demonstrate adherence to the AD.
Failure to comply with the requirements of this AD can result in significant consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against non-compliance, which could include fines, suspension or revocation of airworthiness certificates, or other regulatory measures. The specific penalties for non-compliance are not detailed in the AD but are governed by the broader Civil Aviation Regulations 1998 and any applicable enforcement policies. Given the safety-critical nature of the directive, non-compliance could potentially lead to severe penalties, both civil and criminal, depending on the circumstances and the extent of the non-compliance.
