Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide comprehensive rules and standards governing civil aviation safety in Australia, aiming to ensure the highest level of safety and efficiency within the civil aviation sector. Specifically, Part 39 - 105 of these regulations, focusing on Airworthiness Directives, was introduced to address safety concerns and rectify unsafe conditions related to aircraft and aeronautical products. These directives are issued by the Civil Aviation Safety Authority (CASA), which acts as the delegate of the Commonwealth of Australia, ensuring that all civil aviation activities adhere to stringent safety standards. The policy objective behind these directives is to mitigate risks and maintain the airworthiness of aircraft by enforcing timely and necessary corrective actions, as illustrated by the Airworthiness Directive AD/DHC-8/90 concerning the inspection of fuel vent and scavenge line fittings in Bombardier (Boeing Canada/De Havilland) DHC-8 Series Aeroplanes.
Scope and Application
This Airworthiness Directive issued under the Civil Aviation Regulations 1998 applies to specific Bombardier (Boeing Canada/De Havilland) DHC-8 series aeroplanes, namely models 102, 103, 106, 201, 202, 301, 311, 314 and 315 within the serial number range of 003 through 586 inclusive. The directive mandates an inspection of the fuel vent and scavenge line fittings to address a potential safety issue identified, specifically the risk of a contact condition between the lockwire pigtail of a Wiggins fitting and a stiffener on the inside surface of a fuel access cover which could act as an ignition source in the event of a lightning strike. The requirements for the action to be taken are detailed in Transport Canada AD CF-2002-44, which has been adopted with a revised effective date of 23 January 2003. The directive was issued by a delegate of the Civil Aviation Safety Authority and became effective on 23 January 2003. The scope and application of this AD is national and is subject to the regulatory framework of the Commonwealth of Australia.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 (CAR 1998) pertain to the requirements for Bombardier (Boeing Canada/De Havilland) DHC-8 Series Aeroplanes, specifically those in the models and serial numbers specified (section 1). This AD mandates that corrective actions be taken to address a potential unsafe condition related to the fuel vent and scavenge line fittings, as outlined in Transport Canada AD CF-2002-44 (section 2). The directive becomes effective on 23 January 2003 (section 3).
The obligations and requirements imposed by this AD on the relevant parties include conducting an inspection and taking corrective action on the fuel vent and scavenge line fittings of the specified DHC-8 models and serial numbers, following the instructions provided in Transport Canada AD CF-2002-44. This inspection and corrective action must be carried out by the specified compliance date to ensure the safety and airworthiness of the aircraft. It is essential for the operators and maintenance personnel to adhere to the instructions detailed in the referenced Transport Canada AD to address the identified unsafe condition effectively.
There are no explicit offences, penalties, or civil/criminal consequences mentioned in the text for non-compliance with this AD. However, failing to comply with an Airworthiness Directive can result in the aircraft being deemed unairworthy, which could lead to serious safety implications and potential legal consequences for the operators or owners. While the specific maximum penalties are not stated in this text, non-compliance with ADs can result in enforcement actions by the Civil Aviation Safety Authority (CASA), including grounding the aircraft, fines, or other regulatory actions.
