AD/ELECT/67 - Aerospace Lighting Corporation Cabin Fluorescent Lighting System Components

Overview

The Commonwealth of Australia introduced the Civil Aviation Regulations 1998 to establish and maintain a comprehensive regulatory framework for civil aviation safety in Australia. Enacted by the Australian Parliament, the regulations are designed to ensure the highest standards of safety and airworthiness in the aviation sector. This legislation addresses critical gaps in aviation safety by providing detailed requirements for the certification, operation, and maintenance of aircraft and associated equipment, aiming to prevent accidents and ensure the safety of passengers and crew. The Civil Aviation Safety Authority (CASA) enforces these regulations to maintain safety standards and ensure compliance across the industry. One specific directive under this legislation is AD/ELECT/67, issued to address safety concerns related to cabin fluorescent lighting system components manufactured by Aerospace Lighting Corporation (ALC). The directive targets particular ALC products used in various aircraft models, aiming to prevent incidents of smoke and fire caused by high voltage arcing or overheating. The directive requires inspections and, if necessary, the replacement of certain components to mitigate these risks, ensuring that aircraft remain safe for operation. This directive is a part of CASA's efforts to enforce safety measures and maintain the integrity of aviation safety standards.

Scope and Application

The AD/ELECT/67 Aerospace Lighting Corporation Cabin Fluorescent Lighting System Components 3/96 applies specifically to certain products manufactured by the Aerospace Lighting Corporation (ALC) that are used in the cabin fluorescent lighting systems of various aircraft. This includes lamp connectors with part number 31.85.1.A, Series 66 fluorescent lamps, power units with part numbers TR-991, TR-992, AL-0546, and AL-0514, and power supplies with part numbers 18-95D and AL-0598. These components are used in a wide range of aircraft such as Airbus Industrie A310, Boeing 727, 737, 747, and 757, as well as various models from Raytheon Corporate Jets, Bombardier Canadair, Cessna, Dassault Aviation, Embraer, Gulfstream, Israel Aircraft Industries, Jetstream, Learjet, Saab, and Sikorsky. The Directive mandates inspections and replacements to mitigate risks of smoke, fire, and electrical issues that could impact flight safety. Compliance with the directive requires inspections to be conducted prior to a specified date and replacements to be made if any damage or improper configuration is identified during the inspection or within a defined timeframe after a component failure. The directive provides for certain actions to terminate the repetitive inspection requirement following a component failure. The directive is applicable across Australia in accordance with the Civil Aviation Regulations 1998, and it does not explicitly exclude any particular entities or circumstances, though it is specific to the identified ALC products.

Key Provisions

The primary sections of this legislative instrument (sections 1 and 2) specify the applicable Aerospace Lighting Corporation (ALC) products and require inspection and replacement of specific components in cabin fluorescent lighting systems. Section 1 outlines the products affected by this directive, which include Lamp Connectors part number (P/N) 31.85.1.A; Series 66 fluorescent lamps; Power Units P/N TR-991, TR-992, AL-0546 and AL-0514; and Power Supplies P/N 18-95D and AL-0598. These products are installed in various aircraft models, such as Airbus, Boeing, and Bombardier Canadair series. Section 2 mandates that the cabin fluorescent lighting system must be inspected in accordance with ALC Information Bulletin IB 90-001 dated 15 August 1992, Part IV, sub-paragraphs B.1, 2, 3, 5, 6 and 7. Additionally, any damaged or improperly configured parts must be removed and replaced following the procedures in Part IV sub-paragraphs B.4, 8 and 9 of IB 90-001. The obligations imposed by this Act on the parties or entities it governs include conducting the required inspections and replacements of the specified components. For Requirement 1, inspections must be completed before 29 April 1996 if not previously accomplished in accordance with AD/ELECT/56. For Requirement 2, inspections must be performed before further flight if any parts are found to be damaged or improperly configured during the inspection or within five flights or 10 hours in service, whichever occurs first, following a component failure. The replacement of specified ALC parts in accordance with the provided instructions constitutes the terminating action for the repetitive inspection requirement. Failure to comply with the requirements of this directive may result in civil or criminal consequences. While specific penalties are not mentioned in the text, the directive emphasises the importance of these actions in preventing smoke, fire, and possible electric shock or electromagnetic interference to flight-critical or essential systems. Non-compliance could potentially lead to safety risks and legal repercussions for the parties involved in the maintenance and operation of the affected aircraft.
