AD/G159/43 Amdt 1 - Fluorescent Lighting Installations Incorporating Series 66 Lamps

Overview

The Civil Aviation Orders, enacted by the Civil Aviation Safety Authority in 1990, were established to ensure safety and regulatory compliance within the Australian aviation industry. Specifically, Part 105 of the Civil Aviation Orders addresses airworthiness directives, which are legal mandates issued to correct safety issues in aircraft. The AD/G159/43 Amendment 1 pertains to the Gulfstream (Grumman) G.159 series aeroplanes, focusing on fluorescent lighting installations incorporating Series "66" lamps. This legislative instrument aims to mitigate potential fire hazards associated with these lighting systems, following an incident reported by Gulfstream where an inflight fire occurred in the area of the installed fluorescent lighting. The policy objective is to ensure compliance with Gulfstream Aerospace Customer Bulletin No. 333 and Aerospace Lighting Corp Information Bulletin 89-001 to maintain the safety standards of the aircraft.

Scope and Application

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives AD/G159/43 Amendment 1, pertains to all Gulfstream I aircraft, which must adhere to the safety measures outlined in Gulfstream Aerospace Customer Bulletin No. 333. This includes performing required actions 1, 2, 3, and 4.1 to address potential issues with the fluorescent lighting installations incorporating Series "66" lamps, as referenced in Aerospace Lighting Corp Information Bulletin 89-001. The directive was issued following a reported in-flight fire in the area of the installed fluorescent lighting, although the exact cause remains undetermined. Compliance with these measures is mandatory for all affected aircraft, with a compliance deadline set prior to 30 December 1989. This directive is applicable across the Commonwealth of Australia, enforcing safety standards set by the Civil Aviation Safety Authority. The Act applies to all entities operating Gulfstream I aircraft within the jurisdiction of the Commonwealth, ensuring adherence to specified safety protocols to mitigate potential hazards. There are no stated exclusions or exemptions within this directive, and its application is strictly enforced through subordinate instruments as necessary.

Key Provisions

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, outlines the requirements for the Gulfstream (Grumman) G.159 series aeroplanes, including the Gulfstream I aircraft (AD/G159/43). This directive mandates that all Gulfstream I aircraft must comply with Gulfstream Aerospace Customer Bulletin No. 333, focusing on required actions 1, 2, 3, and 4.1. This compliance is essential to address potential inflight fire risks in the area of the installed fluorescent lighting. Additionally, Aerospace Lighting Corp Information Bulletin 89-001 provides further relevant information. The directive applies to aircraft that must be compliant prior to 30 December 1989, following Gulfstream's advisory on an inflight fire, although the exact cause remains unknown. Entities governed by these provisions must ensure that the Gulfstream I aircraft undergo the specified modifications as outlined in Gulfstream Aerospace Customer Bulletin No. 333. This includes carrying out actions 1, 2, 3, and 4.1, which are designed to mitigate the risk of inflight fires in the fluorescent lighting area. The requirement to act on these directives is clear and unambiguous, necessitating strict adherence to the specified actions. The compliance date of 30 December 1989 is a non-negotiable deadline for all affected aircraft to meet these safety standards. Failure to comply with the provisions of AD/G159/43 can result in severe consequences. The Civil Aviation Orders impose significant obligations on operators to ensure their aircraft meet the safety standards set out in the directive. Non-compliance may lead to civil or criminal penalties, which could include fines and other sanctions. The exact penalties are not specified in the provided text, but they could be substantial given the safety-critical nature of the directive. Ensuring adherence to the requirements is not only a legal obligation but also a critical measure to protect the safety of all persons on board. In summary, the AD/G159/43 directive is a critical safety measure for Gulfstream I aircraft, mandating specific actions to address potential fire risks in the fluorescent lighting area. Compliance with this directive is mandatory, and failure to adhere to the specified actions could result in severe legal consequences. The directive underscores the importance of maintaining high safety standards in civil aviation and the serious repercussions that come with neglecting these essential safety requirements.
