AD/IAI-W/5 - Galley Electrical Wiring - Inspection and Re-Routing

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive framework for the regulation of civil aviation in Australia. One particular legislative instrument under this act, F2006B10805, addresses safety concerns related to specific aircraft models. This instrument, part of the Schedule of Airworthiness Directives, was introduced to ensure that specific aircraft types meet safety standards and mitigate risks associated with known issues. The problem or gap it addresses is the safety risk posed by electrical faults in the galley area of certain Israel Aircraft Industries 1123 and 1124 (Westwind) Series Aeroplanes. The policy objective is to enhance aviation safety by requiring specific inspections and re-routing of electrical wiring in the affected aircraft to prevent electrical fires caused by short circuits. The Civil Aviation Safety Authority, as part of its regulatory function, issued this directive to mandate inspections and corrective actions on the electrical wiring in the galleys of Westwind Series aeroplanes with specific serial numbers. This action aims to eliminate the risk of electrical failures leading to significant in-flight incidents. The directive follows a documented safety bulletin and references a corresponding Federal Aviation Administration directive, highlighting a collaborative approach to aviation safety between Australia and international bodies. Compliance with these regulations is crucial for maintaining airworthiness and ensuring the safety of passengers and crew.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, issued by the Civil Aviation Safety Authority, apply to the Westwind Series aeroplanes manufactured by Israel Aircraft Industries, serial numbers 239 to 298, with certain exclusions for serial numbers 241, 252, 257, 261, 264, 265, 290, 294, 295, and 297. This legislation mandates inspection and re-routing of the galley electrical wiring in these aircraft to mitigate the risk of electrical failures and fires, following an incident reported by the Federal Aviation Administration where such a failure occurred due to a galley container causing a short circuit. The requirement is jurisdictional across the Commonwealth of Australia and is enforced to ensure the safety of civil aviation operations within the country. Compliance with these directives is essential, with part one requiring action within 10 hours of time in service after 11 November 1980, and part two needing to be completed as soon as practicable, but no later than 100 hours time in service after the same date. This regulation does not specify any exclusions beyond the listed serial numbers and relies on subordinate instruments for further detail and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains the Airworthiness Directives for the Israel Aircraft Industries (IAI) 1123 and 1124 (Westwind) Series Aeroplanes. The directive AD/IAI-W/5 addresses the galley electrical wiring, requiring an inspection and re-routing (12/80). This directive applies to Westwind Series Serial Numbers 239 to 298, excluding 241, 252, 257, 261, 264, 265, 290, 294, 295, and 297 (Applicability). The specific document referenced is IAI 1124-Westwind Service Bulletin No. WW-24-20 (24-03), which also notes that the Federal Aviation Administration (FAA) has issued a similar directive, AD No. 80-19-15 (Document and Note). The obligations under this directive require compliance in two parts. The first part must be completed within 10 hours of time in service after 11 November 1980. The second part must be accomplished as soon as practicable but no later than 100 hours of time in service following the same date (Compliance). The directive was issued due to an incident where a hot liquid container in the galley caused a fire by creating an electrical short circuit with the wiring (Background). Failure to comply with the requirements of this directive could result in significant safety risks. Although the specific penalties for non-compliance are not detailed within the directive itself, non-compliance with Civil Aviation Regulations can generally lead to severe consequences. This may include administrative actions, enforcement actions by the Civil Aviation Safety Authority (CASA), or potential criminal charges depending on the severity of the breach and its impact on safety. The penalties can vary, but they may include fines and other sanctions that are prescribed under the Civil Aviation Act 1988 and related regulations. The seriousness of the safety issue addressed by this directive underscores the importance of strict adherence to the outlined compliance timelines.
