AD/LA-4/15 - Auxiliary Fuel System - Placard

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive set of rules governing all aspects of civil aviation within Australia. Specifically, Part 39 - 105 of these regulations, which pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addresses the maintenance and safety of aircraft to ensure public safety and operational efficiency in the aviation industry. One such directive, AD/LA-4/15, pertains to Consolidated Aeronautics, Colonial and LA-4 Series Aeroplanes, aiming to mitigate risks associated with the auxiliary fuel system by mandating clear warnings and operational procedures. This directive was introduced to address specific safety concerns related to the auxiliary fuel system, particularly the prohibition of fuel transfer without first ensuring that the auxiliary tank sumps are free of water, thereby preventing potential issues that could arise from water contamination during operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, governing the operational safety of aircraft within Australia. Under this legislative instrument, the AD/LA-4/15 directive addresses auxiliary fuel systems for Consolidated Aeronautics, Colonial, and LA-4 series aeroplanes. The directive applies to all models LA-4 and LA-4-200 aeroplanes that are equipped with auxiliary fuel tanks as per the Supplemental Type Certificate No. SA 876EA. It mandates either the installation of a specific placard adjacent to the auxiliary tank fuel transfer switches or compliance with FAA AD 76-02-01, Amendment 39-2494. The requirement to install the placard must be fulfilled before 16 April 1976, ensuring that these aircraft meet stringent safety standards to prevent the transfer of water-contaminated fuel from the auxiliary tanks. This directive is part of the broader regulatory framework managed by CASA, which ensures the safety and airworthiness of civil aircraft within Australia.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, addresses the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives, specifically concerning Consolidated Aeronautics, Colonial, and LA-4 Series aeroplanes. AD/LA-4/15 focuses on the auxiliary fuel system and mandates that a placard be installed adjacent to the auxiliary tank fuel transfer switches (sections 1/76). This placard must either state "WARNING AUXILIARY TANK FUEL TRANSFER PROHIBITED UNLESS AUXILIARY TANK SUMPS ARE DRAINED FREE OF WATER AFTER EACH WATER OPERATION" or reference FAA AD 76-02-01, Amendment 39-2494. The requirement is applicable to all LA-4 and LA-4-200 models fitted with auxiliary fuel tanks to Supplemental Type Certificate No. SA 876EA. Operators of LA-4 and LA-4-200 aeroplanes must ensure that the specified placard is installed as per the directive. This installation must occur before 16 April 1976, as stipulated by the regulation. The primary obligation is to prevent the transfer of fuel from the auxiliary tank if it contains water, thereby avoiding potential operational hazards associated with water in the fuel system. This requirement ensures that the aircraft remain airworthy and compliant with safety standards set by CASA. Failure to comply with the placard installation requirement may result in non-compliance with CASA regulations, potentially leading to enforcement actions. While specific penalties are not outlined in the provided text, non-compliance with Civil Aviation Regulations can generally lead to enforcement actions, fines, or other civil penalties. Additionally, if non-compliance results in operational hazards or incidents, it could attract more severe consequences, including criminal charges, depending on the circumstances and the extent of the breach. It is essential for operators to adhere to these directives to maintain the airworthiness of their aircraft and ensure safe operations.
