AD/AC-112/5 Amdt 1 - Fuel Selector Valve - Inspection and Replacement

Overview

The Civil Aviation Safety Authority (CASA) introduced the Civil Aviation Regulations 1998, specifically Part 39, to establish comprehensive safety standards within Australia's aviation industry, aiming to protect the public and ensure the safe operation of aircraft. This legislation was enacted to address the need for stringent and consistent safety measures across the aviation sector, encompassing areas such as aircraft design, maintenance, and operational protocols. The overarching policy objective is to maintain and enhance the safety of civil aviation, ensuring that all stakeholders adhere to high standards that mitigate risks associated with air travel. The authority granted by this Act to CASA enables the enforcement of safety directives, including specific amendments like AD/AC-112/5 Amendment 1, which pertains to the inspection and replacement of fuel selector valves in certain Gulfstream (Rockwell) 112 Series aeroplanes, thereby ensuring continued airworthiness and operational safety. This legislative instrument, identified as F2006B02189, is a regulatory measure under the Civil Aviation Act 1988, administered by CASA. It targets specific aircraft models with serial numbers within defined ranges, mandating compliance within a specified timeframe to address potential safety hazards associated with fuel selector valve malfunctions. The directive ensures that the identified aircraft meet necessary safety standards, contributing to the overarching goal of maintaining the highest levels of safety in civil aviation. CASA's role in enforcing these regulations is pivotal in safeguarding the aviation industry and the public from potential risks related to aircraft operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, governing the operational safety standards for aircraft registered within Australia. This legislative instrument applies to Gulfstream (Rockwell) 112 Series aeroplanes, with particular focus on models 112 and 112TC, serial numbers ranging from 3 to 106 and 108 to 489 for the 112, and from 13002 to 13108 for the 112TC. These regulations mandate that compliance with AD/AC-112/5 Amendment 1, which addresses the inspection and replacement of fuel selector valves, must be achieved within 100 hours of the aircraft's time in service after 31 May 1978. Compliance with the preceding issue of this directive is acknowledged as fulfilling the requirements of the current issue. The regulations cover both domestic and international operations, ensuring that all aircraft meeting the specified criteria adhere to the outlined safety standards. This directive extends its reach through subordinate instruments that may further specify compliance details and operational protocols.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the maintenance and airworthiness of aircraft within Australia. In this instance, the legislation pertains to Gulfstream (Rockwell) 112 Series Aeroplanes, with the focus on the fuel selector valve. This is detailed in AD/AC-112/5 Amendment 1, which mandates the inspection and replacement of the fuel selector valve (section 1/77). The directive applies to specific models of the Gulfstream 112 Series, namely those with serial numbers within the specified ranges (section Applicability). The requirement is for compliance to be achieved within 100 hours of the aeroplane’s time in service following 31 May 1978. It is worth noting that compliance with the previous version of this directive will satisfy the requirements of this current version (section Note). The obligations under this directive require the aircraft operators to ensure that the specified fuel selector valves are inspected and replaced if necessary, within the stipulated timeframe. This involves adhering to the procedures outlined in Rockwell International Service Bulletin No. SB-112-44A, which provides detailed guidance on how to perform the inspection and replacement. The operators must maintain records of compliance to demonstrate adherence to the directive, ensuring that all required maintenance actions are documented and verified by appropriately qualified personnel. Failure to comply with these airworthiness directives can result in severe consequences. Non-compliance could lead to the grounding of the aircraft until the required maintenance is performed, potentially causing significant operational disruptions. Furthermore, regulatory authorities have the power to impose penalties for non-compliance. These penalties can include fines, which are determined based on the severity and frequency of the breach. In some cases, serious non-compliance could lead to more severe civil or even criminal penalties, depending on the circumstances and the impact of the non-compliance on aviation safety. The exact penalties are not specified in the directive but are governed by the broader provisions of the Civil Aviation Act 1988 and associated regulations.
