AD/MSR/4 - L/H Fuel Supply Hose - Replacement Fuel Gauge Vent - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, govern the safety and operation of civil aviation within Australia. This legislation, overseen by the Civil Aviation Safety Authority (CASA), was introduced to establish a comprehensive regulatory framework aimed at ensuring the safety of aircraft and the protection of individuals in and around aircraft operations. Specifically, Part 39 - 105 of the Civil Aviation Regulations addresses Airworthiness Directives, which are legally enforceable rules related to the design, production, maintenance, and operation of aircraft. These directives ensure that all aircraft meet stringent safety standards, thereby mitigating risks associated with aviation activities. One particular Airworthiness Directive, AD/MSR/4 L/H, pertains to Aerospatiale Rallye Series Aeroplanes, mandating the replacement of fuel supply hoses and modifications to fuel gauge vents for aircraft with specific serial numbers. This directive is part of the broader legislative objective to maintain and enhance the airworthiness of aircraft, thereby preventing potential hazards and ensuring the safety of passengers and crew. The directive is issued by CASA and must be complied with immediately, as specified in Rallye SB No. 9.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority, apply to the Aerospatiale Rallye Series Aeroplanes, mandating compliance with the Airworthiness Directive AD/MSR/4. This directive addresses the replacement of fuel supply hoses and modifications to the fuel gauge vent for aircraft with serial numbers within the range of 1 to 100 for hose replacement and 1 to 107 for vent modifications. The regulations are applicable to all aircraft falling within these serial number ranges, ensuring that both the replacement of fuel supply hoses and the modification of the fuel gauge vent are completed without delay. These provisions are intended to enhance the airworthiness and safety of the specified aircraft, thereby falling under the jurisdiction of the Commonwealth of Australia. The scope of the directive is limited to the specific serial numbers mentioned, with no stated exclusions or exemptions, and compliance must be achieved as soon as practicable. The detailed requirements and procedures for compliance are outlined in Rallye SB No. 9.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, establish specific safety directives aimed at ensuring the airworthiness of aircraft, particularly those of the Aerospatiale Rallye series. One of these directives, AD/MSR/4, pertains to the fuel supply hose and the modification of the fuel gauge vent. This directive applies to aircraft with serial numbers ranging from 1 to 100 for the fuel supply hose and from 1 to 107 for the fuel gauge vent modification (AD/MSR/4). The relevant document for compliance is Rallye SB No. 9, which mandates immediate compliance to ensure safety. The primary obligations imposed by this directive require that all affected aircraft undergo the specified modifications without delay. Specifically, aircraft with serial numbers 1 to 100 must replace the fuel supply hose, while those with serial numbers 1 to 107 must have the fuel gauge vent modified. These modifications are critical to maintaining the structural integrity and operational safety of the aircraft. The directive ensures that all changes are carried out in accordance with the detailed specifications provided in Rallye SB No. 9. Failure to comply with the provisions of AD/MSR/4 can result in serious safety risks, including potential fuel leaks or gauge inaccuracies, which can compromise the safety of flight operations. The regulations impose significant obligations on aircraft owners and operators to ensure that these modifications are completed promptly and correctly. Non-compliance with these directives can lead to enforcement actions, as the regulations are designed to protect public safety and ensure the airworthiness of aircraft. Under the Civil Aviation Regulations 1998, violations of the specified airworthiness directives can result in substantial penalties. The severity of the penalties depends on the nature and extent of the non-compliance, but they may include fines and potential grounding of the affected aircraft until compliance is achieved. The precise penalties are outlined in other sections of the Civil Aviation Act and related regulations, but the overarching goal is to enforce strict adherence to safety standards to prevent accidents and ensure the safety of all passengers and crew.
