Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted by the Parliament of the Commonwealth of Australia to address safety concerns in civil aviation. The aim of this regulation is to ensure the airworthiness of aircraft by mandating adherence to specific safety directives and standards. The Embraer EMB-110 (Bandeirante) Series Aeroplanes AD/EMB-110/41, which deals with engine electrical connectors, was introduced to rectify issues related to the reliability of engine systems due to out-of-specification rear insulators on certain electrical connectors. The policy objective is to enhance safety by ensuring that all aircraft comply with the specified safety directives, thereby mitigating risks associated with potential electrical system failures.
This legislative instrument is part of a broader framework designed to maintain high safety standards in the aviation industry. By referencing Embraer Service Bulletin SB 110-071-0023 and aligning with Brazilian AD 88-11-01, the regulation ensures that the necessary corrective actions are implemented to address the identified safety concerns. Compliance with these directives is mandatory for specified serial numbers of the Embraer EMB-110 aircraft to ensure the continued safe operation of these aeroplanes.
Scope and Application
The Embraer EMB-110 (Bandeirante) Series Aeroplanes Airworthiness Directive (AD/EMB-110/41) applies specifically to all EMB-110 models with serial numbers (S/Nos) ranging from 110001 through 110444 that are compliant with Service Bulletin (SB) 110-071-0009/1, as well as those with S/Nos 110445 through 110478. This regulation mandates compliance with the requirements set out in Embraer SB 110-071-0023, which addresses issues with rear insulators on certain engine electrical connectors that are out of specification, potentially impacting the reliability of various engine systems. The directive aims to ensure the continued airworthiness of these aircraft by mandating corrective actions. The geographic reach of this regulation is national, as it pertains to aircraft operating within Australia, and it is enforced by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998. This legislation does not explicitly state exclusions or exemptions, and compliance must be achieved prior to the specified date of 9 August 1989. The directive references Brazilian AD 88-11-01, indicating a cross-jurisdictional recognition of the issue and solution.
Key Provisions
The Embraer EMB-110 (Bandeirante) Series Aeroplanes Airworthiness Directive (AD/EMB-110/41) is a regulatory requirement set out under the Civil Aviation Regulations 1998 (CAR 1998). Specifically, it pertains to the engine electrical connectors for certain model EMB-110 aeroplanes, as detailed in Part 39, Schedule of Airworthiness Directives. The directive applies to all model EMB-110 aeroplanes with serial numbers (S/Nos) ranging from 110001 to 110444 that comply with Service Bulletin (SB) 110-071-0009/1, as well as those with S/Nos 110445 to 110478. The directive mandates that actions be taken in accordance with Embraer SB 110-071-0023, with reference to Brazilian AD 88-11-01. The directive aims to address an issue where certain electrical connectors installed to the engine "C" flange have rear insulators that are out of specification, which could potentially affect the reliability of various engine systems.
The AD/EMB-110/41 imposes obligations on the operators of affected aircraft to ensure compliance with the specified actions outlined in Embraer SB 110-071-0023. This includes verifying that the electrical connectors' rear insulators meet the required specifications and taking corrective actions if necessary. The directive also requires that compliance with the directive be achieved before 9 August 1989. Operators must ensure that all necessary inspections and repairs are completed within this timeframe to maintain the airworthiness of the aircraft.
Failure to comply with the provisions of the AD/EMB-110/41 may result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against operators who do not adhere to the requirements of the directive. Potential penalties for non-compliance can include fines, enforcement notices, and in severe cases, the grounding of the aircraft until the required actions are taken. The specific penalties depend on the severity and frequency of the non-compliance, but they are designed to ensure that all affected aircraft meet the necessary safety standards to protect the public and maintain the integrity of the aviation system.
In summary, the AD/EMB-110/41 is a critical regulation that mandates specific actions to address an identified safety issue with the engine electrical connectors on certain Embraer EMB-110 aeroplanes. Operators of affected aircraft must ensure compliance with the directive by taking the necessary corrective actions as specified in Embraer SB 110-071-0023, with a compliance deadline of 9 August 1989. Non-compliance with this directive can result in serious penalties, underscoring the importance of adhering to the regulatory requirements to maintain the safety and airworthiness of the aircraft.
