Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an airworthiness directive concerning the Embraer EMB-120 (Brasilia) Series Aeroplanes, with the directive number AD/EMB-120/4. This directive was introduced to address a safety concern identified with the plug-in table stowage assembly, which has the potential to impede the proper operation of the rear partition blow-out panel between the cargo and passenger compartments. The directive mandates compliance with the technical requirements outlined in Brazil's Civil Aviation Authority AD 91-10-01 Amdt 39-688, and references Embraer Service Bulletin 120-025-0163 for further details. The regulation applies to a specified list of Embraer EMB-120 aircraft with particular serial numbers, and compliance is required in accordance with the amended effective date of 12 January 1991 for aircraft registered in Australia. The objective of this directive is to ensure the airworthiness and safety of the affected aircraft by correcting the identified issue.
This legislative instrument was enacted by the Commonwealth of Australia and is administered by the Civil Aviation Safety Authority (CASA). The policy objective underpinning this directive is to maintain the highest standards of safety in civil aviation by implementing necessary measures to address identified safety risks. By enforcing compliance with the specified technical requirements, CASA aims to prevent potential hazards and ensure that the affected aircraft meet the necessary safety standards for operation in Australian airspace.
Scope and Application
The Embraer EMB-120 (Brasilia) Series Aeroplanes AD/EMB-120/4 Table Stowage regulation applies specifically to certain models of the Embraer EMB-120 series aeroplanes, identified by their serial numbers, as listed in the legislation. This regulation mandates compliance with the technical requirements of Brazil's Civil Aviation Authority AD 91-10-01 Amdt 39-688, which addresses the potential operational issues caused by the plug-in table stowage assembly. The directive is applicable to Australian registered aircraft and requires adherence to the specified requirements with an effective date of 12 January 1991. Embraer Service Bulletin 120-025-0163 provides additional guidance in this matter. The regulation is issued under the Civil Aviation Regulations 1998 and forms part of the broader legislative framework governing civil aviation safety in Australia. This regulation does not explicitly state any exclusions or exemptions but is narrowly focused on the specified models to mitigate risks associated with the table stowage assembly. Subordinate instruments may further detail compliance requirements and enforcement measures.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39, Section 105, mandate specific airworthiness directives for certain models of aeroplanes, including the Embraer EMB-120 (Brasilia) series. This regulation applies to the specific serial numbers listed, requiring compliance with the technical requirements set out in Brazil's Civil Aviation Authority (CTA) AD 91-10-01 Amendment 39-688. This is further supported by Embraer Service Bulletin 120-025-0163, which provides additional details on the required modifications. The regulation was revised to have an effective date of 12 January 1991 for Australian registered aircraft, ensuring that these modifications are implemented to maintain safety standards.
The obligations imposed by these regulations on the relevant parties include ensuring that the aircraft meet the specified technical requirements. Owners and operators of the affected Embraer EMB-120 series aeroplanes must ensure that the plug-in table stowage assembly is modified or replaced as per the directives. This involves adhering to the technical specifications outlined in the Brazil CTA AD 91-10-01 Amendment 39-688, and implementing any additional instructions from Embraer's Service Bulletin. The compliance must be documented and verified to ensure that the aircraft are airworthy and safe for operation.
Failure to comply with the airworthiness directives set forth in this regulation can result in severe consequences. Operators who do not adhere to the specified modifications may face civil penalties, including fines and potential grounding of the aircraft. The severity of the penalties can vary based on the extent of non-compliance and the risk posed to flight safety. Additionally, non-compliance can lead to criminal charges if it is determined that the failure to adhere to these regulations directly contributed to an aviation incident or accident. The potential penalties underscore the importance of strict adherence to these directives to ensure the safety and airworthiness of the aircraft in question.
