Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as the primary legislative instrument governing civil aviation safety in the country. This legislation includes a specific section, Part 39 - 105, which deals with the Authority Schedule of Airworthiness Directives, including requirements for the Embraer EMB-110 (Bandeirante) Series Aeroplanes. The problem this legislation addresses is the potential for wear in the main and nose landing gear wiring of the EMB-110 aircraft, which could lead to open and/or short circuits, causing erratic indications and uncommanded operation of the landing gear, thereby compromising flight safety. The policy objective of these regulations is to ensure that all applicable aircraft are inspected and maintained according to specified intervals to prevent such safety issues.
The Embraer EMB-110 series aeroplanes, under AD/EMB-110/42, must adhere to the directive requiring an inspection of the main and nose landing gear wiring in accordance with Embraer SB 110-32-052R3, with references to the Brazilian AD 82-10-02R1. The compliance requirements mandate that inspections must be conducted within 25 hours from a specified date and then at intervals not exceeding 600 hours or three months to maintain airworthiness and ensure safe operations.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the airworthiness directives for the Embraer EMB-110 (Bandeirante) Series Aeroplanes, focusing on a critical maintenance requirement detailed in AD/EMB-110/42. This legislation applies to all EMB-110 aircraft within the Commonwealth of Australia, encompassing both private and commercial operations. The requirement mandates that an inspection of the main and nose landing gear wiring be conducted in accordance with Embraer Service Bulletin 110-32-052R3, with a direct reference to Brazilian Airworthiness Directive 82-10-02R1. Compliance with this directive is critical to ensure the continued safe operation of the aircraft, as the wiring in these landing gear assemblies can wear over time, potentially leading to open or short circuits that could result in erroneous landing gear indications or uncommanded operation. The inspection must be performed within 25 hours of service time from 28 December 1989, and thereafter at intervals not exceeding 600 hours of service time or three months, whichever comes first. This regulation does not specify any exclusions or exemptions but is intended to maintain the high safety standards set forth by the Civil Aviation Safety Authority.
Key Provisions
The primary sections of the Embraer EMB-110 (Bandeirante) Series Aeroplanes AD/EMB-110/42 Undercarriage Wiring Inspection regulation (section 1) mandate that all model EMB-110 aircraft must undergo specific inspections of the main and nose landing gear wiring. The inspection must be carried out in accordance with Embraer Service Bulletin (SB) 110-32-052R3, with reference to Brazilian AD 82-10-02R1. The regulation stipulates that these inspections must be completed within 25 hours of the aircraft's time in service from 28 December 1989, and thereafter, at intervals not exceeding 600 hours of time in service or three months.
Operators of the Embraer EMB-110 aircraft are obligated to ensure that the specified inspections are performed by certified personnel or entities as per the regulations outlined in Embraer SB 110-32-052R3. These inspections are crucial to detect any wear and tear in the undercarriage wiring, which, if left unchecked, can lead to open or short circuits, resulting in erratic indications or uncommanded operation of the landing gear. Compliance with these inspections is mandatory and must be meticulously documented and maintained as part of the aircraft's service records.
Failure to comply with the inspection requirements outlined in the regulation can lead to significant consequences. Firstly, non-compliance may result in the aircraft being deemed unairworthy, which can prevent it from operating until the required inspections are completed and any identified issues are resolved. Additionally, there may be civil penalties imposed for not adhering to the stipulated inspection intervals. According to the Civil Aviation Safety Authority regulations, such non-compliance could incur fines up to a specified maximum amount. Furthermore, there could be criminal liabilities if the non-compliance is found to have contributed to an aviation incident or accident, potentially leading to prosecution under the relevant criminal statutes.
The severity of the penalties underscores the importance of strict adherence to the inspection requirements, highlighting the need for operators to maintain rigorous records and ensure all inspections are timely and accurately performed. This regulatory framework is designed to maintain the highest safety standards in civil aviation, ensuring the continued airworthiness and safety of the Embraer EMB-110 series aeroplanes.
