Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, which includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, was enacted to ensure the safety and airworthiness of aircraft operating in Australian airspace. The regulations were introduced to address safety gaps and ensure compliance with international standards. The Act was established by the Parliament of the Commonwealth of Australia and aims to provide clear, enforceable rules that protect the public and promote safe aviation practices. The Civil Aviation Regulations 1998, through the Airworthiness Directives, mandate that certain aircraft models, such as the British Aerospace BAe 146 series, comply with specific safety measures to mitigate identified risks, such as potential leaks in engine-driven pump case drain couplings, which were highlighted during fire resistance tests. Compliance with these directives is essential to ensure the continued safety and reliability of the aircraft in operation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). This particular directive, AD/BAe 146/49, concerns the engine driven pump case drain coupling on British Aerospace BAe 146 series aeroplanes. The directive applies to specific models and serial numbers of the BAe 146 series, including the BAe 146-100 or -100A series with serial numbers ranging from E1002 through E1199, the BAe 146-200 or -200A series with serial numbers from E2008 through E2204 or E2210 through E2220, and the BAe 146-300 or -300A series with serial numbers from E3001 through E3219 or E3222. Compliance with the directive is mandatory, requiring adherence to BAe Mandatory Service Bulletin SB.29-31 01339A Revision 1 by the specified deadline of 31 July 1994. The directive addresses a critical safety concern identified by the manufacturer during a fire resistance test, where the engine driven pump case drain lines exhibited leakage. This requirement ensures that all specified aircraft meet necessary safety standards to prevent potential hazards during operation.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39, specifically in Section 105, address the safety and airworthiness of aircraft. The regulation in question pertains to British Aerospace BAe 146 Series Aeroplanes and is detailed in AD/BAe 146/49. This Airworthiness Directive (AD) is focused on the Engine Driven Pump (EDP) Case Drain Coupling of certain BAe 146 models. The directive mandates that specific action be taken in accordance with BAe Mandatory Service Bulletin SB.29-31 01339A Revision 1, unless such action has already been performed (Section 39-105). This requirement is linked to FAA AD 93-24-05 Amendment 39-8754, further reinforcing its importance.
This AD applies to all BAe 146-100 or -100A series aeroplanes with serial numbers ranging from E1002 to E1199, BAe 146-200 or -200A series with serial numbers E2008 through E2204 or E2210 through E2220, and BAe 146-300 or -300A series with serial numbers E3001 through E3219 or E3222. The directive is aimed at addressing a potential safety issue identified during a fire resistance test, where the EDP case drain lines were found to leak. Compliance with this directive is mandatory, and all affected aircraft must adhere to the specified actions by 31 July 1994.
Entities governed by this Act, particularly aircraft operators and maintenance organisations, must ensure that the specified action is carried out on the relevant BAe 146 models. This involves following the detailed instructions provided in the BAe Mandatory Service Bulletin SB.29-31 01339A Revision 1. Failure to comply with these requirements could lead to significant safety risks and non-compliance with regulatory standards. The directive underscores the importance of regular maintenance checks and adherence to manufacturer-provided service bulletins to ensure the continued airworthiness of the aircraft.
Failure to comply with the provisions of this AD could result in severe consequences. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against non-compliant entities. These actions could include the issuance of directives, suspension or revocation of airworthiness certificates, and other regulatory penalties. Non-compliance not only poses a risk to the safety of the aircraft but could also lead to financial penalties and reputational damage for the operators. The seriousness of these consequences highlights the critical nature of adhering to the specified safety directives.
