Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, address various safety standards and operational requirements for civil aviation. Specifically, Part 39 of the Regulations, which deals with airworthiness directives, includes AD/B747/125 concerning the evacuation slide/raft regulators for Boeing 747 series aeroplanes. This directive was introduced to address the problem of certain evacuation slide/rafts failing to inflate immediately upon deployment, a safety issue identified by the Federal Aviation Administration (FAA) in relation to regulators installed on affected aircraft. The policy objective is to ensure compliance with safety standards by modifying the regulators in accordance with specified service bulletins, thereby enhancing the safety of passengers during emergency evacuations. The requirement to comply with this directive was to be met prior to 26 November 1996.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Boeing 747 Series Aeroplanes, apply to operators of Boeing 747-100, -200, and -300 series aircraft that are equipped with specific BFGoodrich evacuation slides/rafts and regulators as outlined in BFGoodrich Service Bulletin 4A3221-25-250. This legislation mandates that these aircraft must modify the affected regulators to prevent issues such as delays in the inflation of evacuation slides/rafts upon deployment, which could potentially compromise safety during emergency evacuations. The requirement to comply with these modifications must be met before 26 November 1996, as referenced by the Federal Aviation Administration (FAA) AD 93-20-04 Amendment 39-8712. The scope of this legislation is national, applying across all jurisdictions within Australia, ensuring a consistent safety standard for civil aviation. There are no stated exclusions or exemptions in this particular directive, and compliance is non-negotiable to maintain airworthiness and safety.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, concerning the Boeing 747 series aeroplanes, focus on the Airworthiness Directive (AD) AD/B747/125 regarding the evacuation slide/raft regulator. Section (1) identifies the applicability of the directive to Boeing 747-100, -200, and -300 series aircraft equipped with specific BFGoodrich evacuation slides/rafts and regulators. Section (2) details the requirement to modify the affected regulators as per BFGoodrich Service Bulletin 4A3221-25-250. The directive references FAA AD 93-20-04 Amdt 39-8712 for further guidance. Section (3) specifies that compliance with these modifications must be achieved before 26 November 1996. The directive was issued due to reports that regulators on these aircraft had a design flaw similar to those on other transport category aircraft, which had caused evacuation slide/rafts to fail to inflate immediately upon deployment. The obligations imposed by this Act on the parties or entities it governs are primarily centred around ensuring the safety and airworthiness of the specified Boeing 747 series aircraft. Owners and operators of the affected aircraft must comply with the modification requirements outlined in the directive. This includes sourcing the necessary components and ensuring that certified technicians carry out the modifications as per the BFGoodrich Service Bulletin 4A3221-25-250. These modifications are mandatory and must be completed before the specified compliance date to ensure that the evacuation slide/rafts operate as intended during an emergency. The directive underscores the importance of timely and accurate compliance to prevent potential safety hazards during evacuations. In terms of the consequences for non-compliance, the Civil Aviation Regulations 1998 impose significant penalties and legal ramifications. Failure to adhere to the airworthiness directive can result in serious safety risks, and thus, the Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions. These can include the issuance of fines, suspension or revocation of airworthiness certificates, and potential criminal charges for individuals or corporations found in breach of the regulations. The maximum penalties are not explicitly stated in the text but are generally severe, reflecting the critical nature of ensuring aircraft safety. Non-compliance can also lead to operational restrictions and increased scrutiny from regulatory bodies, potentially impacting the reputation and reliability of the airline or operator.
