AD/B747/15 Amdt 1 - Trailing Edge Flap Track Fuse Bolt - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, as amended by the 2006 legislative instrument F2006B03051, address the ongoing maintenance and safety of civil aviation aircraft, including the Boeing 747 series aeroplanes. This legislative instrument was enacted to ensure that aircraft operations comply with the highest safety standards by setting out detailed regulations and directives. The problem it addresses is the need for continuous safety oversight and improvements in aircraft design and maintenance to prevent accidents and ensure passenger and crew safety. This legislative instrument was enacted by the Parliament of the Commonwealth of Australia and the policy objective is to mandate compliance with safety directives to maintain airworthiness. The specific directive AD/B747/15 Amendment 1, related to the trailing edge flap track fuse bolt inspection and replacement, is a part of the broader regulatory framework aimed at enhancing the safety and reliability of Boeing 747 series aeroplanes.

Scope and Application

The Civil Aviation Regulations 1998, under the jurisdiction of the Civil Aviation Safety Authority (CASA) in Australia, govern various aspects of aviation safety and operations, including the maintenance and airworthiness of aircraft. Specifically, PART 39 - 105 applies to all Boeing 747 series aeroplanes and mandates compliance with Airworthiness Directives (ADs). AD/B747/15 Amendment 1 pertains to the inspection and replacement of the Trailing Edge Flap Track Fuse Bolt for these aeroplanes. This directive applies to all model 747 aeroplanes as listed in Boeing Service Bulletin (SB) 747-57-2206, Revision 1, which supersedes the previous SB 747-57-2177. Compliance with this directive is critical and must be conducted as detailed in the specified Requirement Document, ensuring the continued safety and airworthiness of the affected aircraft within the Australian aviation industry. The scope of this legislation is national, and adherence to these regulations is mandatory for all entities operating Boeing 747 aeroplanes in Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives (ADs), detailing mandatory compliance for certain aircraft models. In this instance, AD/B747/15 Amendment 1 pertains to the Boeing 747 series aeroplanes, focusing on the trailing edge flap track fuse bolt (Section 1). This AD mandates the inspection and replacement of these bolts as per Boeing Service Bulletin 747-57-2206, Revision 1 (Section 2). The applicability of this AD extends to all model 747 aeroplanes listed in the referenced Boeing Service Bulletin (Section 3). Under this AD, the primary obligation for operators of Boeing 747 series aeroplanes is to comply with the requirements outlined in Boeing SB 747-57-2206, Revision 1. This includes conducting thorough inspections of the trailing edge flap track fuse bolts and replacing them as necessary (Section 4). Operators must ensure that these tasks are performed in accordance with the specifications and timelines prescribed by the Civil Aviation Safety Authority (CASA) to maintain the airworthiness of their aircraft (Section 5). Failure to comply with AD/B747/15 Amendment 1 could result in significant consequences. Non-compliance with airworthiness directives can lead to enforcement actions by CASA, which may include administrative penalties (Section 6). The severity of the penalties depends on the nature and extent of the non-compliance, but they can include fines and other civil or criminal sanctions. In extreme cases, CASA may take steps to ground non-compliant aircraft until the necessary inspections and repairs are carried out, which could severely disrupt operations (Section 7).
