AD/B747/210 - Aileron Cable System

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address the need for stringent safety standards in civil aviation, particularly in relation to the maintenance and inspection of aircraft. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 provides a schedule of airworthiness directives to ensure that aircraft meet required safety standards. The problem this legislation aims to address is the risk of in-flight mechanical failures due to issues such as improper installation and wear of critical components. This is exemplified by Airworthiness Directive AD/B747/210 concerning Boeing 747 series aeroplanes, which mandates inspections of aileron cables and their markers following a reported incident of aileron cable failure due to improper installation. The directive ensures that all relevant aircraft are inspected according to the specified technical requirements to maintain operational safety and compliance with international standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Boeing 747 series aeroplanes as outlined in Boeing Service Bulletin 747-27-2367 Revision 1, dated December 17, 1998. This legislation is focused on ensuring the airworthiness of the specified aircraft models by mandating inspections of the aileron cables and their markers. The requirement to inspect these components adheres to the technical stipulations detailed in FAA AD 99-11-15 Amdt 39-11186. The directive was issued following a reported incident of an aileron cable failure due to improper installation, necessitating a one-time visual inspection to ensure that the cables are correctly installed and that the cable markers are properly identified and located. This Airworthiness Directive became effective on September 9, 1999, and compliance is mandated as per the specified requirement document with the revised effective date. The application of this directive is governed by the Commonwealth of Australia and extends to all relevant operators and maintenance entities within the national jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a schedule of airworthiness directives that are essential for ensuring the safety of certain aircraft. One such directive, AD/B747/210, pertains to the Boeing 747 series aeroplanes and focuses on the aileron cable system. This directive (sections 9/99) applies to the model 747 series aircraft as listed in Boeing Service Bulletin 747-27-2367 Revision 1, dated December 17, 1998. The directive requires a thorough inspection of the aileron cables and aileron cable markers in accordance with the technical requirements outlined in FAA AD 99-11-15 Amendment 39-11186. Boeing Service Bulletins 747-27-2367 and its revision are referenced to provide further details on the inspection procedures. Under these regulations, the parties or entities governed by this airworthiness directive must adhere to the specified requirements. This includes conducting a visual inspection of the aileron cables to detect any instances of improper installation or fraying, as well as inspecting the cable markers to ensure they are correctly identified and positioned. Compliance with the directive must be achieved in line with the requirements document, with the revised effective date set as 9 September 1999. It is imperative that the inspection is conducted in a manner that ensures the safety and airworthiness of the Boeing 747 series aircraft. Failure to comply with the provisions of this airworthiness directive can result in significant consequences. The background of the directive indicates that it was issued in response to a report of an aileron cable failure due to improper installation, which underscores the importance of strict adherence to the directive's requirements. While the specific penalties for non-compliance are not detailed in the provided text, it is reasonable to infer that any breach of these safety regulations could lead to serious civil or criminal penalties. The overarching objective is to prevent any incidents that could compromise the safety of the aircraft and its occupants.
