COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Boeing 747 Series Aeroplanes
AD/B747/263 Rudder Pedal Pushrod Fastener 1/2002
Applicability: Boeing 747 series aircraft; as listed in Boeing Alert Service Bulletin 747-27A2373 dated 24 June 1999.
Requirement: Action in accordance with the technical requirements of FAA AD 2001-22-13 Amdt 39-12492.
Compliance: As specified in the Requirement document with a revised effective date of 24 January 2002.
This Airworthiness Directive becomes effective on 24 January 2002.
Background: The FAA requires replacement of the rudder pedal fasteners for both the captain’s and the first officer’s pedal assemblies with new, improved fasteners. This action is required to prevent loss of rudder control due to improperly torqued fasteners that connect the pushrod to the rudder pedal assembly, which could result in loss of controllability of the aircraft.

Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive legal framework for the regulation of civil aviation within the country. This includes the establishment of safety standards and procedures to ensure the safety of aircraft and passengers. One specific legislative instrument under this Act is the Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA). The directive aims to address safety issues by requiring specific actions to be taken on certain aircraft models to rectify identified unsafe conditions. For example, Airworthiness Directive AD/B747/263 was introduced to address a potential safety issue with the rudder pedal pushrod fastener on Boeing 747 series aircraft, as highlighted in Boeing Alert Service Bulletin 747-27A2373 dated 24 June 1999. This directive mandates the replacement of fasteners to prevent loss of rudder control, thereby ensuring the continued airworthiness and safety of the aircraft. The policy objective of such directives is to maintain high safety standards and prevent accidents by addressing identified hazards in a timely and effective manner.
Scope and Application
This Airworthiness Directive applies to Boeing 747 series aeroplanes as specified in Boeing Alert Service Bulletin 747-27A2373 dated 24 June 1999. The directive mandates specific action to address an identified unsafe condition concerning the rudder pedal pushrod fasteners, necessitating their replacement with improved fasteners in accordance with the technical requirements of FAA AD 2001-22-13 Amdt 39-12492. The purpose of this directive is to mitigate the risk of loss of rudder control due to improperly torqued fasteners, which could lead to a loss of controllability of the aircraft. Compliance with this directive must be achieved by the effective date of 24 January 2002, as specified in the requirement document. The Civil Aviation Safety Authority delegate, David Alan Villiers, issued this directive under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, and it was published in the Commonwealth of Australia Gazette on 9 January 2002.
Key Provisions
The main operative sections of this Airworthiness Directive (AD) pertain to the applicability, requirement, and compliance details of the directive itself. The applicability section (a) specifies the Boeing 747 series aircraft that are subject to the AD, as detailed in the Boeing Alert Service Bulletin 747-27A2373 dated 24 June 1999. The requirement section (b) mandates that the action specified in FAA AD 2001-22-13 Amdt 39-12492 must be taken in accordance with the technical requirements outlined. This action involves replacing the rudder pedal fasteners to prevent potential loss of rudder control. The compliance section (c) sets a revised effective date of 24 January 2002, indicating when the AD must be implemented.
The AD imposes obligations on the operators and maintenance personnel of the Boeing 747 series aircraft. They are required to replace the rudder pedal fasteners in both the captain’s and the first officer’s pedal assemblies with new, improved fasteners as specified. This ensures the safety of the aircraft by preventing issues that could arise from improperly torqued fasteners, which might lead to a loss of controllability. Compliance with the directive is mandatory, and the AD must be adhered to in accordance with the given timeframe and instructions.
Breaches of the AD could result in serious consequences, as it is designed to address a critical safety issue. Failure to comply with the AD could lead to potential safety risks, including loss of rudder control. While the specific civil or criminal penalties are not outlined in the text, non-compliance with ADs is generally taken very seriously by regulatory bodies. Penalties could include fines, grounding of the aircraft, or even more severe consequences depending on the severity of the breach and its impact on safety. The AD is a regulatory tool designed to prevent unsafe conditions and ensure the highest standards of aircraft safety are maintained.
