COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 747 Series Aeroplanes
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 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.
AD/B747/219 Lateral Control System Cable Guards 2/2000
Applicability: Model 747 series aircraft, as listed in Boeing Alert Service Bulletin 747-27A2364. Requirement: Action in accordance with the technical requirements of FAA AD 99-24-16 Amdt 39-
11441.
Compliance: Before 4 January 2002, unless already accomplished.
This Airworthiness Directive becomes effective on 24 February 2000.
Background: The FAA received reports of high control wheel forces and restricted control wheel movement in the lateral control system of a Boeing 747 aircraft. Investigation revealed deterioration and splintering of the lateral control system cable guard material into the cable pulley covers in the cabin sidewall area, which resulted in a hard jam in the control system. This Directive requires replacement of the affected cable guards with new, improved cable guards.

The above AD is notified in the Commonwealth of Australia Gazette on 27 January 2000.
Overview
The Civil Aviation Regulations 1998, amended by the Legislative Instrument F2006B03119, address safety concerns in civil aviation, particularly by issuing Airworthiness Directives (AD) that are essential for maintaining the airworthiness of aircraft. The AD concerning Boeing 747 series aeroplanes, specifically AD/B747/219, was enacted to address safety issues related to the lateral control system cable guards. The problem identified was the deterioration and splintering of cable guard material that led to restricted control wheel movement and high control wheel forces, potentially compromising flight safety. The directive was issued by the Civil Aviation Safety Authority (CASA), with the policy objective of ensuring that the necessary actions are taken to rectify the unsafe conditions and maintain the integrity of the aircraft's control systems. The AD requires compliance by a specified date to ensure that the identified safety issues are resolved promptly.
Scope and Application
This Airworthiness Directive applies to Boeing 747 series aircraft, specifically those listed in Boeing Alert Service Bulletin 747-27A2364, and is issued under the Civil Aviation Regulations 1998 by the Civil Aviation Safety Authority (CASA) delegate. The directive mandates actions to rectify an unsafe condition identified in the lateral control system cable guards of these aircraft, requiring compliance with the technical specifications outlined in FAA AD 99-24-16 Amdt 39-11441. The directive must be adhered to before 4 January 2002, unless the required actions have already been completed. The directive became effective on 24 February 2000, and its issuance was gazetted on 27 January 2000. The directive does not extend to other aircraft models or systems beyond the specified lateral control system cable guards of the Boeing 747 series, and no exemptions or exclusions are explicitly stated within the directive itself.
Key Provisions
The Airworthiness Directive (AD) B747/219, issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998), applies specifically to the Boeing 747 series aircraft as listed in Boeing Alert Service Bulletin 747-27A2364. The directive mandates the replacement of the lateral control system cable guards with new, improved guards to address issues of high control wheel forces and restricted movement in the lateral control system, which were traced to deterioration and splintering of the existing cable guard material. The action required must comply with the technical specifications outlined in FAA AD 99-24-16 Amdt 39-11441. Operators must complete this action before 4 January 2002 unless it has already been performed, with the directive becoming effective from 24 February 2000.
The AD imposes specific obligations on the operators of Boeing 747 series aircraft. They must ensure that the lateral control system cable guards are replaced with new, improved guards as specified in the directive. This involves following the technical requirements outlined in FAA AD 99-24-16 Amdt 39-11441. Operators must also ensure that this action is completed by the deadline of 4 January 2002. Failure to comply with this AD can result in the aircraft being deemed non-airworthy, which could lead to grounding of the aircraft and potential operational disruptions. Compliance with the directive is essential for maintaining the safety and airworthiness of the aircraft.
Non-compliance with the Airworthiness Directive B747/219 can have significant consequences. The Civil Aviation Safety Authority (CASA) can take enforcement actions against operators who fail to adhere to the directive. Such actions may include fines, suspension of airworthiness certificates, or even legal proceedings against the operators. The severity of the penalties will depend on the extent of non-compliance and the impact on aviation safety. Under CAR 1998, operators who do not comply with airworthiness directives can face substantial financial penalties and legal ramifications, underscoring the importance of strict adherence to the directive's requirements.
