COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/B747/216 and issues the following AD under subregulation 39.1 (1) of CASR 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/B747/216
Amdt 1
Video Monitor Supports 1/2005
Applicability: Model 747-400 and 400D series aircraft, as listed in Boeing Alert Service Bulletin 747-25A3142 Revision 3, dated 14 August 2003.
Requirement: Action in accordance with the technical requirements of FAA AD 2004-22-15 Amdt 39-13843.
Note: Boeing Alert Service Bulletin 747-25A3142 Revision 3, or later FAA approved revision, refers.
Compliance: As specified in the Requirement document, with a revised effective date of 20 January 2005.
This Amendment becomes effective on 20 January 2005.
Background: The FAA received reports of the video monitor ceiling panels falling into the cabin due to failure of certain latch assemblies during turbulence. This Directive requires installation of strap assemblies on the ceiling panels and rails that support the video monitors.
Amendment 1 is issued in response to a new FAA AD, which for certain aircraft, requires replacement of certain plate assemblies within the ceiling panel strap assemblies with new, improved plate assemblies; and widens the applicability of the directive.

Overview
The Civil Aviation Safety Regulations 1998, amended through the Civil Aviation Safety Regulations 1998, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, were enacted to ensure the safety of aviation operations in Australia by setting standards and issuing directives to correct unsafe conditions. This legislative instrument specifically addresses safety concerns related to the Boeing 747 series aeroplanes by revoking and replacing Airworthiness Directive (AD) AD/B747/216 with a new directive aimed at mitigating the risk of video monitor ceiling panels falling into the cabin during turbulence. The directive requires installation of improved strap assemblies on the ceiling panels and rails supporting the video monitors. The policy objective is to enhance aviation safety by ensuring aircraft meet stringent safety standards. This directive was issued by the Civil Aviation Safety Authority (CASA), a delegate of the Australian government, and became effective on 20 January 2005, as notified in the Commonwealth of Australia Gazette on 22 December 2004.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, which concerns Airworthiness Directives, applies to the aviation industry in Australia, targeting the safety of civil aircraft. This regulatory instrument, issued under the authority of the Civil Aviation Safety Authority (CASA), mandates certain actions to ensure compliance with safety standards for specified aircraft. The regulation directly applies to the Boeing 747-400 and 400D series aircraft, as detailed in Boeing Alert Service Bulletin 747-25A3142 Revision 3, dated 14 August 2003. The requirement stems from a safety concern identified by the Federal Aviation Administration (FAA) regarding the potential failure of video monitor ceiling panel latch assemblies, leading to these panels falling into the cabin during turbulence. The directive mandates adherence to the technical requirements outlined in FAA AD 2004-22-15 Amdt 39-13843, which includes the installation of strap assemblies to secure the video monitors. This directive became effective on 20 January 2005 and amends the previous AD/B747/216 to include additional measures and expand the scope of the directive.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, mandates the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (AD) to ensure the safety of aircraft and aeronautical products. Section 39.1 (1) allows a CASA delegate to revoke existing ADs and issue new ones as necessary. In this instance, AD/B747/216 has been revoked and replaced by a new AD, effective 20 January 2005, addressing safety concerns related to the video monitor ceiling panels on Boeing 747-400 and 400D series aircraft. The AD requires compliance with the technical specifications outlined in FAA AD 2004-22-15 Amdt 39-13843, which includes the installation of strap assemblies on the ceiling panels and rails supporting the video monitors to prevent them from falling into the cabin during turbulence.
The AD imposes obligations on the operators of the affected Boeing 747-400 and 400D series aircraft to ensure that they comply with the requirements specified in the new directive. This includes taking action to install the necessary strap assemblies as per the instructions outlined in FAA AD 2004-22-15 Amdt 39-13843. Compliance must be achieved by the specified effective date, 20 January 2005, and operators must adhere to any further instructions or revisions issued by CASA or the FAA.
Failure to comply with the AD may result in civil or criminal consequences. The AD specifies that the installation of the strap assemblies must be carried out to ensure the safety of the aircraft and its occupants. If an operator fails to comply with the AD, they may face regulatory action from CASA, which could include fines or other penalties. The exact penalties are not specified in the AD but are governed by the broader provisions of the Civil Aviation Act 1988 and associated regulations. Non-compliance could also lead to the grounding of the affected aircraft, potentially resulting in significant operational disruptions and financial losses for the operator.
