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 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/B747/240 Air Conditioning Duct Insulation 4/2001
Applicability: Model 747 series aircraft having the line numbers listed in the requirement document.
Requirement: Rework duct assemblies or replace existing duct assemblies with new or reworked items in accordance with the technical requirements of FAA AD 2000-26-05 Amdt 39-12055.
Compliance: Before 19 April 2007.
This Airworthiness Directive becomes effective on 19 April 2001.
Background: An FAA AD has been raised to prevent potential ignition of fibreglass insulation material installed on the outside of the Environmental control system (ECS) ducts, which could propagate a small fire and lead to a larger fire.

Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to provide a comprehensive regulatory framework governing civil aviation operations in Australia. One of the specific measures introduced under these regulations is the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). For instance, Airworthiness Directive AD/B747/240, issued on 5 March 2001 and effective from 19 April 2001, addresses a safety concern regarding Boeing 747 series aircraft. The directive mandates the rework or replacement of air conditioning duct insulation to prevent potential fire hazards arising from fibreglass insulation material. This directive is a response to an earlier Federal Aviation Administration (FAA) Airworthiness Directive aimed at mitigating the risk of fire propagation, thereby ensuring the continued safety of civil aviation operations.
Scope and Application
The Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 pertains specifically to Boeing 747 series aircraft, affecting those with the particular line numbers listed in the requirement document. This directive applies to the aeronautical product in question to address a recognised unsafe condition, requiring either the reworking of duct assemblies or their replacement with new or reworked items in accordance with the technical requirements specified in FAA AD 2000-26-05 Amdt 39-12055. The directive mandates compliance by a specified date, in this case, before 19 April 2007. This Airworthiness Directive, which became effective on 19 April 2001, aims to prevent potential ignition of fibreglass insulation material installed on the outside of the Environmental Control System (ECS) ducts, which could lead to a larger fire if left unchecked. The directive applies nationally within the Commonwealth of Australia and is notified in the Commonwealth of Australia Gazette to ensure awareness and compliance among relevant stakeholders.
Key Provisions
The Airworthiness Directive (AD) issued under section 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) pertains specifically to the Boeing 747 series aeroplanes and mandates the rework or replacement of air conditioning duct assemblies to address potential safety risks. According to the directive, the action must be taken on aircraft with the specified line numbers, and it must be carried out in accordance with the technical requirements outlined in FAA AD 2000-26-05 Amdt 39-12055. The directive specifies that the compliance deadline is before 19 April 2007, and it became effective on 19 April 2001. This directive aims to prevent potential ignitions of fibreglass insulation material, which could lead to fires.
Under this AD, the obligations imposed on the relevant parties include ensuring that the specified Boeing 747 series aircraft undergo the necessary rework or replacement of air conditioning duct assemblies. The requirement to adhere to the technical specifications detailed in FAA AD 2000-26-05 Amdt 39-12055 is critical, and these specifications must be meticulously followed to comply with the directive. Compliance with the directive's timeline is also mandatory, as failure to meet the deadline could result in the aircraft being deemed non-airworthy.
In the event of non-compliance with this AD, there could be significant legal and safety consequences. While the specific penalties or consequences are not detailed in the text, non-compliance with airworthiness directives can generally lead to enforcement actions by the Civil Aviation Safety Authority (CASA). This could include fines, grounding of the aircraft, and potential criminal charges if the non-compliance results in safety incidents. The exact penalties would depend on the severity and impact of the non-compliance as determined by CASA.
