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 767 Series Aeroplanes
AD/B767/171 Flight Compartment Air Distribution Duct 7/2002
Applicability: All model 767 series aircraft having the line numbers listed in the requirement document.
Requirement: 1. Inspect, rework or replace if necessary the water line heater tape and the duct assemblies of the flight compartment air distribution system in accordance with paragraph (a) of the technical requirements of FAA AD 2001-26-09 Amdt 39- 12573.
2. Replace the duct assemblies or replace the existing BMS 8-39 foam insulation on the ducts of the air distribution system for the flight compartment in accordance with paragraph (b) of the technical requirements of FAA AD 2001-26-09 Amdt 39-12573.
Note: Boeing Alert Service Bulletin 767-21A0154 Revision 1 dated 9 August 2001 refers.

Delegate of the Civil Aviation Safety Authority 27 May 2002
The above AD is notified in the Commonwealth of Australia Gazette on 19 June 2002.
Overview
The Civil Aviation Regulations 1998, as amended, serve as the primary regulatory framework for civil aviation safety in Australia, overseen by the Civil Aviation Safety Authority (CASA). Part 39 of these regulations, specifically addressing Airworthiness Directives, is instrumental in ensuring that aircraft and aeronautical products meet the necessary safety standards. The Airworthiness Directive (AD) for Boeing 767 Series Aeroplanes, issued in July 2002, was introduced to address safety concerns regarding the potential ignition of foam insulation on the air distribution ducts, which could lead to fires. This AD, issued under the authority of CASA, mandates specific actions to be taken on the affected aircraft, such as inspecting, reworking, or replacing the duct assemblies and insulation as per the Federal Aviation Administration's (FAA) directives. The objective is to mitigate the risk of fire, ensuring the continued airworthiness and safety of Boeing 767 aircraft in Australian airspace.
Scope and Application
The Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) applies specifically to all model 767 series aircraft within the specified line numbers, as outlined in the requirement section. This regulatory measure is aimed at ensuring the safety of the aircraft by addressing potential fire hazards associated with the foam insulation on the flight compartment air distribution ducts. The directive mandates that specified inspections, reworks, and replacements of the water line heater tape, duct assemblies, and foam insulation be conducted in accordance with detailed technical requirements. These actions must be completed by specific deadlines, with the initial compliance required before 11 January 2004 and the subsequent compliance due before 11 July 2008. The directive extends its jurisdiction over all such aircraft operating within the Australian jurisdiction, ensuring that these safety measures are uniformly enforced across the Commonwealth. The AD is derived from the Federal Aviation Administration's (FAA) Airworthiness Directive 2001-26-09, which has been adapted to align with Australian regulatory standards.
Key Provisions
The Civil Aviation Regulations 1998 (CAR 1998) under PART 39 - 105, specifically through the Airworthiness Directive (AD) AD/B767/171, mandates specific actions for the Boeing 767 series aircraft to ensure safety in the flight compartment air distribution system. The AD requires inspection, rework, or replacement of the water line heater tape and duct assemblies of the air distribution system, as detailed in FAA AD 2001-26-09 Amendment 39-12573 (paragraph a). Additionally, it requires the replacement of duct assemblies or the existing BMS 8-39 foam insulation on the ducts in the flight compartment, following FAA AD 2001-26-09 Amendment 39-12573 (paragraph b). Boeing Alert Service Bulletin 767-21A0154 Revision 1 dated 9 August 2001 also references this requirement.
The AD imposes specific obligations on the operators of Boeing 767 series aircraft. These operators must ensure that the inspections, reworks, or replacements are conducted on the water line heater tape and duct assemblies of the flight compartment air distribution system by the specified dates. The directive also mandates the replacement of duct assemblies or foam insulation on the ducts within the stipulated timeframes. Operators must adhere to the instructions outlined in FAA AD 2001-26-09 Amendment 39-12573 and Boeing Alert Service Bulletin 767-21A0154 Revision 1 to comply with the AD.
Failure to comply with the AD's requirements can result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce these requirements, and non-compliance could lead to the grounding of the aircraft, fines, or other civil penalties. The AD is designed to prevent potential ignition of foam insulation, which could result in a fire in the aircraft. The urgency and specific compliance dates underscore the importance of adhering to these safety measures to prevent hazardous conditions.
