For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) No AD/B767/109 and issues the following 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 767 Series Aeroplanes
AD/B767/109
Amdt 1
Engine Indicating and Crew Alerting System 2/2002
Applicability: Model 767 series aeroplanes identified in Boeing Service Bulletins (SB) 767-31-0098 dated 27 August 1998, 767-31-0091 Revision 1 dated 4 February 1999 or 767-31-
0099 Revision 3 dated 8 February 2001.
Requirement: 1. For aeroplanes with General Electric engines - Install an upgraded engine indicating and crew alerting system (EICAS) computer in accordance with either SB 767-31-0098 or 767-31-0091 Revision 1, as applicable.
2. For aeroplanes with Rolls Royce engines - Unless previously accomplished, install an upgraded EICAS computer in accordance with SB 767-31-0099 Revision 3 dated 8 February 2001.
Note: FAA AD 96-07-09 Amdt 39-9558 refers.
Compliance: For Requirement 1 - Remains unchanged, No later than 1 June 2001.
For Requirement 2 - No later than 21 March 2002.
This Amendment becomes effective on 21 February 2002.
Background: The Federal Aviation Administration issued an airworthiness directive following a finding that EICAS computers currently installed on certain Boeing 767 aeroplanes do not provide an appropriate indication to the flight crew of an impending fuel filter bypass condition. Replacement of the EICAS computer ensures that the flight crew is aware of conditions involving a severely contaminated fuel system and the associated increased potential for engine power loss.
The original issue of this Directive addressed 767 aeroplanes with engines manufactured by General Electric. This amendment introduces similar requirements for 767 aeroplanes with Rolls Royce RB211 engines.

Overview
The Civil Aviation Safety Authority (CASA) issued an Airworthiness Directive (AD) for Boeing 767 series aeroplanes in 2002 to address a safety concern related to the Engine Indicating and Crew Alerting System (EICAS). The directive, AD/B767/109 Amendment 1, was enacted to correct an unsafe condition where the EICAS computers did not provide appropriate indications to the flight crew of an impending fuel filter bypass condition. This could result in the flight crew being unaware of severely contaminated fuel systems and the associated risk of engine power loss. The AD requires specific actions to be taken for aeroplanes with either General Electric or Rolls Royce engines, including the installation of an upgraded EICAS computer, in line with specified Boeing Service Bulletins. The directive aims to ensure that flight crews are properly alerted to potential issues, thereby enhancing the safety of air travel. This legislative instrument was issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998.
Scope and Application
The Airworthiness Directive (AD) No AD/B767/109 Amdt 1, issued by the Civil Aviation Safety Authority (CASA), applies specifically to Boeing 767 series aeroplanes identified in Boeing Service Bulletins (SB) 767-31-0098 dated 27 August 1998, 767-31-0091 Revision 1 dated 4 February 1999, or 767-31-0099 Revision 3 dated 8 February 2001. This AD mandates that operators of these aeroplanes must install an upgraded engine indicating and crew alerting system (EICAS) computer to address the unsafe condition identified, which pertains to the inadequate indication of an impending fuel filter bypass condition. The requirement varies based on the engine type, with General Electric engines needing an upgrade by 1 June 2001, and Rolls Royce engines requiring the upgrade by 21 March 2002. The AD extends across the Commonwealth of Australia and is effective as of 21 February 2002, following its notification in the Commonwealth of Australia Gazette on 30 January 2002. This legislative instrument does not explicitly mention exclusions, exemptions, or thresholds, but compliance is mandatory for the specified aircraft and conditions.
Key Provisions
This legislative instrument, the Airworthiness Directive (AD) No AD/B767/109 Amdt 1, applies to Boeing 767 series aeroplanes as identified in specific Boeing Service Bulletins (subsection 1(1)). The AD mandates specific actions to address an unsafe condition related to the Engine Indicating and Crew Alerting System (EICAS) of these aeroplanes. For aeroplanes with General Electric engines, it requires the installation of an upgraded EICAS computer according to Boeing Service Bulletins 767-31-0098 or 767-31-0091 Revision 1 (subsection 1(2)(a)). For aeroplanes with Rolls Royce engines, it requires the installation of an upgraded EICAS computer according to Boeing Service Bulletin 767-31-0099 Revision 3, unless this has already been completed (subsection 1(2)(b)). The directive specifies compliance timelines, with aeroplanes with General Electric engines needing to comply by 1 June 2001 and aeroplanes with Rolls Royce engines needing to comply by 21 March 2002 (subsection 1(3)). This amendment becomes effective on 21 February 2002.
The AD imposes obligations on the operators of Boeing 767 series aeroplanes to ensure that the specified EICAS upgrades are carried out according to the detailed instructions in the referenced Boeing Service Bulletins. Operators must verify the applicability of the AD to their specific aircraft by checking the relevant Service Bulletins and take the necessary action within the specified timeframes to ensure compliance. Failure to comply with the AD may result in the aeroplane being considered unairworthy, which could lead to the aeroplane being grounded and unable to operate until the required upgrades are completed.
Failure to comply with the requirements of this Airworthiness Directive can have significant consequences. The primary consequence is that the affected aeroplanes may be deemed unairworthy, which means they cannot legally operate until the specified upgrades are completed. This could result in substantial financial losses for operators due to grounded aircraft and the associated costs of delay. Furthermore, operators who fail to comply with the AD could face enforcement actions by the Civil Aviation Safety Authority (CASA), which could include fines or other penalties as prescribed by relevant aviation regulations. While specific penalties are not detailed in the AD, non-compliance with CASA directives can lead to significant regulatory and financial repercussions for the operators.
