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 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/B767/139 Potable Water Fill Line 7/2001
Applicability: All Boeing 767-200 and -300 series aircraft.
Requirement: 1. Replace the existing potable water fill line tube with a flexible hose in accordance with Boeing Alert Service Bulletin 767-38A0057.
2. No person shall install a potable water fill tube, part number 417T2021-179, on an Australian registered Boeing 767-200 or -300 series aircraft.
Note: FAA AD 2001-08-22 refers.
Compliance: 1. No later than 1 June 2002.
2. As of the effective date of this Airworthiness Directive.
This Airworthiness Directive becomes effective on 12 July 2001.
Background: This Airworthiness Directive is prompted by advice that fracture of the clamshell coupling can result in a large amount of water entering the aft cargo compartment. If this occurs, the aircraft’s centre of gravity could shift aft to the extent that controllability of the aircraft is adversely affected.

The above AD is notified in the Commonwealth of Australia Gazette on 13 June 2001.
Overview
The Civil Aviation Regulations 1998 (CAR 1998), enacted by the Australian Parliament, regulate various aspects of civil aviation to ensure the safety of air travel within the country. The CAR 1998 addresses gaps in aviation safety and operational standards, aiming to prevent incidents and accidents. One of the specific regulations under CAR 1998, the Airworthiness Directive (AD) AD/B767/139 issued on 7 July 2001, targets the Boeing 767 Series Aeroplanes. This directive was issued by the Civil Aviation Safety Authority (CASA) to address an unsafe condition identified in the potable water fill line, which could potentially cause a significant water leak into the aft cargo compartment, adversely affecting the aircraft's centre of gravity and controllability. The policy objective of this AD is to mandate the replacement of the existing fill line tube with a flexible hose to mitigate the risk of such an unsafe condition.
Scope and Application
The Airworthiness Directive (AD) AD/B767/139 applies specifically to all Boeing 767-200 and -300 series aircraft registered in Australia. The AD mandates that the existing potable water fill line tube be replaced with a flexible hose to mitigate the risk of fracture, which could lead to water ingress in the aft cargo compartment, thereby potentially affecting the aircraft's centre of gravity and controllability. This directive is issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 by a delegate of the Civil Aviation Safety Authority (CASA). The directive references FAA AD 2001-08-22 and requires compliance by 1 June 2002, effective from 12 July 2001. Furthermore, it prohibits the installation of a specific part number, 417T2021-179, on Australian registered Boeing 767-200 or -300 series aircraft. The AD was published in the Commonwealth of Australia Gazette on 13 June 2001, ensuring its legal enforcement and broad dissemination to relevant stakeholders.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, contains an Airworthiness Directive (AD) AD/B767/139 dated 7/2001. This AD pertains to all Boeing 767-200 and -300 series aircraft (s.1). The directive mandates two key actions: firstly, the replacement of the existing potable water fill line tube with a flexible hose in accordance with Boeing Alert Service Bulletin 767-38A0057 (s.1(a)); and secondly, prohibits the installation of a specific potable water fill tube part number 417T2021-179 on Australian registered Boeing 767-200 or -300 series aircraft (s.1(b)). The compliance period for these requirements is set to no later than 1 June 2002, and the directive becomes effective as of its date, 12 July 2001 (s.2).
This AD imposes specific obligations on aircraft operators and maintenance personnel to ensure the safety of Boeing 767-200 and -300 series aircraft. Operators must ensure that the potable water fill line tube is replaced with a flexible hose as specified in the directive, adhering to the instructions provided in Boeing Alert Service Bulletin 767-38A0057. Additionally, they are prohibited from installing the specified part number 417T2021-179. These actions are crucial to prevent potential safety issues such as water ingress in the aft cargo compartment, which could compromise the aircraft's controllability by shifting its centre of gravity aft (s.1, s.Background).
Failure to comply with this Airworthiness Directive can lead to severe consequences. Under the Civil Aviation Regulations 1998, non-compliance may result in both civil and criminal penalties. The specific penalties for breaches are not detailed in the directive but can include fines and imprisonment, as stipulated under the broader regulatory framework governing civil aviation safety in Australia. The seriousness of the directive reflects the potential risk to flight safety, underscoring the importance of strict adherence to the mandated actions and timeframes (s.2).
