COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 767 Series Aeroplanes
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.
AD/B767/129 APU Standby Power Feeder Cable 13/2000
Applicability: Model 767 series aeroplanes listed in Boeing Alert Service Bulletin (ASB) 767- 24A0126 dated 24 February 2000.
Requirement: Install sleeving on the 90-minute auxiliary power unit (APU) standby power feeder cable at body station 1351 on the left side of the aeroplane, in accordance with ASB 767-24A0126.
Note: FAA AD 2000-21-04 Amdt 39-11936 refers.
Compliance: Within six months after the effective date of this Directive.
This Airworthiness Directive becomes effective on 28 December 2000.
Background: Boeing received a report of damage to the 90-minute APU standby power feeder cable caused by shifting of unrestrained cargo containers during flight. This Directive requires sleeving of the standby power feeder cable. This action is intended to prevent damage to the 90-minute APU standby power feeder cable, which could result in arcing between the standby power feeder cable and the shroud of the APU fuel line, penetration of the fuel line shroud, and a consequent fire in the main deck floor above the aft cargo compartment.

Delegate of the Civil Aviation Safety Authority 13 November 2000
The above AD is notified in the Commonwealth of Australia Gazette on 22 November 2000.
Overview
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, were enacted to ensure the safe operation of aircraft within Australian airspace. The regulations provide a comprehensive framework for maintaining aircraft airworthiness, and they are enforced by the Civil Aviation Safety Authority (CASA). One of the legislative instruments under these regulations is Airworthiness Directive (AD) B767/129, issued on 13 November 2000. This AD addresses a safety issue concerning the Boeing 767 series aeroplanes, particularly the potential damage to the 90-minute auxiliary power unit (APU) standby power feeder cable due to shifting of unrestrained cargo containers during flight. The policy objective of this directive is to prevent potential hazards such as arcing, penetration of the fuel line shroud, and fires by requiring the installation of sleeving on the APU standby power feeder cable. Compliance with this directive must be achieved within six months of its effective date, 28 December 2000.
Scope and Application
The Civil Aviation Regulations 1998, under PART 39 - 105, specifically targets Boeing 767 series aeroplanes, mandating compliance with Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). This legislation applies directly to operators and owners of Model 767 series aeroplanes, ensuring they adhere to safety measures outlined in AD/B767/129, which mandates the installation of sleeving on the 90-minute auxiliary power unit (APU) standby power feeder cable. The directive, which is effective as of 28 December 2000, aims to prevent potential damage to the cable caused by shifting of unrestrained cargo containers, which could lead to serious safety hazards such as fires. This AD is applicable nationally and is enforced across all jurisdictions within Australia, with compliance required within six months of the directive's effective date. The AD is designed to correct an unsafe condition, ensuring the continued airworthiness of the specified aircraft model.
Key Provisions
The Airworthiness Directive (AD) AD/B767/129, issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998, applies specifically to Boeing 767 series aeroplanes listed in Boeing Alert Service Bulletin (ASB) 767-24A0126 dated 24 February 2000. This directive mandates the installation of sleeving on the 90-minute auxiliary power unit (APU) standby power feeder cable at body station 1351 on the left side of the aeroplane, as outlined in ASB 767-24A0126. This action is intended to mitigate the risk of damage to the cable, which could result in serious safety hazards such as arcing, penetration of the fuel line shroud, and potential fire in the main deck floor above the aft cargo compartment.
The obligations imposed by this AD are clear and specific. Operators of Boeing 767 series aeroplanes must ensure that the sleeving is installed on the designated APU standby power feeder cable within six months of the directive's effective date, which was 28 December 2000. This requirement must be carried out in accordance with the instructions provided in the referenced Boeing Alert Service Bulletin. Failure to comply with this directive could result in significant safety risks, compromising the integrity of the aircraft and potentially endangering lives.
In the event of non-compliance with this Airworthiness Directive, there are several potential consequences. Firstly, operators who fail to implement the required modifications risk rendering their aircraft non-airworthy, which could result in grounding of the aeroplane. Additionally, the Civil Aviation Safety Authority (CASA) may take enforcement actions against operators who do not adhere to the directive. Penalties for non-compliance could include fines or other sanctions, as prescribed by the Civil Aviation Regulations. The severity of these penalties is contingent on the extent of the non-compliance and its impact on aviation safety.
