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/B767/152 In-Flight Entertainment System FAA STC SA4998NM
10/2001
Applicability: Model 767-200 series aeroplanes modified by United States Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) SA4998NM.
Requirement: 1. Modify the in-flight entertainment (IFE) system in accordance with Flight Structures Service Bulletin (SB) 89FS134-23-01, Revision 2, dated 21 September 2000 to change the source of electrical power for the IFE system from the main electrical bus to a utility electrical bus.
2. IFE may not be installed on any aeroplane in accordance with STC SA4998NM unless it is modified in accordance with Flight Structures SB 89FS134-23-01, Revision 2.
Note: FAA AD 2001-16-21 Amdt 39-12390 refers.
Compliance: For Requirement 1 - Within 18 months after the effective date of this Directive.
For Requirement 2 - As of the effective date of this Directive.
This Airworthiness Directive becomes effective on 4 October 2001.
Background: This Directive requires modification of the electrical circuits that supply power to IFE systems installed by STC SA4998NM. This action is required to ensure that, when necessary, the flight crew is able to remove power from the IFE system. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin.

Delegate of the Civil Aviation Safety Authority 23 August 2001
The above AD is notified in the Commonwealth of Australia Gazette on 12 September 2001.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, provide a comprehensive framework for ensuring the safety and regulation of civil aviation within Australia. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 addresses the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to address identified safety issues with aircraft or aeronautical products. The AD/B767/152 is an example of such a directive, issued to address an identified unsafe condition with the in-flight entertainment system in Boeing 767-200 series aeroplanes modified by FAA STC SA4998NM. This AD was introduced to ensure that the flight crew is able to remove power from the IFE system in non-normal or emergency situations, thus mitigating the risk of smoke or fumes in the flight deck or cabin. The policy objective is to maintain the highest possible safety standards in civil aviation by mandating specific modifications to aircraft systems when necessary.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate Airworthiness Directives (ADs) that are necessary to ensure the safety of civil aircraft operating within Australia's jurisdiction. This particular Airworthiness Directive (AD/B767/152) applies to Boeing 767-200 series aeroplanes that have been modified with the in-flight entertainment (IFE) system as per United States Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) SA4998NM. The directive is issued by the Civil Aviation Safety Authority (CASA) and requires specific modifications to the IFE system to ensure safety, particularly in relation to the electrical power source of the system. The modifications must be carried out within 18 months from the effective date of the directive, which was set to be 4 October 2001, and are aimed at ensuring the flight crew can safely remove power from the IFE system during non-normal or emergency situations, thus preventing potential fire hazards from smoke or fumes. This directive is applicable nationally within the Commonwealth of Australia and is intended to align with international safety standards, particularly those set by the FAA.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39, Section 105, outlines the requirements and procedures for issuing Airworthiness Directives (ADs) through the Civil Aviation Safety Authority (CASA). Specifically, Section 39.1(1) of the Regulations allows the CASA delegate to issue ADs when necessary to correct unsafe conditions in aircraft or aeronautical products. The AD in question, AD/B767/152, pertains to Boeing 767 Series Aeroplanes and specifically targets modifications to the in-flight entertainment (IFE) system. This directive is applicable to Model 767-200 series aeroplanes that have been modified under the United States Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) SA4998NM.
The AD mandates that certain modifications be made to the IFE system to change its power source from the main electrical bus to a utility electrical bus. This modification is essential to ensure that the flight crew can remove power from the IFE system during non-normal or emergency situations. Failure to make these modifications could result in an inability to control smoke or fumes within the flight deck or cabin, posing a significant safety risk. The directive specifies that the modification must be completed in accordance with Flight Structures Service Bulletin (SB) 89FS134-23-01, Revision 2, dated 21 September 2000.
Entities governed by this AD, such as aircraft operators and maintenance providers, must adhere to the compliance timeline and technical specifications outlined in the directive. Specifically, Requirement 1 mandates that the IFE system modifications be completed within 18 months from the effective date of the AD, while Requirement 2 states that IFE systems must not be installed unless they are modified in compliance with the AD, effective immediately upon the AD's effective date. This requirement ensures that all modifications are implemented promptly and that any aeroplanes modified under STC SA4998NM are brought into compliance with the safety standards set forth by CASA.
Failure to comply with the AD may result in various consequences, including potential safety risks and legal repercussions. The AD does not explicitly state penalties for non-compliance, but non-compliance with CASA directives generally falls under the broader regulatory framework of the Civil Aviation Act 1988. This could lead to enforcement actions, including fines, suspension of airworthiness certificates, or other administrative penalties. Given the potential risks to flight safety, strict adherence to the AD is imperative for all affected parties.
