Applicability: Model 767-300 series aeroplanes modified by United States Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) ST01783AT-D.
Requirement: 1. Modify the in- flight entertainment (IFE) system by installing two new relays and a new circuit breaker, in accordance with TIMCO Service Bulletin TSB-767-23- 009, Revision IR dated 22 August 2001.
2. Revise the procedures under "Electrical Smoke or Fire" in the "Emergency Procedures" section of the aircraft flight manual (AFM) to include TIMCO AFM Supplement TIM-AFM-01035 dated 13 March 2002.
Note 1: When the information in the TIMCO AFM supplement has been incorporated into the FAA approved general revisions of the AFM, the general revisions may be incorporated into the AFM, and the AFM supplement may be removed from the AFM.
3. IFE systems may not be installed on any aeroplane in accordance with STC ST01783AT-D unless the IFE system is modified and the AFM is revised according to this Directive.
Note 2: FAA AD 2003-07-15 Amdt 39-12111 refers.
Compliance: For Requirement 1 - Within 18 months after the effective date of this Directive.
For Requirement 2 - Concurrent with the accomplishment of Requirement 1. For Requirement 3 - As of the effective Date of this Directive.
This Airworthiness Directive becomes effective on 10 July 2003.
Boeing 767 Series Aeroplanes
AD/B767/184 (continued)
Background: This Directive requires the modification of the IFE systems installed under STC ST01783AT-D, together with the revision of the AFM. This action is required to ensure that, when necessary, the flight crew is able to remove power from the IFE and is advised of appropriate procedures to perform these actions. 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 aeroplane flight deck or cabin.

Delegate of the Civil Aviation Safety Authority 28 May 2003
The above AD is notified in the Commonwealth of Australia Gazette on 18 June 2003.
Overview
The Airworthiness Directive (AD) issued under the Civil Aviation Act 1988, specifically as part of the AD/B767/184, was enacted to address safety concerns related to the in-flight entertainment (IFE) system in Boeing 767-300 series aeroplanes that have been modified by FAA Supplemental Type Certificate (STC) ST01783AT-D. This legislative instrument aims to rectify an unsafe condition by requiring modifications to the IFE system and updates to the aircraft flight manual (AFM) to ensure the flight crew can effectively manage electrical fires or smoke, thereby maintaining airworthiness standards. The directive, issued by the Civil Aviation Safety Authority (CASA) delegate, Jim Coyne, on 28 May 2003, became effective on 10 July 2003, with specific compliance timelines for the required modifications and AFM revisions. This AD was subsequently notified in the Commonwealth of Australia Gazette on 18 June 2003.
Scope and Application
This Airworthiness Directive (AD) applies specifically to Boeing 767-300 series aeroplanes that have been modified by the United States Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) ST01783AT-D, which pertains to the in-flight entertainment (IFE) system. This AD is issued under the authority of the Civil Aviation Safety Authority (CASA) and is applicable within the jurisdiction of the Commonwealth of Australia. The directive mandates that specific actions be taken to address identified safety concerns with the IFE system, including the installation of new relays and a circuit breaker as per TIMCO Service Bulletin TSB-767-23-009, and the revision of the aircraft flight manual (AFM) to incorporate updated emergency procedures. The requirement to modify the IFE system and update the AFM must be completed within specified timeframes: the IFE system modifications must be completed within 18 months from the effective date of this AD, while the AFM revision must be done concurrently. This AD becomes effective on 10 July 2003, and its provisions must be strictly adhered to ensure the continued airworthiness and safety of the affected aircraft.
Key Provisions
The Airworthiness Directive (AD) AD/B767/184, issued under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998, mandates specific actions to ensure the safety of Boeing 767-300 series aeroplanes modified by FAA STC ST01783AT-D. The directive is applicable to these specific aircraft models (section titled "Applicability"). The primary requirements outlined in the directive include the modification of the in-flight entertainment (IFE) system by installing two new relays and a new circuit breaker, as detailed in TIMCO Service Bulletin TSB-767-23-009, Revision IR dated 22 August 2001 (section titled "Requirement"). Additionally, the directive requires the revision of the aircraft flight manual (AFM) to incorporate TIMCO AFM Supplement TIM-AFM-01035 dated 13 March 2002 under the "Electrical Smoke or Fire" section of the "Emergency Procedures" (section titled "Requirement").
The AD imposes several obligations on the operators and maintenance entities governing these aircraft. Firstly, they must ensure that the IFE system modifications are completed within 18 months from the directive's effective date (section titled "Compliance"). Concurrently, operators must revise the AFM as per the directive’s specifications. Moreover, the AD stipulates that IFE systems cannot be installed unless they are modified and the AFM is revised as per the directive (section titled "Requirement"). These modifications and revisions are necessary to ensure the flight crew can effectively manage IFE-related emergencies.
Failure to comply with the AD may result in significant legal and safety repercussions. The directive explicitly states that IFE systems modified under FAA STC ST01783AT-D must adhere to the modifications and AFM revisions outlined in the AD. Non-compliance could potentially lead to serious safety issues, such as the inability to control smoke or fumes in the aeroplane flight deck or cabin during emergencies. While the AD does not explicitly state penalties for non-compliance, it implies that failure to adhere to these requirements could result in the aircraft being deemed unairworthy, which could lead to grounding and further regulatory action by the Civil Aviation Safety Authority (CASA).
