COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: This Directive requires the modification of the PES installed by STC ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D and the revision of the AFM. This action is required to ensure that, when necessary, the flight crew is able to remove electrical power from the PES and is advised of appropriate procedures for such action. Inability to remove power from the PES 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 July 2001
The above AD is notified in the Commonwealth of Australia Gazette on 15 August 2001.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, was enacted to ensure the safety and airworthiness of aircraft in Australian airspace. This legislation provides a framework for the Civil Aviation Safety Authority (CASA) to issue directives that address specific safety concerns or rectify identified deficiencies in aircraft design, construction, or maintenance. The policy objective of this Act is to maintain the highest possible safety standards in civil aviation by mandating corrective actions to mitigate any identified risks. The Airworthiness Directive (AD) issued under this Act, such as AD/B737/163, targets specific aircraft models and requires modifications to systems like the passenger entertainment system to address potential hazards, ensuring that all aircraft operations comply with stringent safety criteria. This legislative instrument aims to prevent accidents and incidents by enforcing timely and effective safety measures.
Scope and Application
The Airworthiness Directive issued under the Civil Aviation Regulations 1998, specifically within Part 39, pertains to Boeing 737 series aeroplanes. This directive applies to Model 737-700 series airplanes that have been modified by the United States Federal Aviation Administration (FAA) Supplemental Type Certificates (STC) ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D. The directive mandates modifications to the passenger entertainment system (PES) to ensure safety during flight operations, particularly in emergency situations where the removal of electrical power from the PES is necessary. The action required includes installing a power switch and a load-shed circuit breaker, along with associated relays and wiring, in accordance with specified Raytheon Service Bulletins. Furthermore, the Aircraft Flight Manual (AFM) must be revised to inform the flight crew about the new procedures for managing the PES power in emergency scenarios. Compliance with these requirements is necessary within 18 months for the installation of the power switch and associated components, and immediately upon the directive's effective date for the AFM revisions. This directive extends to the national jurisdiction and aims to enhance the safety of the specified aircraft through prescribed modifications and procedural updates.
Key Provisions
The Civil Aviation Regulations 1998 (CAR 1998) under PART 39 - 105, as detailed in the AIRWORTHINESS DIRECTIVES for Boeing 737 Series Aeroplanes, specifically AD/B737/163, mandates certain modifications and updates to the passenger entertainment system (PES) of Model 737-700 series airplanes. The directive applies to aircraft modified by the FAA STC ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D. The directive requires the installation of a power switch and a load-shed circuit breaker, along with associated relays and wiring, as per Raytheon Service Bulletin 737IGW-24-1 dated 11 August 2000. Additionally, it necessitates revisions to the Aircraft Flight Manual (AFM) to include procedures for the flight crew to use the power switch to remove power from the PES during emergencies related to smoke or fire, as outlined in Raytheon Airplane Flight Manual Supplement B737-700 IGW dated 16 October 2000.
The obligations under this Airworthiness Directive are clear: aircraft operators must ensure that the PES modifications and AFM updates are completed within the specified timelines. For Requirement 1, which involves the modification of the PES, operators have 18 months from the effective date of the directive to comply. Requirement 2, which pertains to the revision of the AFM, must be completed immediately upon the directive's effective date. Failure to comply with these requirements will render the PES non-compliant and the aircraft unable to be operated legally until the modifications and updates are fully implemented.
Non-compliance with this Airworthiness Directive can result in significant consequences. The directive outlines that any aeroplane with a PES installed in accordance with the specified FAA STCs that is not modified and updated as required will not be permitted to operate. This non-compliance could potentially lead to regulatory penalties, including fines or suspension of airworthiness certificates. Additionally, operators may face civil liabilities if the non-compliance results in incidents or accidents related to the PES. The severity of these penalties underscores the importance of adhering to the directives to ensure the safety and airworthiness of the aircraft.
