COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 125 Series Aeroplanes
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/HS 125/154 and issues the following 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/HS 125/154
Amdt 1
Engine Pylon Firewall 7/2000
Applicability: Model BAe 125-800A and BAe 125-800B, Model Hawker 800, and Model Hawker 800XP series aircraft; as listed in Raytheon Service Bulletin SB.54-1-3815B, Revision 1, dated May 1998.
Requirement: Fill all unused tooling holes in the left and right engine pylon firewalls with firewall sealant, in accordance with Raytheon Service Bulletin SB.54-1-3815B, Revision 1.
Note: FAA AD 2000-08-07 Amdt 39-11693 refers.
Compliance: Before 13 January 2001, unless already accomplished. This Amendment becomes effective on 13 July 2000.
Background: Reports were received of aircraft with two unused (open) tooling holes on the left hand and right hand engine pylon firewalls which may permit an engine fire moving to the fuselage, and to the lines that carry flammable fluid that are located inboard of the firewall.
Amendment 1 is issued in response to a new FAA AD which requires further action due to reports of additional unused tooling holes, found at locations other than those previously addressed.
The original issue of this Airworthiness Directive became effective on 15 August 1996.

The above AD is notified in the Commonwealth of Australia Gazette on 14 June 2000.
Overview
The Civil Aviation Regulations 1998 (CAR 1998), administered by the Civil Aviation Safety Authority (CASA), are designed to ensure the safety of civil aviation in Australia. One such legislative instrument, F2006B10435, issued in 2000, addresses a specific safety concern related to the British Aerospace BAe 125 Series aeroplanes. This Airworthiness Directive (AD) was introduced to mitigate risks associated with unused tooling holes in the engine pylon firewalls of certain BAe 125 models, which could potentially lead to engine fires spreading to the fuselage and critical fluid lines. The AD mandates that all unused tooling holes in the firewalls must be sealed using specific sealant, as outlined in Raytheon Service Bulletin SB.54-1-3815B, Revision 1. This directive responds to reports and an earlier Federal Aviation Administration (FAA) AD, aiming to enhance aircraft safety by preventing fire hazards. The AD was issued under the authority of the CASA delegate and became effective on 13 July 2000, requiring compliance by 13 January 2001, unless the action had already been completed.
Scope and Application
The Airworthiness Directive (AD) AD/HS 125/154 applies specifically to British Aerospace BAe 125 Series Aeroplanes, namely the BAe 125-800A and BAe 125-800B, as well as the Hawker 800 and Hawker 800XP series aircraft. This directive is issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 and mandates that all unused tooling holes in the left and right engine pylon firewalls of the specified aircraft models be filled with firewall sealant, in accordance with Raytheon Service Bulletin SB.54-1-3815B, Revision 1. The directive is aimed at rectifying the unsafe condition identified in which unused holes could potentially lead to engine fires spreading to the fuselage and flammable fluid lines. Compliance with this directive must be achieved before 13 January 2001 unless the required action has already been taken. The AD is part of a broader safety initiative in response to reports from both CASA and the Federal Aviation Administration (FAA), and it extends across the Commonwealth of Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, includes an Airworthiness Directive (AD) aimed at addressing safety concerns with British Aerospace BAe 125 Series aeroplanes. This AD, AD/HS 125/154 Amendment 1, pertains to the BAe 125-800A, BAe 125-800B, Hawker 800, and Hawker 800XP series aircraft. The directive mandates that all unused tooling holes in the left and right engine pylon firewalls must be filled with firewall sealant as per Raytheon Service Bulletin SB.54-1-3815B, Revision 1, dated May 1998, to prevent potential engine fires from spreading to the fuselage and flammable fluid lines. The AD requires this action to be taken before 13 January 2001, unless it has already been completed, and it became effective on 13 July 2000.
The Civil Aviation Regulations impose several obligations on the operators and owners of the affected aircraft. Firstly, they must ensure that the specified aircraft models comply with the AD by filling all unused tooling holes in the engine pylon firewalls with the appropriate firewall sealant. This must be done in accordance with the instructions provided in Raytheon Service Bulletin SB.54-1-3815B, Revision 1. Compliance with the directive is mandatory and must be achieved by the specified deadline, with the AD having been effective from 13 July 2000. Operators and owners must ensure that their aircraft meet these requirements to maintain airworthiness.
Failure to comply with the provisions of the AD may result in significant legal consequences. The AD is a regulatory requirement under the Civil Aviation Regulations 1998, and non-compliance could be considered a breach of these regulations. The specific civil or criminal penalties for non-compliance are not detailed in the directive itself, but generally, such breaches can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, penalties, or even the grounding of non-compliant aircraft until the required actions are taken. The exact penalties would be determined in accordance with the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998.
