AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/AMD 50/22 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.
AMD Falcon 50 and 900 Series Aeroplanes
AD/AMD 50/22
Amdt 1
Baggage Compartment Fire Extinguisher 8/2002
Applicability: All Mystere Falcon 900 aircraft serial number 1 through 59 not incorporating Mod M3368 and Mod M874, Falcon 900 aircraft serial number 60 through 187 not incorporating Mod M3368, and Falcon 900EX aircraft not incorporating Mod M3368 or Service Bulletin F900EX-142.
Requirement: Incorporate a support assembly for the baggage compartment fire extinguisher discharge nozzle in accordance with:
Dassault Aviation Service Bulletin F900-279 Revision 1 (Mod M3368 and Mod M874) for Mystere Falcon 900 aircraft.
Dassault Aviation Service Bulletin F900EX-142 for Mystere Falcon 900EX aircraft.
Note: DGAC AD 2002-261(B) and DGAC AD 2001-192-034(B) Revision 1 refers.
Compliance: Within 330 flight hours after the effective date of this Directive, but, no later than 8 February 2003.
This amendment becomes effective on 8 August 2002.
Background: The manufacturer reports that the baggage compartment fire extinguisher nozzle can be damaged, resulting in insufficient distribution of the fire-extinguishing agent in the event of a compartment fire.
This amendment adds a requirement by the manufacturer to incorporate a modification not previously incorporated on certain serial number aircraft. Additionally both models of aircraft now have unique Service Bulletins to reflect the requirements.

Overview
The Civil Aviation Safety Authority (CASA) has enacted Airworthiness Directive (AD) AD/AMD 50/22 Amendment 1 to address a safety issue with the Mystere Falcon 900 and Falcon 900EX aircraft models. This AD was issued to rectify the unsafe condition related to the insufficient distribution of fire-extinguishing agent from the baggage compartment fire extinguisher nozzle, which can lead to ineffective fire suppression in the event of a compartment fire. The AD mandates the incorporation of a support assembly for the fire extinguisher discharge nozzle as outlined in specific Dassault Aviation Service Bulletins. This requirement applies to certain serial numbers of the Mystere Falcon 900 aircraft and Falcon 900EX aircraft that do not currently have the necessary modifications. Compliance with this AD must occur within 330 flight hours from the effective date of the directive or by 8 February 2003, whichever is later. This amendment was made effective on 8 August 2002, and the directive was subsequently notified in the Commonwealth of Australia Gazette on 17 July 2002.
Scope and Application
The Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 applies specifically to certain serial numbers of Mystere Falcon 900 and Falcon 900EX aircraft. The directive mandates the incorporation of a support assembly for the baggage compartment fire extinguisher discharge nozzle to address safety concerns identified by the manufacturer. These aircraft must comply with the new requirements within 330 flight hours from the effective date of the directive, with an absolute deadline of 8 February 2003. The directive applies to Mystere Falcon 900 aircraft serial numbers 1 through 59 and 60 through 187 that do not include modifications M3368 and M874, as well as Falcon 900EX aircraft that lack modification M3368 or Service Bulletin F900EX-142. The regulation is designed to mitigate the risk of insufficient fire-extinguishing agent distribution in the event of a baggage compartment fire, ensuring the continued airworthiness and safety of the specified aircraft models. The directive is issued under the authority of the CASA delegate, and its requirements are enforceable within the Commonwealth of Australia.
Key Provisions
The Airworthiness Directive (AD) under consideration is primarily concerned with the safety of Mystere Falcon 900 aircraft, specifically addressing a defect related to the baggage compartment fire extinguisher system. Section (a) of the applicability identifies the specific aircraft models affected: all Mystere Falcon 900 aircraft serial numbers 1 through 59 that do not incorporate modifications M3368 and M874, Falcon 900 aircraft serial numbers 60 through 187 that do not incorporate modification M3368, and Falcon 900EX aircraft that do not incorporate modifications M3368 or service bulletin F900EX-142. The directive mandates that these aircraft must incorporate a support assembly for the baggage compartment fire extinguisher discharge nozzle. This requirement is detailed in the directive as being in accordance with Dassault Aviation Service Bulletin F900-279 Revision 1 (Mod M3368 and Mod M874) for Mystere Falcon 900 aircraft and Dassault Aviation Service Bulletin F900EX-142 for Mystere Falcon 900EX aircraft.
The obligations imposed on the parties governed by this directive are clear and straightforward. Owners and operators of the specified Mystere Falcon 900 aircraft must ensure that the required modifications are incorporated within the stipulated timeframe. This involves following the instructions provided in the referenced Dassault Aviation service bulletins. Compliance with the AD is mandatory and must be achieved within 330 flight hours after the effective date of the directive, but no later than 8 February 2003. Failure to adhere to these requirements could result in serious safety risks, as the directive is issued to correct an unsafe condition that could lead to inadequate fire suppression in the event of a baggage compartment fire.
Failure to comply with the provisions of this AD may lead to significant legal and safety consequences. Under the Civil Aviation Regulations 1998, non-compliance could result in civil penalties, including fines and potential legal action. Additionally, the AD could lead to grounding of the aircraft until the required modifications are made, which could have serious operational and financial implications for the aircraft owners and operators. The maximum penalties for non-compliance are not explicitly stated in the directive but are subject to the general provisions of the Civil Aviation Regulations 1998, which can include substantial fines and other regulatory actions.
