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.
AMD Falcon 50 and 900 Series Aeroplanes
AD/AMD 50/29 Fuselage Lateral Feeder Tanks 3/2003
Applicability: Mystere Falcon 50 aeroplanes, excluding those aircraft incorporating Dassault Aviation Service Bulletin F50-415, modification M673, or modification M2491.
Requirement: Carry out the requirements of Dassault Aviation Service Bulletin F50-415.
Note: DGAC 2002-595(B) refers.
Compliance: Within 15 months from the effective date of this Directive.
This Airworthiness Directive becomes effective on 20 March 2003.
Background: Analysis of an in-flight incident has shown the need to improve the resistance of the feeder tanks skin to direct lightning effects. This Directive addresses the problem by the fitment of insulation patches to the internal side of the feeder tanks.

Delegate of the Civil Aviation Safety Authority 28 January 2003
The above AD is notified in the Commonwealth of Australia Gazette on 26 February 2003.
Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to ensure the safety of civil aviation in Australia. One of the specific issues addressed by the regulations is the need to enhance the safety of aircraft through Airworthiness Directives (ADs). The AD/AMD 50/29, issued on 3 March 2003, pertains to the Mystere Falcon 50 aeroplanes and mandates improvements to the fuselage lateral feeder tanks to mitigate the risk of damage from direct lightning effects. This Airworthiness Directive was issued by the delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of CAR 1998, following an analysis of an in-flight incident that highlighted the need for enhanced tank resistance. The policy objective of this directive is to ensure that the specified aircraft meet the necessary safety standards by implementing the requirements outlined in Dassault Aviation Service Bulletin F50-415. This directive became effective on 20 March 2003, with a compliance period of 15 months from the effective date.
Scope and Application
This Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998, specifically part 39, applies to Mystere Falcon 50 aeroplanes excluding those aircraft that have already incorporated the modifications detailed in Dassault Aviation Service Bulletin F50-415, modification M673, or modification M2491. The directive mandates the implementation of the requirements outlined in Dassault Aviation Service Bulletin F50-415, which includes fitting insulation patches to the internal side of the feeder tanks to enhance resistance against direct lightning effects. This AD, which is effective from 20 March 2003, must be complied with within 15 months from its effective date. The directive applies nationally within the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA) and is applicable to all relevant aircraft within the specified timeframe, ensuring adherence to safety standards set forth by CASA.
Key Provisions
The Airworthiness Directive (AD) issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 applies specifically to Mystere Falcon 50 aeroplanes, excluding those that have already incorporated Dassault Aviation Service Bulletin F50-415, modification M673, or modification M2491. This AD mandates that the requirements outlined in Dassault Aviation Service Bulletin F50-415 be followed. This bulletin, referenced as DGAC 2002-595(B), details the necessary modifications to improve the resistance of the fuselage lateral feeder tanks' skin to direct lightning effects. The modifications include the fitment of insulation patches to the internal side of the feeder tanks. The directive requires compliance within 15 months from its effective date of 20 March 2003.
The AD imposes clear obligations on the operators of Mystere Falcon 50 aeroplanes that fall within its scope. These operators must adhere to the instructions provided in Dassault Aviation Service Bulletin F50-415 to ensure that the modifications are correctly implemented. This involves the installation of insulation patches to the internal side of the feeder tanks, which is crucial for enhancing the aircraft's resistance to direct lightning effects. Compliance with the AD is mandatory, and operators must ensure that the required modifications are completed within the stipulated timeframe of 15 months from the directive's effective date.
Failure to comply with this Airworthiness Directive can result in serious consequences. While the Civil Aviation Regulations 1998 do not explicitly state the penalties for non-compliance with ADs in this specific context, general aviation regulations imply that non-compliance can lead to severe repercussions. These may include civil penalties, enforcement actions by the Civil Aviation Safety Authority (CASA), and potential grounding of the aircraft until the required modifications are made. Additionally, non-compliance could result in criminal charges if it is deemed to have contributed to an aviation accident or incident, leading to significant legal and financial consequences for the operators.
