If a nut is found cracked the affected fuel line must be replaced with a serviceable fuel line of the correct type before further flight.
2 (b). Replace fuels lines that have end nuts that are blue or yellow in colour.
Note: DGAC AD 2001-131(A) refers.
Compliance: 1. Unless previously accomplished, before further flight after the effective date of this Airworthiness Directive.
2 (a). Unless previously accomplished, before further flight after the effective date of this Airworthiness Directive and thereafter at intervals not to exceed 20 flying hours.
2 (b). Within 30 days of the effective date of this Airworthiness Directive.
Installation of fuel lines of the correct type constitutes terminating action for this Airworthiness Directive.
This Airworthiness Directive becomes effective on 14 April 2001.

SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: This Directive is prompted by advice that the fuel lines located between the firewall and the engine may not comply with the aircraft type design. Non-compliant fuel lines have been found with cracked end nuts. Nut failure could result in an in-flight fire.

Delegate of the Civil Aviation Safety Authority 9 April 2001
The above AD is notified in the Commonwealth of Australia Gazette on 12 April 2001.
Overview
The Civil Aviation Regulations 1998, under Part 39 - 105, were enacted to ensure that aircraft operating in Australia meet stringent safety standards. One of the instruments under this legislation is the Airworthiness Directive (AD/F406/4) issued by the Civil Aviation Safety Authority (CASA) on 9 April 2001, targeting Reims F406 Series Aeroplanes with serial numbers F406-0001 to F406-0086. This directive was introduced to address a specific safety concern regarding the fuel lines located between the firewall and the engine. Non-compliance with the aircraft type design and the potential for cracked end nuts on these fuel lines posed a significant risk of in-flight fires. The policy objective of this AD is to mandate regular inspections and necessary repairs to mitigate these risks, ensuring the continued safe operation of the affected aircraft.
Scope and Application
The Civil Aviation Regulations 1998, under PART 39 - 105, establishes a framework for ensuring the safety of civil aviation in Australia, with specific regulations governing airworthiness directives. This particular Airworthiness Directive (AD) applies to Reims F406 aircraft with serial numbers ranging from F406-0001 to F406-0086. The directive mandates that fuel lines, specifically P/N AE 7013108 H 0155 and AE 7013108 G 0105, which are located between the firewall and the engine, must be inspected. The inspection requirements are detailed in REIMS AVIATION Service Bulletin CAB01-6 dated 26 March 2001. If the nuts on the end of the fuel lines are black or grey, no further action is necessary; however, if the nuts are blue or yellow, they must be checked for cracks. If any cracks are found, the affected fuel line must be replaced with a serviceable one of the correct type before further flight. The directive becomes effective on 14 April 2001, and compliance must be achieved before further flight, with specific intervals for inspection and replacement. This AD ensures that all affected Reims F406 aircraft maintain airworthiness standards and mitigates the risk of in-flight fire due to potential fuel line failures.
Key Provisions
The Airworthiness Directive (AD) AD/F406/4 issued by the Civil Aviation Safety Authority (CASA) under section 39.1(1) of the Civil Aviation Regulations 1998 pertains specifically to Reims F406 aircraft with serial numbers F406-0001 to F406-0086. This directive mandates inspections and actions concerning the fuel lines located between the firewall and the engine to address potential safety risks. Under section 6(2)(a) of the AD, fuel lines P/N AE 7013108 H 0155 and AE 7013108 G 0105 must be inspected. If the nuts at the ends of these fuel lines are black or grey, no further action is required, but an entry must be made in the aircraft logbook, and the aircraft can be released for service. However, if the nuts are blue or yellow, further action is necessary. Specifically, section 6(2)(b) of the AD requires that these nuts be inspected for cracks as per REIMS AVIATION Service Bulletin CAB01-6 dated 26 March 2001. If any cracks are found, the affected fuel line must be replaced with a serviceable fuel line of the correct type before further flight.
The AD imposes several obligations on the parties or entities it governs. Primarily, it mandates that fuel lines on specified Reims F406 aircraft must be inspected and, if necessary, replaced to meet safety standards. The directive sets specific timelines for compliance: inspections must be carried out before further flight after the effective date of the AD, and replacements must be completed within 30 days of the AD's effective date. Additionally, ongoing inspections at intervals not exceeding 20 flying hours are required for fuel lines with blue or yellow nuts. These obligations ensure that aircraft maintain the necessary safety standards and reduce the risk of in-flight incidents.
The AD also includes provisions for penalties and consequences for non-compliance. While the AD itself does not specify exact penalties, non-compliance with CASA directives generally results in significant consequences under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998. Failure to comply with ADs can lead to enforcement actions, including fines and potential criminal charges. Additionally, operating an aircraft that does not meet the required airworthiness standards poses significant safety risks and can result in grounding of the aircraft, which can have severe operational and financial impacts on the operator. Compliance with these directives is therefore critical to maintaining the safety of civil aviation operations.
