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 39.001(1) of CASR 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.
Dassault Aviation Falcon 2000 Series Aeroplanes
AD/F2000/27
Wing Anti-Ice Monitoring System
7/2007
Applicability:
Falcon 2000EX aeroplanes, serial numbers 1 to 5 and 7 to 27 inclusive, without
Dassault Aviation Modifications M2814 and M2949 incorporated.
Requirement:
Unless previously accomplished, modify the electrical wiring of the wings anti-ice
system in accordance with the accomplishment instructions of Dassault Aviation
Service Bulletin (SB) F2000EX-116 dated 31 May 2006 and F2000EX-140 dated
28 February 2007, or later revisions approved by the European Aviation Safety
Agency (EASA).
Note: EASA AD 2007-0137 refers.
Compliance:
Within the next six months after the effective date of this Directive.
This Airworthiness Directive becomes effective on 5 July 2007.
Background:
EASA has advised that analyses of in-service reports revealed that in instances of
failure of the wings anti-ice valve, indications of untimely anti-icing with the wings
anti-ice selector on “OFF" or of insufficient anti-icing with the wings anti-ice selector
on “AUTO" might not be properly displayed to the flight crew. It may result, on
ground, in potential structural damages due to a leading edge overheat, or in-flight, in
an insufficient anti-ice power.
This Directive mandates an upgrade of the wing anti-ice monitoring circuitry per
implementation of modifications M2814 (SB F2000EX-116) and M2949 (SB
F2000EX-140) to cover the whole monitoring logic of the wings anti-ice system.
