|---|
| 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. |
