## Summary

We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes. This proposed AD was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. This proposed AD would require repetitive inspections of each anti-ice piccolo tube and corrective action if necessary. This proposed AD also provides an optional terminating action for the repetitive inspections. We are proposing this AD to address the unsafe condition on these products.
