## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by a report of a failed extension of the inboard slats during the landing phase, which the crew alerting system (CAS) did not indicate to the flightcrew. This proposed AD would require modifying the maintenance and avionics interface computer (MAIC) software and revising the existing airplane flight manual (AFM) to provide improved procedures for addressing slats failures. The FAA is proposing this AD to address the unsafe condition on these products.
