What it does

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This 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 AD requires modifying the maintenance and avionics interface computer (MAIC) software and revising the existing airplane flight manual (AFM) to provide improved procedures for addressing slat failures. The FAA is issuing this AD to address the unsafe condition on these products.
