Description

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Falcon 7X airplanes, effective July 9, 2026, to address unsafe conditions related to failed extension of the inboard slats during landing, which the crew alerting system did not indicate. The AD requires modifying the maintenance and avionics interface computer (MAIC) software and revising the airplane flight manual (AFM) to provide improved procedures for addressing slat failures. This action aims to prevent reduced lift margin and loss of control during approach and landing. The directive is an interim action and may be expanded in the future.
