Key Takeaways:

EASA has issued an Airworthiness Directive (AD) for the Falcon 7X fleet, requiring a modification to its fly-by-wire system to improve detection and reversion of horizontal stabilizer trim issues.
This AD, an interim measure, follows an earlier directive that returned most of the fleet to service after a runaway trim incident in May, with operators having approximately one year to comply.
Dassault emphasized that the incident was a singular, rare event in the Falcon 7X's operational history, with the aircraft maintaining flight envelope control and landing safely.

EASA has issued an airworthiness directive (AD) in response to the runaway trim incident that temporarily grounded the Falcon 7X fleet in May. Most of the fleet was shortly returned to service.

The new AD, developed in conjunction with Dassault, calls for a modification of the fly-by-wire system to allow for earlier failure detection and quicker reversion of the horizontal stabilizer trim system.
