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.
AD 2011-0169 is a follow up to an earlier AD that allowed the majority of the Falcon 7X fleet to resume flight operations in July.
