Dassault Falcon 7X planes must replace a faulty part that can cause hydraulic leaks

The US aviation regulator is ordering all Dassault Falcon 7X airplanes to replace a specific electrical control unit. This unit can cause a standby pump to overheat and leak hydraulic fluid, which is a safety risk.

This is a mandatory safety fix for a specific model of business jet. It means every owner and operator of a Dassault Falcon 7X must now schedule maintenance to replace this part. The cost of the replacement and associated downtime will be borne by the aircraft owners.
