Accident: Southwest B38M enroute on May 25th 2024, Dutch Roll

By Simon Hradecky, created Wednesday, Jun 12th 2024 17:25Z, last updated Wednesday, Jun 12th 2024 17:25Z

The FAA reported: "AIRCRAFT EXPERIENCED A DUTCH ROLL, REGAINED CONTROL AND POST FLIGHT INSPECTION REVEALED DAMAGE TO THE STANDBY PCU, OAKLAND, CA." and stated the aircraft sustained substantial damage, the occurrence was rated an accident.

The aircraft remained on the ground in Oakland until Jun 6th 2024, then positioned to Everett,WA (USA), ATS facilities, and is still on the ground in Everett 6 days later.

Dutch Roll is a coupled out of phase movement of the aircraft as result of weakened directional stability (provided by the vertical tail and rudder), in which the aircraft oscillates around its vertical as well as longitudinal axis (coupled yaw and roll).

The PCU is the power control unit, an actuator controlling the (vertical) rudder.
