The FAA and NTSB are investigating an uncommon rolling movement of a Southwest Airways Boeing 737 Max

WASHINGTON (AP) — Federal officers stated Thursday they’re investigating an uncommon rolling movement on a Southwest Airways Boeing 737 Max which may have been attributable to a broken backup power-control unit.

The Federal Aviation Administration stated it was working with Boeing and the Nationwide Transportation Security Board to research the Could 25 incident, which occurred on a flight from Phoenix to Oakland, California.

The FAA stated the aircraft went right into a “Dutch roll,” the title given to the mixture of a yawing motion when the tail slides and the aircraft rocks from wingtip to wingtip. It’s stated to imitate the motion of a Dutch ice skater.

Pilots are educated to get well from the situation, and the Southwest aircraft landed safely in Oakland. There have been no accidents reported among the many 175 passengers and 6 crew members.

Based on a preliminary report by the FAA, an inspection after the aircraft landed confirmed harm to a unit that gives backup energy to the rudder.

The FAA stated different airways haven’t reported related points.
