Northwest Flight Experienced Airspeed Fluctuations
Additional details about Northwest Airlines Flight 8 from Hong Kong to Tokyo that experienced airspeed fluctuations were released in a National Transportation Safety Board (NTSB) preliminary report on Tuesday.
The Northwest Airlines Airbus 330 reportedly experienced airspeed fluctuations while in cruise flight. According to reports, after entering an area of turbulence and moderate rain, the autopilot and autothrust switched off. After a period of a minute, during which the crew reportedly followed flight manual procedures, the autopilot returned but was soon followed by another two minute outage.
The crew reportedly observed large airspeed anomalies, altitude fluctuations and an overspeed alert.
The flight landed in Tokyo without any damage or injuries to the crew or passengers.
The investigation was handed on to the NTSB by the Japanese Transportation Safety Board.
