Nikko Aircraft swaying crew accident caused by turbulent air in clear weather
Last year, a Japan Airlines passenger aircraft heading for Haneda from New Chitose suddenly shook the aircraft, and one of the cabin crew members who crashed broke his left leg. An investigation report was published that the possibility of an accident due to turbulence was high.
In June of last year, a Japanese Airlines Boeing 777 aircraft heading for Haneda from New Chitose suddenly shook in the air over Miyagi Prefecture, causing one female flight attendant to be injured by breaking the ankle of his left leg.
According to the report of the Japan Transport Safety Board, which investigated the cause of the accident, the pilot determined from the weather forecasts, etc. that the turbulent swaying should be avoided by lowering the altitude and approaching the airspace where turbulence is possible. It is said that the warning was not given to the flight attendant.
However, the aircraft fluctuated greatly, and the cabin crew who had been performing in-flight services could not hold onto a nearby seat and fell down.
The report concludes that there is a high probability that an accident occurred due to the stormy turbulence that was stronger than expected.
In many cases, turbulence in clear weather cannot be visually confirmed and is not reflected in weather radar, so it suddenly encounters, so the Japan Transport Safety Board can predict shaking to prevent similar accidents. In some cases, the pilot points out that it is useful to provide information to flight attendants as appropriate.
