The National Transport Safety Commission has not shown on the radar about an accident in which an ANA passenger plane shook from Haneda Airport to Beijing, China, and seriously injured passengers and four flight attendants. We released an investigation report saying that it is highly likely that we were caught in the turbulence immediately after we encountered the cloud and turned on the seat belt sign.

In August, ANA's Boeing 787, which was heading from Haneda Airport to Beijing, suddenly shook while flying about 5,500 meters above China, causing serious injuries to two passengers and two flight attendants. Was slightly injured.

According to the Japan Transport Safety Board's investigation report, the pilot once took a route away from a place with many cumulonimbus clouds, but approached at the direction of a Chinese controller, and developed there, which was not displayed on the radar. It means that I encountered a cloud.

The pilot immediately turned on the seat belt sign because it was expected to shake, but 25 seconds later, it was likely that he was caught in eddy because the aircraft grabbed the developed clouds and shook greatly. It is said.

It means that we couldn't make an announcement to draw the attention of the passengers.

The Japan Transport Safety Board says that it is effective for pilots to give the controller as specific information as possible, such as the distance to a place with a lot of cumulonimbus clouds, in advance to make a decision.
