What happened
Approximately twenty minutes following its takeoff from Tokyo-Haneda Airport, an aircraft entered an uncontrolled descent while cruising at 3,500 feet. The flight was operating under marginal weather conditions when the plane began a dive, ultimately impacting the ocean roughly 10 miles south of Oshima Island. Following the impact, the wreckage descended to a depth of 1,500 meters.
Of the 26 people on board, 25 fatalities were recorded, with only one passenger successfully rescued from the site. Reports from the sole survivor indicate that the aircraft encountered significant turbulence and thunderstorm activity during its flight path.
Findings
Prior to the loss of control, the cabin experienced several electrical malfunctions characterized by flickering lights. The investigation into the descent suggests the aircraft was navigating adverse weather and thunderstorm activity at the time of the accident.
