(1) Date and Location: 3/Feb/2021, Hiroshima pref., Osakikamijima-cho, Toyota District, Hiroshima Prefecture.
(2) Damages: No casualties, No property damages.
(3) Summary: During a drone logistics demonstration experiment held in Osakikamijima-cho, Toyota District, Hiroshima Prefecture, the failsafe emergency landing function was triggered twice during the drone’s automatic navigation, resulting in a sudden loss of altitude and emergency landing. The first time the failsafe function was triggered was thought to be due to a physical shock at sea. The second triggering of the fail-safe function was due to a human error by our operator in setting the values for the flight. The crash site was in the vicinity of a high voltage power line, but the results of an investigation by an external organization did not indicate any evidence of contact.
(4) Reoccurrence Prevention Measures: Drone operators will be required to undergo regular training, and the functions of the drone will also be enhanced to reduce risk of reoccurrence.
