On December 21, 2023, a serious aviation incident occurred at Tokyo-Haneda Airport when an Airbus A350-941 (JA13XJ) collided with a Japan Coast Guard DHC-8-315Q MPA aircraft (JA722A). The DHC-8, en route to Niigata, was instructed to taxi onto runway 34R via taxiway C5. After touchdown, the A350 struck the DHC-8, causing significant damage to the A350’s nose section. The collision resulted in a fire, injuries, and the evacuation of all occupants. The surviving captain of the DHC-8 and five crew members were hospitalized, while one passenger suffered a crack in their rib, another a bruise, and the third experienced a sprain. A month later, a passenger’s bone bruise on their shin bone was reported. The Ministry of Land, Infrastructure, Transport and Tourism reported that the A350 had been cleared to land on runway 34R, while the DHC-8 was instructed to hold short on taxiway C5. However, the ATC record indicated that the stop bar lights for taxiway C5 were unserviceable, contradicting the captain’s assertion of takeoff clearance. This discrepancy raises questions about the incident’s sequence of events and potential errors in communication.On December 21, 2023, a serious aviation incident occurred at Tokyo-Haneda Airport when an Airbus A350-941 (JA13XJ) collided with a Japan Coast Guard DHC-8-315Q MPA aircraft (JA722A).
