In January of 2024 a Japan Airlines A350-900 was landing on runway 34R at the Haneda airport collided with a Japan Coast Guard DHC-8 that was lined up on the runway. All 379 people on the A350 evacuated safely, while five of the six on the DHC-8 were killed. The survivor of the JCG aircraft said that he thought he was cleared to enter the runway, while the instruction was for them to hold short at taxiway C5 (runway 34R is known as runway C). According to the update released, the Runway Occupancy Monitoring Support Function activated in on the controllers display, but there are no regulations or training on how to handle alerts from the system, and it's frequently ignored.
Another problem identified was that the runway lights, and the rear lights on the DHC-8 were all white. The crew didn't identify the aircraft on the runway until the last minute, too late to go around. Tests were completed in March using a helicopter and Dash 8 at Aichi, which has similar lighting conditions as Haneda. A detailed analysis is being performed of the tests.

Quote:The Japan Transport Safety Board released a progress report on the investigation into the January 2024 collision at Haneda Airport between a Japan Airlines plane and a Japan Coast Guard (JCG) plane on the morning of the 25th.
The report pointed out a commonality with past aviation accidents in that the system that detects and notifies air traffic controllers of erroneous runway incursions was not effectively utilized. Based on the analysis of causes to date, the board will compile measures to prevent recurrence and mitigate damage.
This is the first time that the Japan Transport Safety Board has released two progress reports before issuing a final investigation report. The progress report released in December last year pointed out that the accident was caused by a combination of three factors:
- the JCG plane believed it had received permission and entered the runway for takeoff;
- the air traffic controllers did not recognize the JCG plane's approach; and
- the JAL plane, which was landing, did not recognize the JCG plane until just before the collision.
