Near-miss over Tokyo: ANA jet and inspection aircraft avoid collision

An All Nippon Airways (ANA) flight approaching Tokyo's Haneda Airport from Shanghai narrowly avoided colliding with a Japanese government inspection aircraft on Tuesday, according to reports from Japanese and Chinese media. The incident has sparked renewed attention on aviation safety, particularly the role of anti-collision technology, industry professionals based in China told the South China Morning Post.

ANA Flight NH968, a Boeing 767 carrying 197 passengers and crew, was descending towards runway C at around 6am local time when its Traffic Collision Avoidance System (TCAS) activated, warning of a potential collision with a Cessna 525C inspector jet operated by the Japan Civil Aviation Bureau (JCAB), a division of the transport ministry. The pilots followed the TCAS instructions and executed a course correction, climbing to avoid the other aircraft.

The inspection aircraft, known as Dr White, had taken off from runway D and was conducting checks on navigation and airport facilities before it turned and crossed the flight path of the descending ANA plane, Japanese media reported. Flight trajectory data indicated that the vertical separation between the two aircraft was just 20 metres (66 feet) when their paths crossed.

The ANA aircraft landed safely at around 6.10am, and no passengers or crew members were injured. The airline said there had been no imminent risk of collision and that the incident had been reported to the transport ministry, which was investigating. Neither ANA nor JCAB immediately responded to requests for comment from the South China Morning Post.

Industry professionals in China said the incident highlighted the importance of anti-collision technology and protocols, given that the inspection aircraft's system failed to provide a similar warning to the ANA plane's TCAS. They added that China has "stringent" measures and systems in place to make such occurrences "less likely", since aviation safety would be critical to Beijing's ambitions in the sector and the future of its home-grown airliners.

The near-miss is the latest aviation safety incident at Haneda Airport, following a deadly runway collision in 2024.
