Tokyo, Japan: An All Nippon Airways (ANA) flight arriving from Shanghai carried out a precautionary go-around during its approach to Tokyo Haneda Airport on Tuesday morning after the aircraft’s onboard Traffic Collision Avoidance System (TCAS) issued a Resolution Advisory, prompting the flight crew to discontinue the landing and climb away.
Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) confirmed that one of the ministry’s Civil Aviation Bureau flight inspection aircraft had departed from Haneda’s Runway D and was operating in the vicinity when the TCAS alert occurred. The ministry said it is investigating the circumstances surrounding the event.
The incident involved ANA Flight NH968, operating from Shanghai Pudong International Airport to Tokyo Haneda Airport, at approximately 6 a.m. local time on August 4. According to ANA, the pilots followed the TCAS instruction as designed, executing an immediate climb before later returning to land safely. No injuries were reported among passengers or crew, and the aircraft landed without further incident.
Flight-tracking data published by Flightradar24 indicated that NH968 was on final approach to Haneda’s Runway C while the Civil Aviation Bureau aircraft had departed from the intersecting Runway D shortly beforehand. The available tracking data showed the two aircraft operating in close proximity, although authorities have not released the minimum separation distance or determined whether air traffic separation standards were breached.
Japanese media reported that the inspection aircraft departed as the ANA flight was established on approach, resulting in the collision avoidance system issuing its warning. However, aviation authorities have not yet published a preliminary investigation report detailing the sequence of events or identifying any operational errors.
The incident did not result in damage to either aircraft, and airport operations continued after the go-around. Authorities have not announced whether the occurrence will be classified as a serious incident or whether a formal safety investigation will be conducted by the Japan Transport Safety Board. At the time of publication, Japanese authorities had not released further findings, and the investigation remains ongoing.
