Singapore Changi Airport experienced a tense safety moment on August 28, 2024, when a China Eastern Airlines Boeing 777-300ER crew failed to respond to a vital go-around instruction, which nearly resulted in a runway incursion with another aircraft.
The Transport Safety Investigation Bureau’s final report detailed that two China Eastern aircraft arriving from Shanghai Pudong were involved: a Boeing 777-300ER and an Airbus A320neo. The Airbus landed first on Runway 20R and was instructed to vacate via exit 7. However, traveling at a speed too high to safely use exit 6, the A320neo had to brake sharply before turning onto exit 7.
At the same time, the Boeing 777 had been cleared to land on the same runway. Observing the reducing separation, air traffic control ordered the A320neo to vacate the runway promptly and directed the 777 crew to execute a go-around when the aircraft was just 76 feet above ground level and 296 meters from the runway threshold.
The 777 crew did not acknowledge the go-around instruction and proceeded with the landing. The airport’s Advanced Surface Movement Guidance and Control System immediately alerted the controller with visual and audio warnings. Fortunately, the A320neo had already cleared the runway edge, preventing a potential collision. Both aircraft continued taxiing safely to their terminals with no further issues.
Investigations indicated that the 777 crew likely missed the go-around call because of simultaneous altitude alerts from the aircraft’s Enhanced Ground Proximity Warning System (EGPWS), which may have masked the controller’s transmission. Additionally, the go-around instruction immediately followed a call to the A320neo crew, possibly adding to the communication confusion.
Following the incident, Singapore’s Civil Aviation Authority reminded controllers to issue go-around commands promptly when separation concerns arise. The event has been incorporated into operational training as a case study, while China Eastern alerted its pilots to be especially vigilant in responding to low-altitude go-around instructions.
In a related event on July 20, 2025, a Singapore Airlines Boeing 787-10 Dreamliner overran the runway during landing at Tokyo Narita Airport’s Runway 16L. Flight SQ638 had landed at about 15 knots ground speed but rolled past the threshold, coming to rest in the runway end safety area designed to mitigate overrun risks. Emergency and ground crews responded quickly, towing the aircraft back to a safe location about 40 minutes later. No injuries or technical faults were found, though the return flight was delayed by approximately 3.5 hours.
Runway 16L, at 2,500 meters in length, is shorter than other primary runways at Narita, and under certain weather and operational conditions, can present challenges for wide-body aircraft like the Boeing 787-10. The incident underscores the importance of runway length, braking performance, and environmental factors in landing operations and remains under investigation.
Both incidents highlight the critical need for precise communication and strict adherence to safety protocols in busy international airports, emphasizing ongoing efforts to enhance aviation safety worldwide.
