On 30 November 2019, as an Airbus A320 was about to touchdown in normal night visibility at Toyko Haneda, a runway maintenance contractor’s small car began to cross the same runway without obtaining the required clearance as the driver believed this was not necessary. Separation reduced to 1,417 metres shortly before the A320 began to clear the 3,000 metre runway. Planning for overnight work on the intersecting runway was found to have been inadequate and multiple related training requirements and procedures were enhanced by both the aviation regulator and the airport operator. The incursion was assessed as ICAO Category ‘C’.
