On 5 July 2014, an Airbus A340-300 taxiing for departure at Barcelona was cleared across an active runway in front of an approaching Boeing 767 with landing clearance on the same runway by a Ground Controller unaware that the runway was active. Sighting by both aircraft resulted in an accelerated crossing and a very low go around. The Investigation noted the twice-daily runway configuration change made due to noise abatement reasons was imminent. It was also noted that airport procedure involved use of stop bars even on inactive runways and that their operation was then the responsibility of ground controllers.
