On 6 February 2013, ATC mismanagement of an Airbus A320 instructed to go around resulted in loss of separation in IMC against the Embraer 190 ahead which was obliged to initiate a go around when no landing clearance had been issued due to a Boeing 737-800 still on the runway after landing. Further ATC mismanagement then resulted in a second IMC loss of separation between the Embraer 190 and a Boeing 717 which had just take off from the parallel runway. Controller response to the STCA Alerts generated was found to be inadequate and ANSP procedures in need of improvement.
