On 13 November 2012, a Garuda Airbus A330 and a KLM Boeing 737 lost separation against each other whilst correctly following radar vectors to parallel approaches at Amsterdam but there was no actual risk of collision as each aircraft had the other in sight and no TCAS RA occurred. The Investigation found that one of the controllers involved had used permitted discretion to override normal procedures during a short period of quiet traffic but had failed to restore normal procedures when it became necessary to do so, thus creating the conflict and the ANSP was recommended to review their procedures.
