Incident at vicinity of 52N 50W

Summary

2014-12-16: A Delta Airlines Airbus A330-300 (DAL32) from Atlanta, GA (KATL) to Amsterdam, The Netherlands (EHAM) at FL360 on an oceanic reroute, reported 52N 50W at 0448Z and indicated 52N 40W as the next position whereas 54N 40W was the expected position. Gander Ocean asked the pilot to confirm 40W and DAL32 verified on course to 54N 40W. Within 5 minutes of the 40W coordinate confirmed, Gander received two additional periodic reports indicating DAL32 was off course. DAL32 was asked again to confirm 40W. Pilot once again confirmed 54N 40W. Within another 5 minutes, Gander Ocean advised DAL32 of another position report error and asked if they were headed to 52N 40W. Pilot indicated they had a NAV error and advised they were turning back to 54N 40W. A loss of longitudinal separation occurred with two other aircraft, one, an Air France Boeing 777 200 (AFR689) from Atlanta (KATL) to Paris, FRA (LFPG) on the adjacent track south of DAL32's cleared track, and one, a Delta Air Lines Boeing 767 400 (DAL5) from New York, NY (KJFK) to London, UK (EGLL) on DAL32's cleared track but joining at 40W after deviation discovered.
