Incident at EDMONTON INTL AB (CYEG) (Navigation error, Navigation assistance, Conflict - loss of separation)


2003-08-27: UPDATE TSB reported that the Air Norterra (Canadian North) Boeing 737-200, was operating as flight MPE 447 from Yellowknife, NT to Edmonton, AB. While on vectors for the right hand approach to Runway 30 at Edmonton (CYEG), MPE 447 called the field in sight and requested the visual approach. The crew of MPE 447 then lost sight of the airport. Shortly after, the Arrival Controller noticed MPE 447 commencing a right turn towards the departure end of Runway 02. A Westjet 737-700 was departing off of Runway 02 and separation eroded to 1.5 NM in an area where 3 NM are required. Vectors were given to both aircraft to regain separation. There were no TCAS advisories from either aircraft. Visibility at the time of the occurrence was reported on the ATIS as 10 SM in smoke and the setting sun was in line with the airport and MPE 447.
2003-08-22: MPE 447, a B737, was being vectored for a right hand approach for Runway 30 at Edmonton International and the pilot advised he had the airport in sight so he was given a right hand visual for Runway 30. Shortly after this, WJA 655, another B737, departed from Runway 02 at the Edmonton International bound for Vancouver. At this time, the Arrival Controller noticed that MPE 447 had turned west and was heading right for the departing aircraft. The Departure Contoller turned WJA 655 to a heading of 270 degrees and the Tower turned MPE 447 to a heading of 200 degrees and then returned the aircraft to the Terminal Controller. At this point, separation had been re-established and no further incident occurred. The aircraft got to within 1.5 NM of each other (same altitude)in an area where 3 NM is the standard. No TCAS was reported by either aircraft.
