Incident at GRANDE PRAIRIE AB (CYQU) (TCAS alert, Conflict - potential)

Summary

2005-02-24: Both JZA 8146, a DHC-8 and C-FUEF, a Beech Bonanza, were inbound for Runway 25 at Grande Prairie. When the airport advisory was issued by FSS, the pilot of C-FUEF agreed to follow JZA 8146. C-FUEF then turned to the right to give way to JZA 8146. When on radar at 2 miles apart, FSS queried the pilot of C-FUEF if he had JZA 8146 visual. The pilot of C-FUEF located the traffic at his 1 o'clock at which time the pilot stated he adjusted his altitude and turned to avoid the traffic. Soon thereafter the crew of JZA 8146 reacted to a TCAS RA and climbed 800 feet. Radar playback shows approximately 0.5 mile between the aircraft at 6 miles east of the airport reference point.
2005-03-01: UPDATE TSB reported that the Beech F33A aircraft, registration C-FUEF, was approaching Grande Prairie from the south and had contacted FSS on the MF frequency and was set up for a left base for Runway 25. An inbound Air Canada Jazz Dash 8-100, flight JZA 8146 from Edmonton, then reported on the MF and was due to arrive at approximately the same time as the F33A. The pilot of the F33A, believing that the Dash 8 was behind him, advised that he would turn right to extend his downwind to allow the Dash 8 to land first. This turn resulted in the Dash 8 receiving a TCAS RA to climb. The Dash 8 climbed 800 feet and the F33A descended and increased the rate of turn to avoid the Dash 8. The aircraft came within 0.5 NM of each other approximately 6 NM east of the airport.
