Incident at EDMONTON / VILLENEUVE AB (CZVL) (Navigation error, Conflict - near collision (VFR or IFR))

Summary

2003-03-31: UPDATE TSB reported that the solo student pilot of the Namao Flying Club Cessna 150L, C-FTKK, was practicing touch and goes at Villeneuve, AB, with the instructor observing in the Tower. While on downwind for Runway 34, the Cessna was instructed to follow an Edmonton Flying Club Piper PA 28-161, C-GVZJ, that was on left base for a touch and go; the student replied that he had the traffic in sight. On final approach was a Mooney that was performing a full stop landing. The Cessna then turned left base parallel and inside of the Piper. Another Edmonton Flying Club aircraft in the circuit remarked on the frequency that the two aircraft were very close. The Piper was slowing to allow room for the Mooney to exit off of Runway 34 when the Tower Controller issued missed approach instructions to the Piper to ease off to the right, pull up, and go around. At that time the Piper was overflown by the Cessna by less than 25 feet. The Piper manoeuvred to the left to avoid the Cessna and then climbed to rejoin the circuit on the downwind. The Cessna was also given missed approach instructions by the Tower. There were 4 aircraft in the circuit at the time of the occurrence. There is no radar display in the Nav Canada Control Tower at Villeneuve.
2003-03-28: C-GVZJ, a Piper Cherokee with an instructor and student on board, and C-FTKK, a Cessna 150 with a student pilot at the controls, were both on final approach to Runway 34 at Villeneuve. The Controller had reportedly given the student pilot 2 or 3 traffic advisories and the pilot had acknowledged that he had the traffic in sight. The pilot of C-FTKK subsequently misunderstood an ATC instruction to turn right for spacing, as an instruction to climb, and as a result, came within 15 feet of C-GVZJ. The Cessna 150 pilot was a student pilot on his second solo flight and his instructor was in the Tower cab at the time. A preliminary investigation within Nav Canada is in progress to confirm the Controller's instruction, however initial information suggests no Controller involvement in the near collision. Villeneuve Tower also has no radar capability and on occasion, it is difficult for the Controllers to determine exactly how far apart small a/c are. The Tower has been waiting for quite some time for a radar feed from Centre, but the installation has been delayed.
