1996-04-22: A loss of separation occurred approximately 12 nautical miles north-west of Regina, Saskatchewan, between Prairie Flying Service flight 133, a Cessna 401A on a scheduled passenger flight from Regina to Lloydminster, Saskatchewan, and Sun Country Airlines flight 841, a Boeing 727 on a scheduled passenger flight from Regina to Saskatoon, Saskatchewan. Prairie 133 (C-401) departed runway 31 at Regina at 2109Z and turned to and climbed on an Air Traffic Control heading of 260 degrees. Sun Country 841 (B-727) departed runway 31 at Regina at 2112Z and was cleared to climb on a heading of 305 degrees. Sun Country 841 began a left turn to a heading of approximately 260 degrees shortly after takeoff. Air Traffic Control instructed Sun Country 841 to turn right to a heading of 310 degrees and received no response. Air Traffic Control then instructed Sun Country 841 to turn right to a heading of 360 degrees, and the crew acknowledged the instruction and turned as instructed. During the turn, the two aircraft passed within one mile horizontal and 200 feet vertical separation. After the crew members of Sun Country 841 made the left turn, they reportedly used TCAS to help ensure separation from Prairie 133. Neither aircraft took evasive action.
