Incident
at MOOSE JAW / AIR VICE MARSHAL C.M. McEWEN SK (CYMJ)
(ATS operating irregularity)
An ATC Operating Irregularity occurred when DRGN 65, a military CT-155 Hawk trainer from CFB Moose Jaw (YMJ), entered the Winnipeg ACC Great Plains Sector (GP) airspace before Moose Jaw TCU co-ordinated with GP. DRGN 65 had been cleared to the Yorkton airport via YMJ direct YQV to maintain FL 190. When YMJ pointed out DRGN 65 to GP, YMJ TCU was advised by GP to re-clear DRGN 65 to maintain 17,000 feet. GP then re-cleared WJA 210, a B737 inbound to Regina, to maintain FL 180. At that time JZA 8573, a Canadair RJ, was climbing out of Regina through FL 190 to FL 230.
UPDATE ANS and Airspace reported that Nav Canada plans no further action as this was a DND error.
