Incident at 25NM SW COMOX BC (CYQQ)

Aviation Incident Report#13968: An American privately-registered Lancair Lancair IV-P from Campbell River, BC (CYBL) to Hillsboro, OR (KHIO) on a VFR flight and contacted Comox Terminal above 13,000'' (in Class B airspace) in the climb, requesting the highest altitude they could climb to VFR. The aircraft was advised that 12,500'' was the highest VFR altitude and that only CVFR or IFR were authorized above 12,500''. The aircraft continued its climb after acknowledging the controller and advising they were going to descend to 12,500?, and reached 15,700? when the controller again instructed the aircraft to descend and issued a ?do not exceed 16,000?? instruction. The aircraft took an excessively long time descending back to VFR altitude and required repeated instructions from the controller. The aircraft left the Comox Military Terminal Control Area (MTCA) into Vancouver Anahim's airspace still above 12,500, and their controller experienced the same issue in attempting to have the aircraft descend to a VFR altitude.

June 25, 2002

Incident at 30 NM E of SWIFT CURRENT SK (CYYN)

ACA 6606, a B737, was enroute from Vancouver to Regina and 30 NM east of Swift Current when the crew deviated from their flight plan for unknown reasons. As a result, the flight had less than the appropriate separation from Moose Jaw airspace. The Sector Controller issued the crew a heading that prevented a penetration into restricted airspace. TSB will be checking into the occurrence.
UPDATE TSB reported that the Boeing 737-200, C-GJCP operated by Air Canada as flight ACA 6066, was east of Swift Current and descending through FL 322 en route to Regina when the Great Plains Sector Controller observed the flight was south of the cleared route. The Controller asked the crew to confirm they were navigating on J500; the crew replied they were routing direct to Regina. The Controller advised them their clearance was J500 to Lumsden and instructed them to turn left 25 degrees. The crew turned as instructed. The spacing between ACA 6066 and the Moose Jaw military Terminal Control Area was reduced to a minimum of 1.5 NM horizontal and zero vertical before the separation standard in effect of 5 NM horizontal or 2,000 feet vertical was re-established. No other aircraft were in the vicinity; however, a loss of separation occurred between ACA 6066 and the Moose Jaw MTCA airspace.

March 10, 2002


Demon 85, an P3 working Greenwood MTCA was unable to land at Greenwood due crosswinds. Requested a clearance to Halifax.

Incident at MOOSE JAW / AIR VICE MARSHAL C.M. McEWEN SK (CYMJ) (ATS operating irregularity)

UPDATE TSB reported that the Boeing 727-100 operated by All Canada Express as flight CNX 706, was northwestbound at FL 310. Moose Jaw TCU contacted Winnipeg ACC at about 0730 and advised that they would be taking control of the Moose Jaw MTCA airspace at 0800 under the provisions of the ATC inter-unit agreement. The current agreement caps the airspace at FL 310; the previous agreement capped the airspace at FL 280. The Lumsden Sector Controller forgot that the airspace cap had been raised and allowed CNX 706 to enter the Moose Jaw MTCA at 0750 at FL 310 without coordination with the Moose Jaw TCU. The flight exited the MTCA at 0804. The separation standard in effect required 2000 feet vertical spacing above the Moose Jaw MTCA. Radar data analysis revealed that the aircraft closest to CNX 706 during this period was at 17,000 feet.
At 1230Z, Moose Jaw Terminal Control contacted Winnipeg ACC to co-ordinate the activation of the Military Terminal Control Area (Vertical dimensions up to FL 310) At 1250Z, CNX 706, a B727, overflew the MTCA at FL 310 without co-ordination or the required separation. The aircraft cleared the MTCA at 1304Z. No known conflictions.
UPDATE ANS and Airspace reported that NAV CANADA will convene a Fact Finding Board.
