Incident at CALGARY INTL AB (CYYC)
2005-02-04: ACA 140, an A320, departed Calgary for Toronto and the crew was assigned and read back a heading of 010 degrees, to pass behind opposite-direction traffic, NCB 314, a Cessna 441 arriving from the north. The crew reportedly dialed in a heading of 100 degrees by mistake. As ACA 140 was going through heading 070 degrees, a correcting heading of 010 degrees was ordered and NCB 314 was instructed to descend expeditiously to 7,000 feet. Separation eroded to 2.7 NM laterally and 600 feet vertically where 3 NM and 100 feet were required. TSB will be looking into the loss of separation.
2005-02-22: UPDATE TSB reported that the Air Canada Airbus A320-200, C-FKAJ, was operating as ACA 140 from Calgary, AB to Toronto, ON. During the initial climb to 9,000 feet, ATC instructed ACA 140 to turn to a heading of 010 degrees. The readback was correct, however, a heading of 100 degrees was entered into the flight control unit (FCU) by the flight crew. As ACA 140 passed through 7,000 feet, the Controller instructed ACA 140 to fly a heading of 010 degrees and directed an inbound North Cariboo Flying Service Cessna 441 to expedite their descent through 7,000 feet. A loss of separation occurred when separation eroded to 2.7 NM laterally and 600 feet vertically where 3 NM or 1000 feet were required.
