Incident at Vicinity of Truro NS


1997-09-03: ARN842 DH8 enroute Charlottetown to Halifax as aircraft entered Halifax Terminal Control Area started a descent through 11,000 feet. A conflict occurred when a Canadian Forces CP140 Aurora was observed transiting the area at 10,500 feet under Visual Flight Rules. The Aurora spotted the DH8 and took avoiding action. The DH8 crew advised that they saw the Aurora only at the last minute and were unable to take avoiding action. Initial indications are that the Aurora did not have their transponder turned on. This is possibly why ARN842 did not get the TCAS warning. TSB case closed. Action by Enforcement
