Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG) (Incursion - runway - aircraft, Conflict - potential, ATS operating irregularity)


2001-05-22: TGO 985, a DHC-6 Twin Otter, landed on Runway 18 at Winnipeg and the crew was instructed to exit onto Runway 25 westbound, as the exit point for the direction the Tower assumed the crew wanted to go. Tower also had BLS 363, a Beech 99, on final for Runway 25 and told the crew of TGO 985 to ""keep it rolling westbound"" on Runway 25 as BLS 363 was going to land once TGO 985 was clear. BLS 363 was given landing clearance for Runway 25 with instructions to hold short of Runway 18 in conjuction with other traffic on Runway 18. Tower then observed that TGO 985 had stopped and turned around west of Runway 18, but still on Runway 25. Repeated calls to TGO 985 by both Tower and Ground were unsuccessful. The Tower Controller did not pull up BLS 363 as he had SIRO set up for BLS 363 to hold short of Runway 18. TGO 985 finally came up on Ground frequency and advised they had wanted to go to Apron 1 for a passenger drop-off.
2001-06-11: UPDATE ANS and Airspace reported that the flight crew was attempting to enable one of their crew members to connect with a West Jet flight scheduled to depart 20 minutes after the Twin Otter's arrival time. Prior to switching to Winnipeg Tower for landing clearance, Winnipeg Terminal Control was requested to advise the air carrier that a passenger would be arriving with a minimum connection time, and the crew indicated to Terminal that they were planning to deplane the passenger at Gate 6 on Apron I. Terminal advised that they would pass the information on to the control tower and later confirmed that the information would be passed to the airline's flight crew. When instructed to clear right on Runway 25 and contact Ground, none of the 3 pilots on board the aircraft heard the request to ""keep it rolling westbound"". Instead it was expected that Tower intended to clear the DHC-6 back across Runway 18 to Apron I when traffic permitted. As soon as the Twin Otter cleared off of Runway 18 westbound, the aircraft was turned around and stopped behind the hold line. (At this point it was approximately 700 feet beyond the hold line for Runway 25 on the east side of Runway 18, as used for SIRO operations). Simultaneously, frequencies were switched in order to contact the ground controller. After a short pause without a response from ground the flight crew realized the wrong frequency had been selected. At the same time they noticed the Bearskin flight landing towards them but on the opposite side of Runway 18 which was also active with other arriving and departing aircraft. Ground Control was then contacted and the DHC-6 was subsequently cleared across Runway 18 towards Apron I. A review of the Tower tapes later confirmed that the Tower had instructed TGO 985 to ""keep it rolling westbound"". Information on this incident has been forwarded to TC Aircraft Services Directorate Safety Officer for follow-up action.
