Description

On 4 August 2014, a DHC8-400 (C-FOEN) being operated by Westjet Encore on a scheduled domestic passenger flight from Winnipeg to Thunder Bay as WEN3112 continued taxiing beyond the holding point for an expected intersection departure from runway 36 in normal day visibility and only stopped when instructed to do so by ATC. A Boeing 737-700 being operated by Westjet as WJA318, which had been on short final to land on the same runway and had already received landing clearance, was instructed to go around.

Investigation

An Investigation was carried out by the Canadian TSB. The event was not notified to the Board until the following day and the DHC8-400 CVR data relevant to the incident were found to have been overwritten. Data from the FDRs removed from both aircraft were downloaded but only the 737 data was of sufficient positional accuracy to be of any use. The TWR ASDE recording was available. The runway holding point did not have a lit stop bar.
