On 30 January 2016, an Embraer 190-100 crew lined up on their assigned departure runway in good visibility at night without clearance to do so just as an Airbus A320 was about to land on it. The Investigation attributed the incursion to crew error arising from misinterpretation by both pilots of a non-standard Ground Controller instruction to position alongside another aircraft also awaiting departure at the hold when routinely transferring them to Tower as an instruction to line up on the runway. The failure to use the available stop bar system as a basis for controller incursion alerting was identified.
Description
On 30 January 2016, an Embraer 190-100 (C-FNAW) being operated by Air Canada on a scheduled passenger flight from Toronto to New York La Guardia as ACA 726 entered runway 24R at night in normal ground visibility at the same time as an Airbus A320 (C-FZQS) being operated by Air Canada on a scheduled passenger flight from Puerto Vallarta, Mexico to Toronto as ACA 1259 was about to land on it. The A320 crew advised ATC of this at 270 feet agl and initiated a go around. The Embraer 190 was subsequently cleared to take off and the A320 subsequently landed on its second approach.
Investigation
An Investigation was carried out by the Canadian Transportation Safety Board (TSB). Sufficient relevant recorded data and testimony was available to enable a detailed reconstruction of the events leading up to the incursion. It was noted that the prevailing weather conditions had been benign and had played no part in the incursion.
