On 28 January 2019, a departing Embraer 170-200 narrowly avoided collision with part of a convoy of four snow clearance vehicles which failed to follow their clearance to enter a parallel taxiway and instead entered a Rapid Exit Taxiway and continued across the runway holding point before stopping just clear of the actual runway after multiple calls to do so. A high speed rejected takeoff led to the aircraft stopping just before the intersection where the incursion had occurred. The Investigation noted the prevailing adverse weather without attributing any specific cause to the vehicle convoy’s failure to proceed as cleared.
Description
On 28 January 2019, an Embraer 170-200 (C-FEJB) being operated by Sky Regional Airlines on a scheduled international passenger flight from Toronto to Dallas Fort Worth as SKV7665 had been cleared to take off on runway 06L in normal day IMC when a convoy of snow clearance vehicles got lost and crossed a holding point for the same runway. The aircraft was instructed to reject takeoff having reached approximately 110 knots and stopped 60 metres from the lead vehicle which itself had stopped just clear of the actual runway after multiple ATC calls to do so following activation of an automatic incursion alert.
Investigation
An Investigation was carried out by the Canadian Transportation Safety Board (TSB) using data downloaded from the CVR and FDR of the aircraft involved and recorded ATC voice and radar data.
