CRJ2 / B773, Toronto Canada, 2019

CRJ2 / B773, Toronto Canada, 2019

Summary

On 9 August 2019, a Bombardier CRJ-200LR about to depart Toronto which had read back and actioned a clearance to line up on the departure runway then began its takeoff without clearance and only commenced a high speed rejected takeoff when a Boeing 777-300 came into view crossing the runway ahead. A high speed rejected takeoff was completed from a maximum speed of around 100 knots. The Investigation concluded that an increased crew workload, an expectation that a takeoff clearance would be received without delay and misinterpretation of the line up instructions led to the premature initiation of a takeoff.

Description

On 9 August 2019, a Bombardier CRJ-200LR, (C-GKEJ) being operated by Air Georgian on a scheduled international passenger flight from Toronto to Ohio as CGN7339 commenced takeoff on runway 33R as a Boeing 777-300 (C-FIUR) being operated by Air Canada on a scheduled international passenger flight from Copenhagen to Toronto as ACA883 was crossing the runway at an intermediate intersection after landing in normal day visibility. On seeing the 777 ahead, the CRJ carried out a high speed rejected takeoff and were able to clear the runway well before reaching the intersection at which the 777 was crossing.

Investigation

An Investigation was carried out by the Canadian Transportation Safety Board. It was not able to use relevant data from either the CVR or DFDR of the CRJ200 because the subsequently flown 1 hour flight resulted in the overwriting of the event on 30 minute CVR and the operator failed to secure the DFDR as required under applicable regulations. The Investigation was therefore reliant primarily on recorded ATC data.
