Air Canada Express flight 8615, a DHC-8-311, collided with a fuel truck while taxiing to gate at Toronto Pearson Airport in Canada. Five persons were injured in the accident. Flight 8615 departed Toronto on May 9, 23:03 hours local time, on a domestic flight to Sudbury. Visibility at Sudbury was poor and the flight was not able to land. The flight crew elected to return to Toronto, where a normal landing was made at 01:25 hours local time (May 10). As the aircraft was taxiing to the gate, a collision occurred with a fuel truck. The aircraft spun and sustained serious damage to the left side of the flight deck. The left hand rear cargo door was pushed inward and the no.1 propeller also suffered damage. Findings as to causes and contributing factors: 1. The limited field of view to the right of the fuel tanker driver’s cab caused by the front elevating service platform and its structural elements, along with the condensation on the windows, resulted in the driver being unable to see the aircraft in time to avoid the collision. 2. The captain had a clear field of view in the direction of the oncoming fuel tanker but the visibility was limited due to darkness, rain, and reflected light, and he did not see the oncoming tanker during the critical moments before the collision.
