Unstabilized approach leads to June 2011 runway excursion at Toronto/Buttonville Airport

Gatineau, Quebec, 03 October 2012 – The Transportation Safety Board of Canada (TSB) today released its investigation report (A11O0098) into the runway excursion involving a Dassault Falcon 10 business jet operated by Skycharter Ltd. that occurred at the Toronto/Buttonville Municipal Airport on 17 June 2011.

"Unstabilized approaches and excessive airspeed have been causal factors in many approach and landing accidents over the years," said Don Enns, Manager, Air Investigation Operations, Ontario Region. "Flying fast and high on approach can result in aircraft control difficulties, leading to runway excursions."

While preparing to land at the Toronto/Buttonville Municipal Airport, the captain and first officer were flying an unstablilized approach with excessive airspeed. The aircraft overshot the runway centreline while turning onto the final approach course for Runway 33. The pilot tried to regain the runway centreline with a sharp turn to the left. Shortly after, the ground proximity warning system gave a warning to pull up, and the first officer called for a missed approach. The captain continued with the approach. Immediately after landing, the aircraft departed the runway surface to the right, where it traversed the grass infield onto the adjacent taxiway. The aircraft came to a stop before Runway 21/03. There were no injuries to either crew member, and the aircraft was substantially damaged.

The investigation also found that the crew did not fully adhere to the company's standard operating procedures after take-off. It also found that numerous checklist items were not completed and non-standard wording was used while carrying out procedures. These factors were found to have contributed to the accident.
