The Transportation Safety Board of Canada is investigating a runway overrun by a Sky Lease Cargo Boeing 747-400 Freighter at Halifax Stanfield International Airport.
At 05.05 local time on 7 November, the aircraft coming from Chicago O’Hare International Airport overran Runway 14 coming to a rest 210 metres off the end of the runway.
There were four crewmembers and no cargo on board the aircraft, which struck a localiser antenna during the overrun.
The aircraft suffered from a collapsed landing gear, two engines were separated and the remaining two were substantially damaged, and there was a small post-impact fire from the detached number two engine, which was lodged under the tail.
So far, the TSB has sent the flight data recorder, cockpit voice recorder and other systems with flight data to its Engineering Laboratory in Ottawa for analysis.
An initial examination of the accident site has been carried out along with a thorough examination of Runway 14/32.
The investigation team is in contact with Sky Lease, the US National Transportation Safety Board, the US Federal Aviation Administration, Boeing, Pratt & Whitney, Halifax Airport Authority, NAV Canada and Transport Canada.
Transport Canada has appointed a Minister’s Observer to obtain factual information and advise of any regulatory factors, and identify deficiencies requiring corrective action.
The TSB says investigators will analyse cockpit voice and flight data recorders, conduct interviews with witnesses and other parties who can provide information, review audio and radar data from NAV Canada, analyse weather and runway information, examine aircraft systems, maintenance and other records, review policies and procedures, and examine the terrain at the end of the runway to determine what role it played in aircraft damage.
