HALIFAX -- The Transportation Safety Board of Canada says it has finished its examination of the site where an Air Canada plane crashed this weekend in Halifax.

The safety board says on its Twitter account that it expects the aircraft to be removed from the runway in the next couple of days.

Investigators are trying to determine what caused flight AC624 to touch down 335 metres short of the runway at the Halifax airport early Sunday morning.

The plane also skidded along the runway for another 335 metres before coming to a stop.

All 133 passengers and five crew on board the Airbus A320 survived the crash, although 25 people were sent to hospital.

Air Canada says one of the pilots underwent minor surgery and one passenger was still in hospital.
