NTSB: runway safety system was not active before fatal Air Canada Express crash

The National Transportation Safety Board reported Thursday that a critical?runway safety?system failed to activate prior to a fatal?collision on March 22 between an Air Canada Express jet and a fire?truck, which killed two pilots. In its preliminary report, the NTSB said that the red runway entry lights that warn of unsafe crossings were still on three seconds prior to the collision. The NTSB stated that the system is designed to turn off the lights about 2 to 3 second before the plane reaches each intersection.

The Express CRJ-900 regional plane touched down about 2 seconds before it collided and was traveling at 104 mph when the accident occurred.

The NTSB is in charge of the investigation into the fatal crash of a CRJ900 jet operated by Air Canada regional partner Jazz Aviation. The crash sent 39 passengers and crew members to the hospital, six of whom suffered serious injuries. The ground surveillance system at the airport did not send out an alert to warn of any vehicles near the runway. And the fire truck which collided with a jet was missing a transponder, which would have sent its location to air traffic control.

NTSB: The truck driver who was involved in the accident recalled hearing "stop stop halt" on the tower frequency radio. He did not realize that it was for his vehicle. However, when he heard "Truck 1 "stop stop halt", he realized that this was the transmission for them and noticed that their vehicle had entered the runway. The NTSB stated that the local controller, who was handling the Air Canada plane, had 18 years' experience. The ground controller was the controller-in charge and had 19 years' experience.

The Federal Aviation Administration encourages airports to equip their fire trucks with transponders, as it makes tracking the vehicles easier at busy airports. (Reporting and editing by Stephen Coates; David Shepardson)
