The National Transportation Safety Board (NTSB) released a preliminary report detailing multiple safety failures that led to the deadly crash at New York's LaGuardia Airport last month. The collision involved an Air Canada Express plane and a firetruck, resulting in the deaths of two pilots—Antoine Forest and Mackenzie Gunther—and injuries to dozens of others.
Key Takeaways
The NTSB released a preliminary report on the deadly LaGuardia Airport collision between an Air Canada Express plane and a firefighting vehicle, identifying multiple safety failures. The firetruck lacked a transponder, causing the ASDE-X system to fail in predicting the conflict with the landing airplane.
The NTSB found that the firetruck was not equipped with a transponder, which would have triggered alerts from the airport's automatic surface detection system (ASDE-X). This system failed to uniquely identify each of the seven responding vehicles or reliably determine their positions. As a result, it did not predict a potential conflict with the landing airplane.
The report also highlighted confusion over radio communications. The turret operator in Truck 1 recalled hearing the words 'stop stop stop' but did not know who the transmission was intended for. He subsequently realized it was meant for them and noticed that they had entered the runway, seeing the airplane's lights just before the collision.
The runway entrance lights (RELs), designed to warn vehicles not to cross when an aircraft is approaching, were illuminated but extinguished about three seconds prior to the collision. The report does not indicate whether the truck crew saw or reacted to these warning lights.
The NTSB report provides a detailed timeline of events leading up to the crash. At 11:35 p.m., an air traffic controller cleared Air Canada Express Flight 8646 to land on runway four, while simultaneously giving permission for emergency vehicles to cross the same runway. The firetruck and six other vehicles were responding to an emergency at LaGuardia's Terminal B.
The report reveals that one of the emergency vehicles attempted to contact the tower but their radio transmission was 'obscured' by a simultaneous message on that same frequency. The NTSB did not specify whether they interviewed the firefighter driving the truck or either of the two controllers in the tower that night. The investigation is ongoing, and both the FAA and Port Authority are reviewing the findings to ensure safety protocols are strengthened.
