NTSB investigates controller as part broader investigation of LaGuardia Airport collision

Investigators are looking into the fatal collision between an 'Air Canada Express jet and a firetruck at New York LaGuardia Airport. They want to speak to an air traffic controller who was dealing with another emergency just before the crash.

The Chair of the National Transportation Safety Board, Jennifer Homendy, told reporters at LaGuardia airport that the controller will be part of an investigation by this independent federal agency which "will rule nothing out."

Air traffic control staffing is a concern at U.S. major airports, following the accident that killed two pilots while seriously injuring nine others.

Homendy stated that the collision occurred shortly before midnight Sunday during a controller's overnight shift. Normally, the controller would be relieved of duty following such an incident.

She said, "It was a pretty traumatizing experience for the air traffic controller." "We will want to interview the air traffic controller and others who were in that tower."

U.S. experts in air safety said that the investigation would focus on the communications between the plane landing and the controller, as well as the trucks.

The U.S. Federal Aviation Administration reported 80 runway incursions in the quarter ending December 31. This is up from 54 during the same period last year.

The NTSB has recovered the flight data recorder and cockpit voice recorder to be analyzed.

Prior Emergency

The air traffic controllers decide when aircraft can land, take off and when vehicles on the ground can enter the runway. According to a recording on liveatc.net, the controller who called for Air Canada Flight 8646 land was trying to locate a gate for United Airlines flight 8786 that had complained about a "bad smell".

United pilots declared an emergency and decided to not fly due to the smell that made flight attendants sick.

As the Air Canada Express CRJ-900 operated by regional partner Jazz Aviation landed, the fire trucks that appeared to have cleared the same controller for crossing Runway 4 were heading to the United flight.

The controller said "Stop truck one, Stop" shortly after authorizing passage across the runway. The plane hit the firetruck as it arrived.

According to a separate audio uploaded by liveatc.net an unidentified controller, who appears 'to be the one responsible for the crash,' told another pilot that he was dealing with an earlier emergency, after the collision.

He said, "I'm sorry," in a trembling voice.

The pilot who had witnessed the crash responded, "Nah, man, you did the best you could." The pilot said that the previous incident "wasn’t good to see."

STAFFING LEVELS

At LaGuardia, as well as other major airports, air traffic controllers are often responsible for multiple flights. Four commercial?pilots said it wasn't uncommon to have a single controller handling both the tower and ground, which are two different roles in air traffic control.

"The real question is, 'What is the sleep and work schedule of this controller and is fatigue a problem?' John Cox, a pilot and aviation safety expert from the United States, said:

Homendy stated that it was premature to discuss staffing.

Sean Duffy, the U.S. Secretary of Transportation, dismissed any concerns about understaffing.

Duffy said to reporters in LaGuardia, on Monday, that the airport has 33 air traffic control officers at an airport that is aiming for 37. Duffy denied reports that the controller worked alone on Sunday night.

Flightradar24 flight records show that 51 flights landed at LaGuardia in the hour prior to the Air Canada Express crash. This is more than double the 23 scheduled flights during the hour when the crash occurred. The cause of the jump is not known.
