The rules governing air traffic over New York’s Hudson River need to be rewritten to prevent another mishap like this month’s fatal collision of a small plane and a sightseeing helicopter, federal safety investigators said Thursday.
The wreckage of a plane that collided with a helicopter is lifted this month from the Hudson River.
The recommendation comes three weeks after nine people were killed when the two aircraft collided in the congested airspace bordering Manhattan.
The recommendation is noteworthy both because of its sweeping nature and its timing. Ordinarily, the National Transportation Safety Board makes recommendations at the conclusion of its investigation, which typically take a year.
But in a letter to FAA Administrator Randy Babbitt, NTSB Chairman Deborah Hersman said that based on preliminary findings, the safety board is concerned about the “safety of flight” over the Hudson River. She outlined a series of changes, among them requiring that helicopters and fixed-wing aircraft fly at different altitudes over the river.
She also pointedly said board is concerned about “the performance of air traffic controllers” at Teterboro Airport in New Jersey, who were monitoring the plane’s flight during the August 8 collision.
“The NTSB is concerned with the complacency and inattention to duty evidenced by the actions of the [Teterboro] controller and the supervisor during the events surrounding this accident,” Hersman wrote.
She added the controller made a personal phone call about two minutes after clearing the plane for takeoff and “was not fully engaged in his duties” at the time of the accident, while the supervisor had left the building on a personal errand without telling the controller.
All six people aboard the helicopter and all three occupants of the plane died in the collision, which was witnessed by numerous people on the ground.

Representatives of the air traffic controllers did not immediately respond to Thursday’s NTSB report. But previously, they have said it is wrong to place blame for the collision on the controller, saying the helicopter did not appear on his radar screen until after he had handed off monitoring of the plane to another tower.
Both aircraft were operating under visual flight rules, which place responsibility in the pilots’ hands to “see and be seen.”
The collision happened in the “Hudson River class B exclusion area,” a passageway that allows aircraft to fly north and south along the Hudson River without authorization from air traffic controllers who control traffic in the class B airspace surrounding New York’s major airports.
The NTSB said aircraft departing Teterboro can use the Hudson River exclusion area, but are required to remain at or below 1,100 feet.
“The FAA has established procedures for operation within the Hudson River class B exclusion area that are designed to minimize the risk of collision, but as this accident demonstrates, there are still situations when these established procedures are not enough,” Hersman said.
The recommendations ask the FAA to establish a special flight rules area (SFRA) for the class B exclusion areas near New York City; require vertical separation between helicopters and airplanes in these areas; require pilots to complete specific training on the SFRA requirements before flight within the area; and conduct a review of other airspace configurations where specific pilot training and familiarization would improve safety
