An NYC helicopter that crashed and killed 6 last year shows signs of bird strike, safety board says

Remains of several geese were found on the helicopter’s rotors and left horizontal stabilizer. One witness told the NTSB that just minutes before the crash a large flock of geese took flight in the area.

“The geese were big and there were many of them. When the helicopter went bang, I immediately thought it was a bird strike,” the witness told NTSB investigators.

The Smithsonian Institution’s Feather Identification Lab identified remains from different breeds of geese on the wreckage. Some of those birds average about three pounds. The remains also include female Canada Geese, which can average nearly eight pounds.

The NTSB has investigated 24 helicopter bird strike crashes in the past 25 years, including three fatal ones. Helicopter pilots are encouraged to try to avoid areas where birds are known to be present and fly slower to minimize the potential damage from an impact.

“Bird strikes continue to be a hazard in aviation and one that can be difficult to mitigate,” said aviation safety expert Jeff Guzzetti, who used to investigate crashes for both the NTSB and Federal Aviation Administration.

The “ miracle on the Hudson” highlighted the danger of bird strikes when a US Airways jet hit a flock of birds and lost power in both engines shortly after takeoff in 2009. Pilot Chesley “Sully” Sullenberger was hailed as a hero after he landed the powerless plane in the Hudson River and all 155 people on board were rescued.

In last year’s crash, witnesses described seeing the helicopter’s tail and main rotor breaking away and smoke pouring from the spinning chopper before it slammed into the water.

The helicopter took off from a downtown heliport that afternoon and flew north along the Manhattan skyline before heading south toward the Statue of Liberty. Less than 18 minutes into the flight, parts of the aircraft were seen tumbling into the water.

Rescue boats circled the submerged aircraft within minutes of impact and recovered the bodies from the water. Later recovery crews hoisted the mangled Bell 206L-4 helicopter out of the river for investigators to examine.

New York Helicopter Tours shut down after the crash, and the FAA issued an emergency order to ground all the company’s flights after learning it had fired its operations director minutes after he had agreed to suspend flights during the investigation.

The FAA said at the time that it suspected the firing was retaliation for a safety decision.

The company’s director of operations, Jason Costello, agreed to voluntarily halt flights while the crash was being investigated. But 16 minutes after Costello sent an email to the FAA, the company’s chief executive officer sent a separate email to the agency saying he did not authorize the halt and that Costello was no longer an employee.
