NTSB: Chopper that crashed into NY river too heavy
Saturday, December 22, 2012
NEW YORK (AP) — A helicopter that crashed into the East River during a sightseeing tour last fall, killing three people taking part in a birthday celebration, was carrying too much weight, according to a federal report released Thursday.
The National Transportation Safety Board report doesn’t conclude what caused the crash, which occurred near the United Nations headquarters; a determination is expected in about two months.
But the report said the Bell 206 chopper had a capacity of 3,200 pounds. The estimated weight at takeoff, including all five passengers and fuel, was 3,228 pounds, the report said.
Federal investigators also weighed the helicopter after it was pulled from the river and estimated it could have been as heavy as 3,461 pounds, but that figure included soggy cushions and other water trapped in the aircraft after it was raised.
Pilot Paul Dudley, the manager of an airport in Linden, N.J., reported that he asked people for their weights and calculated that they would not be too heavy, according to the NTSB report, but the surviving passenger said the pilot didn’t ask and didn’t calculate the total weight.
A lawyer for Dudley noted Thursday that the report also discusses a potential aerodynamic problem unrelated to the weight.
Dudley, 56, told the NTSB that the nose of the helicopter swung unexpectedly to the left as he was taking off. When he tried to turn right, the aircraft suddenly went out of control and hit the river, which separates Manhattan from Brooklyn and Queens. The report noted that the Federal Aviation Administration issued an advisory years ago warning that helicopters flying at low speeds can experience a problem like the one he described, known as an “unanticipated yaw.”
“The key word being ‘unanticipated,’” attorney Robert Hantman said in a statement. He said the crash “principally resulted from the helicopter having a propensity” for the problem.
“Mr. Dudley, who had an unblemished 28-year aviation record, is still recovering and mourns the loss of his friends every day,” Hantman added.
The helicopter sputtered and crashed shortly after takeoff from a riverbank heliport on Oct. 5, 2011. It sank 35 feet below the surface of the slow-moving water off 34th Street in midtown Manhattan, a few blocks south of the U.N. headquarters.
The sightseeing tour was part of a birthday celebration. The passengers were friends of the pilot’s family: Paul and Harriet Nicholson, a British couple who were living in Portugal; the wife’s daughter, Sonia Marra, also British, and the daughter’s partner, Helen Tamaki, a citizen of New Zealand. The daughter and her partner were living in Sydney.
Marra died at the scene; her body was pulled from the wreckage. Harriet Nicholson and Tamaki died later.
Paul Nicholson survived.
He told federal investigators that the chopper’s nose was pointed down at takeoff and he was leaning forward in his seat against the restraint. By his account, “the helicopter then began moving ‘erratically,’ the pilot made an exclamation similar to ‘oops’ and the passenger then ‘knew something wasn’t quite right,”’ according to the report.
The helicopter had been inspected two days before the crash and had no problems. An examination after it was pulled from the water showed no major engine malfunctions. A drug and alcohol test for Dudley came back negative.
Dudley has more than 2,287 hours of flight experience. On April 21, 2011, he failed part of his commercial pilot certificate test, but he was re-examined on takeoff, landing and go-arounds three days later and passed, according to the report.
