Authorities investigate deadly helicopter crash-landing on New York City skyscraper

Update 2:45 p.m. EDT June 11: Investigators on Tuesday sifted through the scattered, scorched remains of a helicopter after its pilot crash-landed Monday on the top of a Manhattan high-rise.

Authorities said the pilot, who was identified by officials in New Jersey as Tim McCormack, originally left New Jersey with a passenger around 11:30 a.m. He dropped off the passenger in New York City and stayed until around 1:30 p.m. before departing for Linden, New Jersey, NTSB air safety investigator Doug Brazy said Tuesday at a news conference.

It was not immediately clear why the pilot stayed in the city. Brazy said investigators have determined he reviewed weather reports during that time. Authorities believe the rainy  weather Monday might have contributed to the crash.

“That’s something we’re looking into,” Brazy said. “We have much more work to do before this investigation is complete.”

Authorities are also delving into whether McCormack tried to send a radio transmission around the time of the crash and whether his flight path was meant to bring him into Midtown Manhattan.

“As far as we know the pilot was not in communication with (air traffic control), nor was he required to (be),” Brazy said. “He may have ventured into airspace requiring that he contact air traffic control (during the crash).”

Investigations like the one launched Monday typically take between 18 and 24 months, Brazy said.

Authorities continue to investigate.

Update 8:50 pm EDT June 10: The pilot, who was the only one killed  in the crash, was identified as Tim McCormack, 58, a former fire chief in upstate New York and a veteran pilot, according to The Associated Press.

The crash occurred 11 minutes after take-off from a heliport along the East River and about a mile away, the AP reported.

McCormack was described as “a highly seasoned” and “well-regarded” pilot by the director of the Linden Municipal Airport, who also speculated that either the weather or a mechanical issue most likely cuased the crash.

People inside the building said they felt it tremble and smelled smoke in the stairwells as they were being evacuated.

Investigators are trying to figure out why the pilot decided to take off in such bad weather. It was raining with overcast skies at the time of the crash.

Firefighters were able to quickly douse the flames from the crash and mitigate the fuel spill.
