The pilot's family has been informed, CNN quoted a source as saying. Authorities also ruled out a connection of a terror angle with the crash.
The Agusta A109E helicopter took off from the 34th heliport at around 1:32 pm (local time) and crash-landed on the roof of the 54-storey building at 787 Seventh Avenue after being airborne for 11 minutes, police said.
De Blasio remarked that "there was no indication that the crash was an act of terror" while Cuomo said that people who were in the building said they felt the "building shake."
"FDNY members made their way to the roof and we were able to put water on the fire quickly. The fire has been extinguished, and the fuel leak has been mitigated," FDNY Commissioner Daniel A. Nigro told reporters.
The helicopter flew around Battery Park on the southern tip of Manhattan and up the west side of the island, police said.
Large portions of midtown Manhattan streets were closed to pedestrian and vehicle traffic, as the police initiated an investigation in the area.
The area covers 15 city blocks and two avenues and also includes New York's iconic Times Square and many Broadway theatres.
