PRINCEVILLE, HAWAII — A tour helicopter crashed at an airport on the island of Kauai on Thursday, killing four people, including the pilot, and critically injuring three, officials said.

The crash occurred at Princeville Airport in midafternoon, shortly after a Heli-USA Airways helicopter pilot radioed that he was having hydraulic problems, according to a statement from Kauai Fire Chief Robert Westerman.

Nigel Turner, chief executive of Las Vegas-based Heli-USA, said the aircraft was at the end of its tour and minutes from its scheduled landing when it crashed.
