NTSB Investigators Arrive in Kauai

PRINCEVILLE, KAUAI (KHNL) - Federal investigators arrived today to investigate the cause of a deadly tour helicopter crash on Kauai. Thursday's crash at Princeville Airport claimed the lives of the pilot and three passengers. Three other passengers are in critical condition at the Queen's Medical Center. NTSB safety investigator Brian Ravner explains how the process works. "We divide these investigations into 3 parts: the man, machine, and environment."

They plan to interview several eyewitnesses who saw the bird crash nose first. Rayner previews what one eyewitness will say. "She said she watched the end of the accident flight and watched the helicopter touch the ground."

Sunday, they plan to move the chopper. "We've schedule removal of the wreckage tomorrow morning to a remote site for a detailed exam," says Rayner.

Also the chopper company Heli USA issues a statement about the crash. John Powell told the media, "We'd like to extend our condolences and prayers for the family members and the passengers and pilot involved in this accident." It has ceased flights in Princeville until Monday. The NTSB hopes to release its preliminary report in 2 weeks.
