WASHINGTON - A firefighting helicopter crash that killed nine people two years ago was caused by deceptions on the part of the company that leased the aircraft to the U.S. Forest Service and a lack of federal safety oversight, the National Transportation Safety Board determined Tuesday.
Carson Helicopters of Grants Pass, Ore., intentionally altered documents to exaggerate the helicopter's performance capabilities in order to win a Forest Service contract, the board said.
But the Federal Aviation Administration and the Forest Service missed several opportunities to uncover those problems, the board said.
