BOISE, Idaho — The National Transportation Safety Board says an August 2010 helicopter crash that killed two Idaho Fish and Game biologists and the pilot was caused when a metal clipboard belonging to one of the biologists hit the tail rotor.
The report released Thursday says it’s unclear if the clipboard fell out of an external luggage rack or came from inside the three-seat helicopter. The helicopter had a fully-enclosed cabin, but officials say doors are sometimes opened in flight.
Killed were 47-year-old Larry Barrett and 34-year-old Danielle Schiff, who were to count salmon spawning nests in the Selway River. The pilot was 43-year-old Perry J. Krinitt of Belgrade, Mont.
The debris path included parts from the tail rotor and clipboard leading to the crash site in the town of Kamiah.
