Hualapai Nation Police Chief Francis Bradley said six passengers and a pilot were on board the Papillion helicopter when it crashed around 5:20 p.m. The other four were injured, and were still being treated at the scene.
An after-hours phone call to aerial tour company Papillion was not immediately returned Saturday. The company’s website says it flies roughly 600,000 passengers a year on Grand Canyon and other tours.
Federal Aviation Administration spokesman Allen Kenitzer said the Eurocopter EC130 crashed in unknown circumstances and sustained heavy damage.
Federal authorities will investigate.
