It remained unclear why the Eurocopter EC130 aircraft, a Federal Aviation Administration (FAA) official said, adding that the helicopter was heavily damaged.
The helicopter was on a tour of the canyon and more than a mile deep as it went, Reuters reported, citing information from KNXV-TV.
After an hour of calling to aerial tour company Papillion was not immediately returned on Saturday.
The website of the company says it will fly about 600,000 passengers a year on journeys of the Grand Canyon and other sites.
The FAA and the National Transportation Safety Board will investigate.
