Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The certificated commercial pilot, with three passengers aboard, departed on a cross-country personal flight through mountainous terrain, in a float-equipped airplane. The purpose of the flight was to show the three passengers some Alaskan scenery. The route of flight included a stop at a remote lake, frequently visited by the pilot. About 6 hours after departure, an ELT signal was received, and an aerial search was initiated. The wreckage was located in an area of mountainous terrain, and along the airplane's anticipated return flight route, between the remote lake and the airplane's home base airport. A State of Alaska, Fish and Wildlife Protection Officer involved in the search, reported that after locating the wreckage, he landed his wheel-equipped airplane along a ridgeline, located about 1,000 feet above the wreckage site. During the approach for landing, he encountered winds out of the southeast, estimated to be 17 to 20 knots. He added that the location of the accident airplane's wreckage was situated on the downwind side of the mountainous terrain. Postaccident investigation revealed that the nose of the airplane impacted in a near vertical attitude, on the soft, tundra-covered terrain. No mechanical anomalies were noted with the airframe or engine.
NTSB Probable Cause Narrative
The pilot's inadvertent stall of the airplane during an unknown phase of flight.
