NTSB narrative

The non-instrument-rated private pilot departed on a multi-leg cross-country trip without obtaining a weather briefing or filing a flight plan. Prior to the flight, the pilot asked a friend, a commercial helicopter operator, to accompany him on the trip, as the pilot had never flown over mountainous terrain. The friend could not accompany him due to a prior commitment and tried to dissuade the pilot from going because he thought the pilot needed mountain flying experience, but the pilot insisted on making the flight. When the helicopter failed to arrive at its destination, an alert notice was issued. The helicopter was located by aerial search in mountainous terrain 4 days after the accident. Examination of satellite images revealed that the wreckage was located in a box canyon and that the wreckage path was oriented opposite the intended route of flight. An AIRMET advisory for instrument meteorological conditions and mountain obscuration were current for the route of flight and the crash site. Satellite images from over the accident site around the time of the accident depicted an area of low stratiform clouds that extended over the area. Examination of the wreckage revealed no evidence of pre-impact mechanical malfunction, and the damage was consistent with controlled flight into terrain. Post mortem examinations and testing revealed heart disease and the use of amphetamine and anti-depressant medications. At least two of the medications that the pilot was taking are not permitted by the Federal Aviation Administration for use while flying, but he did not report them. However, it could not be determined whether the pilot's heart disease or his use of unapproved medications posed a significant risk to flight safety.
