NTSB narrative
The noninstrument-rated pilot and one passenger were flying as part of a group of three airplanes on a sightseeing tour. The accident airplane and one of the other airplanes in the group encountered deteriorating weather and made an unplanned stop at an airport along their route of flight. After receiving fuel and updated enroute weather, both pilots decided to depart for their original destination.
During the second attempt to fly to the destination airport, the two airplanes again encountered deteriorating weather conditions. The pilot of the accident airplane decided to maintain visual flight rules, and the pilot of the other airplane requested an instrument flight rules clearance to the destination airport. A short time later, the pilot of the accident airplane contacted air traffic control and stated that he was having difficulty maintaining visual conditions and subsequently requested an instrument clearance. The pilot reported climbing through 6,800 feet for 7,000 feet, then no further communications were received. The wreckage was located on a brush- and tundra-covered hillside; the left wing had separated from the airplane inflight, followed by the separation of other airplane components before impact.
Given the reported weather, the pilot's lack of an instrument rating, his request for an instrument clearance, the wreckage path, and the lack of any mechanical anomalies, it is likely that the pilot encountered instrument meteorological conditions and became spatially disoriented while attempting to climb to a higher altitude. It is also likely that the pilot then lost control of the airplane, and entered a steep spiraling dive from which he was unable to recover. During the dive, the aerodynamic forces increased to the point that the left wing separated from the airplane, which tightened the spiral, and led to the in-flight structural failure of other sections of the airplane.
Probable cause
The noninstrument-rated pilot's decision to continue visual flight into instrument meteorological conditions likely leading to spatial disorientation, which resulted in a loss of airplane control and in-flight structural failure.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-07-19.
