NTSB narrative

The airplane was destroyed while maneuvering at low altitude when it impacted an ice covered lake in a steep nose down attitude. One witness reported that he observed the pilot preflight and start the airplane. He reported that the airplane sounded "okay" during taxi and takeoff. Witnesses to the accident reported seeing the airplane flying low over the lake. One witness stated the airplane's altitude was between 60 - 100 feet above ground level (agl). The witnesses reported seeing the airplane enter a steep climb to about 300 feet agl. Then the airplane reversed direction and entered a steep descent and impacted the ice. One witness reported the airplane "went straight up in the air about 200 feet, made a hairpin turn, and came straight down, hitting the ice nose first." The engine, landing gear, and cockpit of the cabin broke through the ice and remained submerged. The wings and the rest of the fuselage were intact and remained on top of the ice. The post accident inspection of the airplane revealed no preexisting anomalies that could be associated with a pre-impact condition. One witness reported that it was common for the pilot to do low passes and maneuver at low altitude. Another witness reported that it was not uncommon for the pilot to perform "crop duster turns" at low altitudes.

Probable cause

The pilot's inadequate decision to conduct a low altitude flight maneuver without sufficient altitude to maintain clearance from the terrain. Low altitude flight and ostentatious display are contributing factors.

  • 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: investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
