NTSB narrative
Prior to departure, the commercial pilot attempted to remove ice and snow contamination from the wings of the float-equipped airplane, but some contamination remained. During the takeoff run, the airplane failed to become airborne before reaching the end of the lake. The airplane slid along a gravel spillway for several hundred feet before nosing over. The airplane sustained substantial damage to the wings, empennage, and fuselage. The pilot stated that there were no preaccident anomalies with the airplane that would have precluded normal operation. The pilot noted that the accident might have been avoided if he had removed all the frozen contamination from the wing or waited for above-freezing temperatures.
Probable cause
The pilot's decision to take off with ice- and snow-contaminated wings.

- 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 2012-10-01.
