NTSB narrative
THE PILOT WAS TAKING OFF FROM AN AIRSTRIP TO POSITION HIS FLOATPLANE AT A SEAPLANE BASE. THE AIRPLANE WAS EQUIPPED WITH A PORTABLE SIX WHEEL ' DOLLY ' WHICH ATTACHES TO THE FLOATS, AND AUTOMATICALLY DETACHES WHEN THE AIRPLANE BECOMES AIRBORNE DURING TAKEOFF. ACCORDING TO THE FAA, THIS WAS THE PILOT'S FIRST FLIGHT WITH THIS LOCALLY FABRICATED ARRANGEMENT. THE PILOT STATED THAT DURING TAKEOFF THE ' DOLLY ' MALFUNCTIONED, AND THE AIRPLANE TURNED APPROXIMATELY 70 DEGREES TO THE LEFT REDUCING THE SPEED OF THE AIRPLANE. THE AIRPLANE SETTLED BACK ONTO THE RUNWAY SIDEWAYS BREAKING OFF THE' X BRACE RESULTING IN THE FLOAT STRUCTURE COLLAPSING UNDER THE AIRPLANE.' THE RIGHT WING THEN STRUCK THE GROUND, BREAKING THE SPARS. THE PILOT REPORTED THAT THERE WAS 5 KNOTS RIGHT CROSSWIND. A WITNESS REPORTED THAT DURING TAKEOFF ROLL THE RIGHT WING LIFTED, FOLLOWED BY THE SEPARATION OF THE RIGHT FLOAT DOLLY. THE AIRPLANE THEN SWERVED LEFT ON THE LEFT FLOAT DOLLY AND THE LEFT WING STRUCK THE GROUND. THE WITNESS SAID THE AIRPLANE SLID SIDEWAYS, COLLAPSING THE FLOATS.
Probable cause
THE PILOT INADEQUATE COMPENSATION FOR WIND WHICH RESULTED IN THE LOSS OF DIRECTIONAL CONTROL.

- 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. 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.
