What happened
The pilot was attempting a takeoff to the east from a remote lake using a float-equipped airplane. Conditions were challenging, with the pilot estimating prevailing easterly winds at 35 knots and gusts reaching up to 55 knots. Shortly after applying power during the initial takeoff roll, a sudden gust of wind lifted the right wing. This unexpected lift caused the airplane to roll over to the left side.
The investigation
The investigation focused on the immediate circumstances of the accident. The pilot's report indicated that the rollover was triggered by a specific wind gust during the critical takeoff phase. No mechanical failures were reported prior to the event.
