During a water takeoff on a canal with a left bend, a floatplane pilot observed a 15-20 ft piling and a peninsula. After steering right of the piling, the rear of the floats contacted the ground during rotation, causing the aircraft to flip inverted.

Incident Summary

A pilot reported an accident during a water takeoff from a canal. The canal featured a left bend, and the pilot initiated the takeoff run along its length.

Sequence of Events

As the aircraft rounded the bend, the pilot saw a 15-20 foot high piling (post) positioned in the middle of the canal. Approximately 300 yards beyond the piling, a peninsula of land extended into the waterway. The pilot steered the aircraft to the right of the piling and continued the takeoff run. Within 50 feet of the peninsula, the pilot rotated the aircraft for takeoff. The nose lifted, but the rear end of the aircraft's floats contacted the ground. This contact pitched the nose downward, and the aircraft subsequently flipped inverted and came to a stop.
