Analysis

The float plane crashed shortly after taking off from Lake Delton while of a sight-seeing flt. The acft was used daily during the tourist season on flts of aprx 15 min long. This was the 8th or 9th flt of the day & was the 4th or 5th flt since refueling. A passenger & svrl witnesses on the ground thought that the eng had lost power. A post crash exam of the eng did not reveal any specific reason for the loss of power. The survivors of the crash both agreed that the acft was over land when a sharp left turn was made back toward the water. During this turn, the acft struck trees & crashed aprx 40 ft from the shoreline. An autopsy & toxicological tests of the plt failed to reveal any inflight incapacitation.
