NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private certificated pilot was departing a small lake in a float-equipped airplane. The pilot said he operated from the lake numerous times, and landed on the lake about 45 minutes before the accident to pick up cargo for his fishing camp. The pilot said that when he landed, the wind was from the west, and when he began to taxi on the lake for departure, the wind was calm. The pilot began the takeoff run toward the west, and he said the airplane came up on step. He said his ground speed seemed fast, but the airspeed was low. He said the airplane became airborne near the edge of the lake shore, but the tail portion of the float assembly struck a six inch high berm at the edge of the lake. The airplane came to rest on a road located along the shoreline of the lake. The airplane received damage to the float assemblies, the propeller, and the tail. Following the accident, the pilot said that witnesses told him that as he taxied onto the lake for departure, the wind began to blow from the southeast about 15 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's inadequate evaluation of the wind conditions. A factor in the accident was the presence of a tailwind.
