Probable cause

The pilot's poor judgement, due to consumption of alcohol, and his failure to maintain directional control of the aircraft during the takeoff run.

Analysis

During a water takeoff, the pilot lost directional control of the floatplane & it collided with a bank. No preimpact part failure or malfunction of the aircraft was found. The pilot submitted to an alcohol intoximeter test about 24 min after the accident. The test indicated a blood/alcohol level of 269 mg% (0.269%).
