Analysis

The float equipped aircraft crashed into trees after taking off from samonn creek reservoir while departing with overnight campers. The reservoir was located in a steep walled canyon. The pilot reported that he took off heading north into the canyon, raised the flaps, and reduced the power to 2500 RPM and 25 inches manifold pressure. He reported that he kept the nose lowered to gain airspeed, but encountered a downdraft, shortly after takeoff, while making a left turn. The aircraft settled into trees along the shore.
