Probable cause

The improper maneuver that unported the low fuel tank. The unsuitable terrain at the site of forced landing was a factor.

Analysis

During takeoff from a small lake, the instructor pilot allowed a student pilot to make a flat, step turn takeoff. Due to low fuel in the tanks, the fuel pickup unported and the engine stopped and started several times due to fuel starvation. The instructor was unable to recover engine power or return to the lake prior to hitting trees.
