Probable cause

The pilot's delayed application of full power during a soft/wet field takeoff, resulting in a collision with trees during takeoff.

NTSB narrative

The director of operations for the operator stated that soft field conditions and standing water on the runway slowed the airplane during the takeoff roll. The airplane did not lift off in time to clear trees at the end of the runway and sustained substantial damage to both wings and the fuselage when it collided with the trees. The pilot reported that he used partial power at the beginning of the takeoff roll to avoid hitting standing water on the runway with full power. After passing most of the water, he applied full power, but the airplane did not accelerate like he thought it would. He recalled the airplane being in a nose-high attitude and the main wheels bouncing several times before the airplane impacted the trees at the end of the runway.
