Read the full NTSB narrative

The airline transport pilot departed in a single-engine, low-wing airplane for the purpose of aerial application. He reported that during takeoff, at approximately 100 feet above ground level (AGL), the engine lost partial power. He was unable to maintain altitude, and made a controlled descent into small trees off the end of the runway and then nosed over. An FAA inspector examined the airplane, and reported there was sufficient fuel on board for the flight and both water accumulators were empty. The airplane's last annual inspection was on March 21, 2007. At the time of inspection, the airplane had a total of 7,392 hours. The engine had 7,500 total hours, and 100 hours since it was last inspected. The cause for the partial loss of engine power was not determined.
