The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he intended to practice takeoffs and landings, and he completed the first takeoff and landing without incident. While on the base leg of the landing pattern after the second takeoff, the pilot pushed the throttle forward, and the engine stopped producing power. He was unable to regain engine power, so he made a forced landing into a small clearing, which resulted in substantial damage and a serious injury. The postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The fuel-injected engine was shipped to the manufacturer for further examination and an engine run, during which the engine demonstrated the ability to produce rated horsepower.
