Analysis

The plt took off with little or no warmup, pushed the acft to max performance at 10 ft, performed a max performance climb to 300 to 400 ft and reduced throttle to idle. As the acft reached stall speed, the plt dived at a 45 degree angle and impacted the ground during the attempted level off.
