Analysis

According to witnesses, shortly after takeoff a loud 'bang' was heard and the airplane nosed down into the ground. According to the pilot, the engine lost partial power and while climbing to clear power lines, the aircraft stalled and nosed down into a tree and subsequently the ground. A FAA Inspector on-scene stated that examination of the wreckage found that the engine had impacted the tree directly at the propeller, cracking the crankcase, and substantially damaging both wings and the cockpit. Weather conditions at the time of the accident were favorable for the formation of induction system icing.
