Read the full NTSB narrative

Shortly after takeoff, the airplane's engine lost power. The airplane hit trees and then terrain, resulting in substantial damage. A postaccident examination revealed that one spark plug and its lead assembly had separated from its cylinder. Examination of the threads and the orifice on the cylinder revealed no anomalies. Further examination revealed that the remaining spark plugs were loose but had not separated from their respective cylinders. It is likely that the spark plug that had become separated was also loose and not properly secured during maintenance. Examination of the airplane's engine, airframe, and systems revealed no additional anomalies that would have precluded normal operation.
