Read the full NTSB narrative

The pilot reported that prior to departure, the engine had been running rough and that he aborted two takeoffs prior to the flight. After changing the spark plugs, the flight departed. About ten minutes after departure, the engine lost power. During a left turn to a clearing over heavy timber terrain, the aircraft lost airspeed and went into a dive. The aircraft descended about 800 feet before the pilot was able to pull the nose up just prior to colliding with the terrain. The pilot reported that he thought that this aircraft met the requirements of an ultralight and had not maintained this aircraft in accordance with an annual inspection program. It was later determined that this aircraft did not meet the ultralight requirements and should have been issued an airworthiness certificate and registered. The cause of the loss of power was not determined.
