From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

As the pilot made a right turn over the airfield, the aircraft experienced empennage flutter, which led to a loss in directional control, then a drastic shift in center of gravity (CG). The aircraft rolled 180 degrees and impacted a lawn 10 feet north of bldg. A-503 (near intersection of merrill and bow ave). At impact, a tool box and a bench vise ejected from the aircraft. Investigation of the aircraft revealed that the support struts for the horizontal to vertical stabilizer were missing. The son of the pilot stated that his father removed the struts the day before the crash. The aircraft was the first of a new model for Skygear, inc.
