NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
Two pilots departed in the amateur built airplane for a local flight. About 10 miles from the departure airport, the airplane was observed to descend into the terrain. The activity of the airplane prior to the accident and/or the individual operating the airplane controls at the time was not determined. Subsequent to the accident an examination of the airplane determined that the carry-through portion of the horizontal stabilizer, which included the forward attachment for the vertical stabilizer, had become disconnected in flight. The particular part was not found. The entire right horizontal stabilizer and the outboard half of the right elevator departed the airplane in-flight. The lower rudder attach fitting bolt was missing at the impact site, and there was no evidence that the bolt was in place at the time of the accident.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: was the in-flight disconnection of the horizontal and vertical stabilizer forward attachments. Full narrative available
