## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THIS IS A PRELIMINARY REPORT. THERE IS A CONTINUING INVESTIGATION TAKING PLACE REGARDING THIS ACCIDENT. WHEN MORE FACTS BECOME KNOWN REGARDING THIS CASE, AN AMENDED REPORT WILL BE FILED. (-23 AMENDMENT) NEITHER THE FAA NOR THE NTSB KNOWS FOR SURE WHAT CAUSED THIS ACCIDENT. HOWEVER, IT APPEARS THAT THERE WAS A MISSING BOLT FROM THE LEFT ELEVATOR BOW THAT WAS SHEARED/TWISTED AND FAILED WHICH MEANS THAT THE LEFT ELEVATOR WAS FREE FROM THE CONTROL SYSTEM AND, THEREFORE, UNCONTROLLABLE BY THE PILOT. THIS WOULD HAVE CAUSED AN INVERSE YAW CONDITION WHICH THE PILOT WOULD HAVE ATTEMPTED TO COUNTERACT WITH LEFT RUDDER AND AILERON. THIS WOULD HAVE CAUSED DRAG AND LOSS OF ALTITUDE WHICH THE PILOT WOULD HAVE ATTEMPTED TO OVERCOME WITH MORE ENGINE POWER. SINCE THE ENGINE WAS ABOVE THE LONGITUDINAL AXIS, MORE ENGINE POWER WOULD HAVE LED TO THE AIRCRAFT NOSING DOWNWARD. THE AIRCRAFT DID STRIKE THE GROUND NOSE FIRST. THE PILOT STILL HAS NO MEMORY OF THE ACCIDENT. THIS IS A FINAL REPORT UNLESS FURTHER INFORMATION BECOMES KNOWN.
