## Narrative

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

GLIDER LOST ELEVATOR CONTROL AND MADE AN EMERG LANDING IN THE DESERT.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           (.4) THE GLIDER IMPACTED TERRAIN AND THE PILOT REPORTED THAT HE LOST ELEVATOR CONTROL. THE BOLT CONNECTING THE PUSHROD TO THE ELEVATOR WAS FOUND, BUT THE ATTACHING NUT WAS NOT FOUND.  THE EUROPEAN PRODUCTION GLIDER HAD A TOTAL TIME OF 4 HOURS SINCE MANUFACTURE.  THE METALLURGIST WHO EXAMINED THE BOLT REPORTED THE FIRST THREE THREADS OF THE ACCIDENT BOLT DID NOT HAVE DEBRIS IN THE ROOTS; HOWEVER, PROPER ENGAGEMENT OF THE LOCKNUT WOULD CAUSE SIX THREADS TO BE FREE OF DEBRIS.  AN EXEMPLAR LOCKNUT IN THE HAND-TIGHTENED ONLY POSITION (WITHOUT ENGAGING THE BLUE PLASTIC LINING OF THE LOCKNUT) CAUSED THE NUT THREADS TO WIPE MATERIAL FROM THE ROOTS OF THE FIRST THREE BOLT THREADS

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: The disconnection of the elevator control attachment nut due to improper installation by the manufacturer, which resulted in the pilot's loss of control.
