## Narrative

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

THIS CAUSED A LOSS OF CONTROL TO THE AIRCRAFT, PILOT WAS ABLE TO LAND THE AIRCRAFT BUT DURING THE LANDING THE AIRCRAFT RIGHT WING HIT THE GROUND, BECAUSE OF THE CONTROL ISSUES FROM THE MISSING BOLT, CAUSING SUBSTANTIAL DAMAGE TO THE AIRCRAFT.
