## Narrative

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

AFTER WHAT WAS REPORTED AS A NORMAL LANDING, DURING ROLL-OUT, THE RIGHT LANDING GEAR COLLAPSED.  THE PILOTS STATED THAT THE AIRCRAFT WAS ONLY TRAVELLING AT ABOUT 5-10 MPH WHEN THEY FELT AN OSCILLATION IN THE LANDING GEAR AND THOUGHT THAT IT MIGHT BE A FLAT TIRE.  IT WAS DISCOVERED THAT THE RIGHT WHEEL WAS TURNED SIDWAYS AND THE FORWARD TRUNION FITTING HAD BEEN RIPPED OUT OF THE AIRCRAFT STRUCTURE CAUSING THE GEAR TO FOLD AFT.  EXAMINATION OF THE RIGHT LANDING GEAR, REVEALED THAT THE CENTER SCISSORS LINK BOLT WAS BROKEN NEAR THE THREADED END.
