## Narrative

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

THE PILOT REPORTED THAT WHILE BACK-TAXING TO REPOSITION FOR DEPARTURE, DURING A LEFT 180 TURN, THE RIGHT LANDING GEAR COLLAPSED.  SUBSEQUENTLY, THE RIGHT WING WAS SUBSTANTIALLY DAMAGED WHEN IT IMPACTED THE GROUND. POST-ACCIDENT INSPECTION OF THE RIGHT LANDING GEAR REVEALED THAT THE RETRACTION LUG ON THE GEAR TRUNNION SEPARATED AND THE RETRACTION BELLCRANK ARM BROKE, WHICH ALLOWED THE GEAR TO COLLAPSE AND FOLD INWARD.
