## Narrative

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

ON THE MORNING OF 09/10/2021, N9343B, A CESSNA CE175 WITH A TAILWHEEL CONVERSION RETURNED TO HSR AIRPORT FROM WALL,SD AIRPORT AND LANDED ON RUNWAY 24 HSR. ON LANDING ROLLOUT THE RIGHT MAIN GEAR COLLAPSED CAUSING SUBSTANTIAL DAMAGE TO THE AIRCRAFT. ^PRIVACY DATA OMITTED^PILOT REPORTED ACCIDENT IMMEDIATELY.  ON 09/11/2021, INSPECTORS FROM THE RAP FSDO INVESTIGATED AND FOUND AN AIRCRAFT WITH THE RIGHT MAIN LANDING GEAR COMPLETELY SEPARATED FROM THE AIRCRAFT FUSELAGE, AND SUBSTANTIALLY DAMAGED. FURTHER INVESTIGATION OF THE GEAR BOX AREA REVEALED A BROKEN MAIN LANDING GEAR LEG BOLT IN THE GEARBOX ASSEMBLY ON THE AIRCRAFT. FURTHER INVESTIGATION OF THIS ASSEMBLY SHOWED THAT THE BOLT HAD BEEN LOOSE FOR  AN EXTENDED PERIOD THE BOLT HOLES WERE OVERSIZED BY LANDING GEAR LEG ACTION AS WAS THE BOLT HOLE ON THE LANDING GEAR LEG ITSELF(EGGED OUT). FURTHER SEARCH OF THE RUNWAY WITH A METAL DETECTOR DISCOVERED THE BOTTOM SEVERED HALF TO ONE THIRD OF THIS BOLT.
