## Narrative

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

(-23) MR. LEWIS WAS LANDING WEST ON A REMOTE "BUSH" GRAVEL RUNWAY. HE DESCRIBED THE RUNWAY TO BE APPROXIMATELY 50 X 1000 FEET, GRAVEL, LEVEL IN ALL DIRECTIONS AND SMOOTH. HE FURTHER STATED THAT THE RUNWAY WAS MAINTAINED AND REGULARLY USED BY PROPERTY OWNER IN THE AREA. DURING WHAT HE DESCRIBED AS A NORMAL, MAIN GEAR LANDING AND ROLL OUT, THE RIGHT MAIN LANDING GEAR COLLAPSED. AS THE AIRPLANE SLID ON THE GRAVEL, THE RIGHT GEAR STRUT INCLUDING THE RIGHT GEAR BOX WAS TORN OUT OF THE FUSELAGE. THE AIRPLANE SUBSEQUENTLY SUSTAINED SUBSTANTIAL DAMAGE TO THE FUSELAGE, COWLING, ENGINE, PROPELLER, RIGHT HORIZONTAL AND RIGHT WING WHILE DECELERATING TO A STOP. POST ACCIDENT, HE DISCOVERED THAT THE RIGHT MAIN WHEEL, TIRE, BRAKE ASSEMBLY AND ATTACHMENT BOLSTS SEPARATED FROM THE RIGHT MAIN GEAR AXLE ALMOST IMMEDIATELY AFTER TOUCH DOWN AND AS A SINGLE UNIT. HE STATED THAT THE FAILURE OF THE RIGHT WHEEL ASSEMBLY ATTACHMENT BOLTS ARE IN HIS OPINION, THE SINGULAR CAUSE OF THIS ACCIDENT.
