## Narrative

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

AIRCRAFT WAS PRACTICING TOUCH AND GO?S. THE CREW DESCRIBED THE LANDINGS AS NORMAL, NO HARD LANDINGS, AND THERE WERE NO STRONG CROSS WINDS DURING THE TIME OF THE FLIGHT. ON THE LAST LANDING DURING ROLL OUT ON RUNWAY, THE CREW DESCRIBED WHAT THEY THOUGHT WAS A FLAT TIRE, THEN THE PROP STRUCK THE RUNWAY. THERE WERE NO INJURIES, BUT IT WAS DISCOVERED THE R/H MLG STRUT HAD BROKEN DURING THE ROLLOUT.

THERE WAS DAMAGE TO THE LANDING GEAR STRUT, AND R/H FLAP, AND SOME DAMAGE TO THE REAR SPAR AREA OF THE WING. THE REAR SPAR DAMAGE APPEARS TO HAVE BEEN CAUSED BY THE BROKEN OFF PORTION OF THE STRUT.

CLOSER EXAMINATION OF THE BROKEN STRUT REVEALED CORROSION THROUGH THE THICKNESS OF THE SLIDING MEMBER TUBE MATERIAL AT THE ATTACHMENT BOLT HOLE, INDICATING A CRACK OR CORROSION WEAKENED THIS STRUT PRIOR TO ACCIDENT.
