## Discrepancy

DURING ROLL-OUT, PILOT LOST DIRECTIONAL CONTROL AND AIRCRAFT VEERED OFF RUNWAY INTO THE DIRT.  AFTER CONTACTING UNEVEN TERRAIN, THE LT MLG STRUT COLLAPSED AFT CAUSING DAMAGE TO LT MLG FAIRINGS, FUSELAGE, AND LT STABILIZER/ELEVATORS.  INSPECTION SHOWED THE P/N S2138-1 BOLT HAD BROKEN INSIDE STRUT ALLOWING STRUT TO ROTATE AFT.  METALLURGICAL ANALYSIS DETERMINED THE BOLT WAS PREVIOUSLY CRACKED.  SUBMITTER RECOMMENDED A SAFE LIFE LIMIT BE ESTABLISHED.
