## Analysis

WHILE IN CRUISE FLT NEAR AN ARPT, THE PROP SEPARATED. PLT WAS GIVEN VECTORS TO ARPT & ENTERED PATTERN FOR LNDG. DOWNWIND LEG WAS EXTENDED DUE TO STRONG TAILWIND. STRONG HEADWIND ON FINAL CAUSED ACFT TO LAND SHORT. DURING LANDING ROLL ACFT COLLIDED WITH TWO FENCES. EXAMINATION OF ACFT REVEALED 6 PROP MOUNT BOLTS FAILED DUE TO FATIGUE AS A RESULT OF IMPROPER PLACEMENT OF PROP MOUNTING SHIM BETWEEN ENGINE CRANKSHAFT FLANGE AND STARTER GEAR FLANGE. ACFT MANUAL STATED PROP MOUNT BOLTS MAY FAIL DUE TO RELATIVE MOVEMENT BETWEEN THE TWO FLANGES IF SHIM IS NOT INSTALLED. CORRECT PLACEMENT OF THE SHIM IS BETWEEN THE PROP FLANGE & THE STARTER GEAR FLANGE. SUDDEN ENG STOPPAGE APROX 45 HRS EARLIER RESULTED IN PROP REMOVAL, OVERHAUL, & REINSTALLATION.
