Read the full NTSB narrative
ABOUT 45 MINUTES INTO THE FLIGHT, THE NUMBER SIX CONNECTING ROD EXPERIENCED A FATIGUE FAILURE, AND CAUSED CATASTROPHIC DAMAGE TO THE ENGINE CRANKCASE. THE FRACTURING OF THE CASE RESULTED IN A LOSS OF OIL, AND THE LOSS OF OIL PRESSURE RESULTED IN A RUNAWAY PROPELLER. THE PILOT THEN EXECUTED A SUCCESSFUL FORCED LANDING, BUT THE AIRCRAFT WAS DAMAGED WHEN IT COLLIDED WITH AN IRRIGATION PIPE AND A FENCE DURING THE LANDING ROLL. THE AIRCRAFT, WHICH IS USED EXTENSIVELY FOR PROFESSIONAL AIR SHOW AEROBATICS, IS POWERED BY AN ENGINE THAT IS CLASSED AS EXPERIMENTAL BECAUSE IT CONTAINS HIGH COMPRESSION PISTONS.
