Aircraft involved

Factual narrative

THE AIRCRAFT COLLIDED WITH AN IRRIGATION PIPE LINE AND FENCE DURING ROLLOUT OF A FORCED LANDING AFTER ENGINE FAILURE. THE ENGINE STOPPED WHILE THE AIRCRAFT WAS CRUISING EN ROUTE. THE PILOT REMAINED IN RADIO CONTACT THROUGHOUT THE EMERGENCY AND LANDED IN A FIELD OF GRAIN STUBBLE AND NEW CROPS. AN ENGINE TEARDOWN REVEALED A HOLE IN THE #4 PISTON. THIS HOLE HAD PRESSURIZED THE CRANKCASE FORCING OIL OUT OF THE BREATHER UNTIL OIL DEPLETION CAUSED ENGINE STOPPAGE. ALSO, A TRACE OF CARBON TRACKING WAS FOUND ON THE RIGHT DISTRIBUTOR BLOCK FROM THE #4 LOCATION TO ANOTHER STATIONARY ELECTRODE.
