## Analysis

DURING TAKEOFF FROM A MUDDY FIELD WITH A DENSITY ALTITUDE OF 7253 FEET THE AIRCRAFT FAILED TO CLEAR A BOUNDARY FENCE. THE PASSENGERS STATED THE STALL WARNING SOUNDED STEADILY FROM TAKEOFF UNTIL IMPACT WITH THE GROUND. AFTER THE COLLISION WITH THE FENCE THE AIRCRAFT WENT ACROSS A FIELD, HIT A ROAD EMBANKMENT WITH ITS TAIL SKID AND CAME TO REST IN AN ADJOINING MEADOW. NO EVIDENCE OF ENGINE MALFUNCTION WAS FOUND.
