## Analysis

THE ACFT SLID ACROSS A ROAD AND SLID PARALLEL TO A FENCE UNTIL THE ACFT HIT A FENCE POST DURING A FORCED LANDING. THE ACFT WAS ON A TEST FLT AFTER MAINTENANCE WHICH INCLUDED ADJUSTMENT OF THE ABSOLUTE CONTROLLER. THE BEFORE TAKEOFF CHECKSWERE MADE AND EVERYTHING SEEMED NORMAL. DURING TAKEOFF AT 500 FT AGL THE ENGINE LOST POWER. THE PILOT TURNED ON THE BOOST PUMP AND ENGINE REGAINED POWER THEN QUIT. THE PILOT SWITCHED TANKS AND CHECKED MIXTURE BUT ENGINE WOULD NOT START.A LANDING WAS MADE ON A PUBLIC ROAD WITH GEAR AND FLAPS DOWN. THE EXAMINATION AND POST ACCIDENT TEST RUNS OF THE ENGINE SHOWED THAT THE ABSOLUTE CONTROLLER WAS OUT OF ADJUSTMENT WHICH CAUSED AN OVER RICH MIXTURE. BY ADDING THE BOOST PUMP AFTER ENGINE FAILURE IT AGGRAVATED THE SITUATION TO THE POINT OF FLOODING THE ENGINE.
