DURING A TURN TO REVERSE DIRECTION WHILE DISPERSING CHEMICALS OVER A PEANUT CROP, THE ENGINE LOST POWER. THE PILOT DUMPED THE LOAD OF CHEMICALS AND MADE A HARD FULL STALL FORCED LANDING IN THE PEANUT FIELD. INSPECTION OF THE ENGINE REVEALED THAT THE LEFT MAGNETO IMPULSE COUPLING HAD FAILED. THE COUPLING FRAGMENTS BECAME LODGED IN THE ACCESSORY CASE OF THE ENGINE AND SEPARATED THE CAMSHAFT DRIVE GEAR WHICH RENDERED THE ENGINE POWERLESS. AD78-09-07 R3 REQUIRES INSPECTION OF THE IMPULSE COUPLING AT INTERVALS NOT TO EXCEED 500 HOURS TIME IN SERVICE. AT THE TIME OF THE ACCIDENT THE SUBJECT MAGNETO HAD 576 HOURS TIME IN SERVICE AND HAD NOT BEEN INSPECTED.
