## Analysis

WHILE SPRAYING LIQUID FERTILIZER, THE PLT NOTICED THAT THE FUEL INDICATION WAS DROPPING RAPIDLY. HE STATED THAT HE TRIED TO RETURN TO THE DEPARTURE POINT, BUT WAS UNABLE. WHEN THE ENGINE LOST POWER, HE JETTISONED THE REMAINDER OF HIS LOAD & LANDED IN A PASTURE. DURING THE LANDING, THE ACFT COLLIDED WITH A BARBED WIRE FENCE. AN EXAMINATION REVEALED THAT A FUEL LEAK OCCURRED WHERE A FUEL LINE RUBBED AGAINST AN OIL COOLER LINE.
