## Analysis

WHILE EN ROUTE TO A CUSTOMER'S FIELD, AT APRX 350 FT AGL OVER A WOODED AREA, THE ENGINE LOST POWER. THE PLT RELEASED THE LOAD, AND SUBSEQUENTLY, HE LANDED THE ACFT IN THE TREE TOPS. DURING THE LANDING, THE ACFT SHEARED OFF A LARGE TREE, KNOCKED ANOTHER TREE OVER & CAME TO REST IN A 50 DEG, NOSE DOWN ATTITUDE. APPROX 40 GAL OF FUEL WAS FOUND ON BOARD. HOWEVER, A DRAIN NIPPLE AT THE BASE OF THE WOBBLE PUMP STRAINER HAD FAILED & ALLOWED CAVITATION OF THE ENGINE DRIVEN FUEL PUMP. THE FAILED COMPONENT (ROCKWELL PN 64040) FAILED AFTER 1833 HRS OF OPERATIONS.
