## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

HELICOPTER WAS INVOLVED IN AERIAL APPLICATION WHEN THE ENGINE FAILED, THE PILOT AUTO ROTATED THE ACFT, AND THE ACFT STRUCK A LOG AND ROLLED OVER. (.19) ENGINE FAILED OVER TREES, PILOT AUTOROTATED LANDED ON A LOG, HELICOPTER ROLLED OVER SUSTAINING SUBSTANTIAL DAMAGE, INVESIGATION CONTINUES. (.4) ACCORDING TO THE PILOT, WHILE MAKING A 180 DEGREE TURN, THE BOOST PUMP FAIL LIGHT CAME ON. SHORTLY AFTERWARDS THE ENGINE SHUT DOWN AT ABOUT 150 FEET AGL. HE SELECTED A FIELD FOR AN EMERGENCY LANDING AND ENTERED AN AUTOROTATION. DURING THE TOUCHDOWN PHASE OF THE AUTOROTATION, THE HELICOPTER COLLIDED WITH A LOG AND ROLLED OVER. ACCORDING TO THE PILOT, THERE WAS INSUFFICIENT RPM TO STOP THE ROLL OVER. EXAMINATION OF THE ENGINE CONCLUDED THAT THE FUEL SUPPLY SYSTEM HAD AN AIR LEAK BETWEEN THE FUEL TANK AND THE ENGINE DRIVEN FUEL PUMP. ALSO BOTH THE AIRFRAME AND ENGINE FUEL FILTERS WERE CLOGGED WITH AN UNIDENTIFIABLE BROWNISH, JELLY-LIKE SUBSTANCE. A REVIEW OF THE MAINTENANCE LOG REVEALED THAT THE LAST 100 HOUR INSPECTION WAS 98 HOURS BEFORE THE ACCIDENT. THERE WERE NO FURHTER INDICATIONS OF ANY OTHER MAINTENANCE DONE ON THE FUEL SYSTEM.                                                            (-23) ENGINE FAILED OVER TREES, PILOT AUTOROTATED LANDED ON A LOG, HELICOPTER ROLLED OVER SUSTAINING SUBSTANTIAL DAMAGE, INVESTIGATION CONTINUES.
