The NTSB's narrative final · quoted from the NTSB record

THE AERIAL APPLICATION HELICOPTER CRASHED JUST AFTER LIFT-OFF AFTER SUSTAINING A POWER FAILURE, THE PLT STATED THAT HE THOUGHT THE REASON FOR THE FAILURE COULD HAVE BEEN FUEL STARVATION SINCE HE HAD OBSERVED SOME FOREIGN MATTER IN THE FUEL WHEN HE DRAINED THE SUMP DURING THE PREFLT INSPECTION OF THE ACFT. A POST ACCIDENT EXAM REVEALED NO EVIDENCE OF ANY FUEL ODOR OR FUEL SPILL IN OR AROUND THE CRASH SITE. ONLY A SMALL AMOUNT OF FUEL WAS FOUND IN THE GASCOLATOR. THERE WAS NO FUEL PRESENT IN THE TANK ALTHOUGH THE FUEL TANK WAS ON ITS SIDE AND THE CAP WAS MISSING FROM THE TANK. NO EVIDENCE OF ANY WATER OR FOREIGN MATTER WAS DETECTED IN THE FUEL SYSTEM. THE FLT WAS OPERATING CONTRA TO FAR PART 137, IN THAT THE OPERATOR DID NOT HAVE A FAA CERTIFICATE FOR AGRICULTURAL OPERATIONS.
