NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE PILOT REPORTED THAT DURING CLIMBOUT HE BELIEVED THE AIRCRAFT SUSTAINED A PARTIAL LOSS OF ENG PWR. HE DUMPED HIS CHEMICAL LOAD AS THE ACFT DESCENDED. HE MANEUVERED THE ACFT TO AVOID SEVERAL OBSTACLES, BUT THE LEFT GEAR EVENTUALLY SEPARATED AFTER THE ACFT LANDED IN SOFT DIRT. A POST ACCIDENT EXAMINATION OF THE AIRCRAFT AND THE ENGINE FAILED TO ACCOUNT FOR THE REPORTED PARTIAL LOSS OF ENGINE PWR; THE DISASSEMBLY OF THE ENG DID NOT REVEAL ANY PRE-IMPACT MALFUNCTION.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PARTIAL FAILURE OF THE ENGINE FOR UNDETERMINED REASONS WHICH RESULTED IN A FORCED LANDING. A FACTOR RELATED TO THE ACCIDENT WAS THE SOFT DIRT.
