Narrative:
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.
