NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
As the pilot set climb power the acft began to settle. Full power was applied but the descent continued. The pilot dumped the chemical load and landed in a rice field. During recovery of the wreckage the flexible induction air duct partially collapsed restricting air flow to the carburetor. According to the pilot 2 of the 4 propeller blade pitch change links failed in flt causing the 2 blades to feather resulting in the power loss. An FAA inspector examined the pitch links but could not determine if the failure was impact related.
