NTSB narrative
Shortly after takeoff during an agricultural application flight, approximately 834 hours since the turbine blades were installed, the engine experienced a loss of power resulting in a forced landing. Unable to dump his chemical load due to cars on a highway, the pilot executed a forced landing in a field resulting in substantial damage to both wings. Examination of the engine revealed that during repair of the compressor turbine disk in 2005, incorrect part number Federal Aviation Administration (FAA) Parts Manufacturer Approval (PMA) turbine blades were installed in all positions of the compressor turbine disk of the accident engine. The engine was approved for return to service. One of the turbine blades failed due to fatigue causing the remaining blades to fracture due to overstress.
Probable cause
Loss of engine power due to the installation of incorrect turbine blades on the compressor turbine disk during repair of the disk assembly.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
