Accident Overview
A turbine-powered agricultural airplane, a 2005 model, sustained major structural damage aft of the engine firewall following a forced landing. The accident occurred during a local aerial application flight after the aircraft experienced a loss of engine power.
Pilot and Flight Details
The commercial pilot, who held 8,500 hours of flight experience and was not instrument rated, reported that he encountered problems with the onboard agricultural navigation system before proceeding to the spraying field. Despite the issue, he elected to continue the flight.
Engine Failure and Forced Landing
During the en route segment to the field, the engine surged multiple times and subsequently lost power. The pilot attempted a forced landing in a pasture. While on approach, a sharp turn was necessary to avoid a fence, leading to a hard landing and loss of directional control. The payload of 5,500 pounds of chemicals remained in the hopper; investigators were unable to determine why the pilot did not jettison the load after the engine failure.
Post-Accident Examination
A Federal Aviation Administration inspector examined the aircraft at the accident site. The inspection revealed less than one cup of fuel in one tank and less than five gallons in the other. The completed Pilot/Operator Aircraft Accident/Incident Report (NTSB Form 6120.1) was not submitted by either the pilot or the operator.
