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 an approximate 15% reduction in power during the takeoff; however, by that time, the aircraft was at the go/no-go point, and the pilot felt he had sufficient airspeed to continue. Shortly after turning left from the runway heading, the engine surged. The pilot initiated a partial dump of the 200 gallon chemical load, but was unable to achieve a positive climb rate. He then initiated dumping of the remainder of the chemical load, during which, the main landing gear contacted furrows of a plowed field and collapsed, and the aircraft slid to a stop. The density altitude was approximately 5,400 feet at the time. During examination of the engine, no reason was found for the partial loss of power.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: partial loss of engine power for undetermined reason(s). Factors relating to the accident were: high density altitude; the pilot's delay in dumping the entire chemical load, when he first perceived a power loss; and rough/uneven terrain in the emergency landing area.
