What happened
The pilot was conducting his third aerial application flight of the day when he attempted to depart northward from a 2,400-foot-long dirt strip. Conditions were challenging, with a calculated density altitude of 5,200 feet and very light winds coming from the northwest. Acceleration appeared normal for the initial portion of the takeoff roll. However, approximately two-thirds of the way down the runway, the pilot reported that the aircraft seemed to suddenly pick up a tailwind, which likely contributed to the inability to gain sufficient lift.
In an effort to reduce weight and achieve flight, the pilot dumped the load of chemicals. Despite this action, the aircraft failed to become airborne. The runway ended at a two-foot-high levy. As the main landing gear struck this obstacle, the aircraft bounced into the air briefly before crashing. The engine was examined following the accident, but no evidence was found to explain the reported power loss or performance issues.
The investigation
A post-accident examination of the engine was conducted to determine if mechanical failure contributed to the incident. Investigators found no evidence to support the pilot's report of a sudden power loss or any other mechanical anomaly that would account for the aircraft's inability to fly.
