Read the full NTSB narrative
The pilot-in-command departed the airport in a Grumman G-164A spray plane. En route to the destination field, and while overflying hilly terrain, the aircraft's tail wheel impacted the ground, followed by the main gear. The aircraft continued over an embankment, nosing over while crossing a paved road, before coming to rest and burning. There was no evidence that the pilot jettisoned the 2,040 pound herbicide load. Propeller slash marks early in the ground track indicated high engine RPM at the initial ground impact. Additionally, toxicological evaluation of samples from the pilot-in-command revealed 0.002 ug/ml of Tetrahydrocannabinol detected in blood, 0.08 ug/ml of Tetrahydrocannabinol Carboxylic Acid detected in blood, and 0.035 ug/ml of Tetrahydrocannabinol Carboxylic Acid detected in urine indicating fairly recent (within several hours) use of Marihuana.
