Accident · substantial damage

Jun 21, 2021 · Leoti, KS

The pilot’s loss of visibility in the cockpit due to foam created by the chemicals loaded in the hopper, which resulted in his inability to maintain airplane control during low-level flight and an impact with terrain. Contributing to the accident was the combining of chemicals known to produce foam and the pilot’s failure to perform a jar test before flight as recommended.
