Probable cause

Pilot's failure to verify the amount of chemical load on the airplane prior to takeoff which resulted in the airplane being heavier than expected. Contributing to the accident was loading crew not following the pilot's instructions.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot stated that on the day of the accident he had sprayed 13 loads of fertilizer and was beginning the 14th load when the accident occurred. The pilot informed the loading crew to load 400 gallons of fertilizer, which was the same amount that he had used on the previous flights. The pilot initiated the takeoff and the airplane became airborne, but was unable to gain enough altitude to clear the corn crop at the end of the airstrip. The airplane received substantial damage to the fuselage when it settled into the corn. The pilot reported that after the accident, it was determined that the hopper had been filled with 480 gallons of fertilizer. The pilot stated that since he cannot see how much fertilizer was loaded from his seat, he has to trust the loading crew to properly load the fertilizer. The pilot reported there were no mechanical issues with the airplane that would have prevented normal operation.
