The NTSB's narrative final · quoted from the NTSB record

The pilot stated that he was attempting a landing into the sun with agricultural chemical on the windshield. He said that a sudden air burst pushed the airplane down, which resulted in a hard landing. The airplane then bounced and impacted the runway causing substantial damage to the fuselage. Weather reports for the area did not indicate the presence of weather that would have resulted in an air burst.
