The NTSB's narrative final · quoted from the NTSB record
The airplane contacted a corn crop following a loss of control during takeoff. The pilot reported that on takeoff at an airspeed of about 50 miles per hour the right aft corner of the hopper lid became unsecured. He reported that the fungicide in the hopper sprayed out and covered the windshield. The pilot reported that because of hazards on both sides and at the end of the runway he felt it was best to continue the takeoff at full power. He stated that he was able to see out the lower right corner of the windshield which was only partially obscured. The pilot stated he then lost control of the airplane and the lower left wing contacted the corn crop on the left edge of the airstrip. The airplane was turned into the crop where it came to rest. Inspection of the right rear latch on the double gang-bar type latch revealed that the latch was bent.
