NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane collided with an irrigation standpipe while applying chemicals to a field. The pilot stated that this was the last pass over the cotton field in an easterly direction. The sun had just risen and was reflecting off a clear plastic crop cover located next to the standpipe and the glare made it difficult to see straight ahead. The pilot stated that he saw the standpipe at the last minute and attempted to maneuver around it by pulling the aircraft up. After colliding with the standpipe, he made an emergency landing and came to rest inverted. No mechanical anomalies were noted with the aircraft. According to a computer generated Sun/Moon astrological program, the magnetic bearing to the sun was 60.7 degrees, and it was approximately 14.4 degrees above the horizon.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain an adequate clearance from the irrigation standpipe due to glare from the rising sun.
