Narrative:
This was the pilot's first flight of the morning, and he had completed spraying 35 acres of cotton. The pilot was flying from east to west, and had crossed over some trees and dropped down for a swath run when the right wing struck an irrigation sprinkler pivot. About 5-6 feet of the right wing and half of its aileron separated from the airplane. The pilot flew the airplane back to the staging strip and landed without further incident. The pilot stated that the sun was in his eyes, and it hampered him from seeing the irrigation pivot in time to avoid it.

Probable Cause: the pilot's failure to maintain obstacle clearance. A contributing factor was the sun glare.
