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

The pilot reported that, during an agricultural application flight, his attention was focused "on a shed and electrical lines." While maneuvering to the north at a low altitude, the airplane's right wing collided with an unseen galvanized windmill tower. He reported that the tower had blended into the gray sky. He attempted to control the airplane, but it descended and impacted terrain. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
