The NTSB's narrative final · quoted from the NTSB record
The pilot was performing an aerial application flight and had just performed his fourth pass spraying a field. While pulling up out of the field, the airplane caught a power line with the landing gear. He was able to fly for a short time but was unable to adequately control the aircraft, and performed a forced landing in the field. The aircraft impacted the ground, damaging the engine, propeller, and the landing gear. The pilot had two additional accidents within a year. Following his latest accident, the pilot verbally agreed to voluntarily surrender his aerial application operating certificate to, and at the request of, the FAA. As of this writing, the pilot had not yet surrendered his certificate.
