During an agricultural application flight, a gearbox chip detector light prompted the pilot to return to the airport. The aircraft landed with a tailwind, skidded left off the runway, struck a berm, and sustained substantial wing damage.

Pilot Actions After Warning Light

While on departure for an agricultural application flight, the pilot observed illumination of the gearbox chip detector light approximately five miles from the runway. In response, the pilot decided to reverse course and return to the airport.

Landing and Loss of Control

The airplane landed on runway 34 with a reported tailwind. According to the pilot, during the landing roll, the aircraft's nose made a sharp left turn as beta and braking were initiated. The airplane subsequently skidded and exited the left side of the runway, entering a field where it impacted a berm. The accident resulted in substantial damage to the wings.
