Accident Description
The accident involved a landing on a farm airstrip that had been recently plowed and rolled. The pilot configured the airplane with 30 degrees of flaps for the approach and landing. The landing was made to the west.
During the landing roll-out, the airplane's wheels penetrated the soft surface of the plowed and rolled dirt. This caused the nose of the airplane to pitch forward, resulting in the airplane flipping onto its back. The pilot reported that, despite applying full up elevator input, he was unable to prevent the nose-over.
Pilot Actions
The pilot had selected 30 degrees of flaps for the landing. He reported that after touchdown, the wheels sank into the dirt, and even with full up elevator applied, the airplane continued to nose over. The airplane came to rest inverted on the airstrip.
