What happened
During the flight, the pilot momentarily diverted his attention from the controls to retrieve a fire extinguisher from the floor area and return it to its bracket beneath the seat. Upon regaining visual contact with the external environment, the pilot observed a hill directly in the flight path. In an attempt to clear the obstacle, the pilot applied full power and pulled back on the yoke, which caused the aircraft to impact the hillside.
Following the initial impact, the aircraft remained airborne and entered a cloud layer. While flying through the clouds, the pilot realized the aircraft was approaching a stall condition. To prevent the loss of airspeed, the pilot lowered the nose of the aircraft. This maneuver resulted in a second impact with the same hillside, which ultimately caused the aircraft to nose over.
