A pilot intentionally ground looped an airplane after a short field landing on a grass runway, avoiding a ravine but impacting trees. The forward left wing spar was fractured. No mechanical anomalies were reported.

Accident Sequence

The pilot conducted a short field landing approach by pointing the aircraft at the approach end of a 2,350-foot-long, 100-foot-wide grass runway. Upon touchdown, the pilot applied brakes, and the deceleration seemed normal. However, due to the pilot's cockpit position and the three-point landing attitude, the pilot could not see the end of the runway until it was too late.

Evasive Action

To prevent the aircraft from traveling off the runway into a ravine, the pilot intentionally performed a ground loop. The airplane turned 90 degrees and subsequently struck trees.

Witness Accounts

According to a Federal Aviation Administration inspector, witnesses reported that the approach speed was "way too fast for the short runway."

Aircraft Examination

Post-incident inspection revealed a fracture in the forward left wing spar. The pilot reported no mechanical anomalies with the airplane.
