Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The pilot's selection of unsuitable terrain for landing adjacent to the runway. Factors include sun glare encountered at the time of the landing attempt.
Analysis
The pilot noted that the winds were calm at his destination airstrip. He approached to the east, into the morning sun, in order to land upslope on the grass airstrip. He said he positioned the plane in the center of the light green fresh mowed area, which he learned after landing was not all runway. He stated that the sun was in his eyes on final approach, obscuring details of the landing area. He touched down about 250 feet from the approach end with full flaps and a touch of power, using standard soft field techniques. The airplane slid down the side slope to the left and would not respond to right rudder inputs, until the left wing contacted a large wooden fence post and about four feet of the left wingtip separated. He stated that the day before the flight he obtained an airport briefing from a local pilot familiar with the airport. Sun azimuth at the time of the accident was 109.9; elevation was 49.4 degrees.
