Incident Overview
During a landing approach to the west on dirt runway 27, the airplane deviated from the runway centerline and subsequently collided with a set of rocks. These rocks demarcated the intersection of runway 9/27 and runway 13/31. The pilot reported that his vision was compromised by sunlight during the landing rollout, which impeded his ability to maintain directional control.
Sun Position
According to a computer-generated Sun/Moon astrological program, at the time of the incident the magnetic bearing to the sun was 255 degrees, and the sun was approximately 18 degrees above the horizon. This sun position likely contributed to the glare experienced by the pilot.
Pilot Statement
The pilot stated that the airplane had not experienced any preimpact malfunctions or failures. No further mechanical issues were reported.
Investigation Notes
The investigation focused on the sequence of events as described by the pilot and the environmental conditions. The aircraft's drift from the centerline and subsequent impact with the rocks were the primary findings. No additional causal factors have been identified from the available data.
