Event ANC11CA097

Factual narrative

The pilot was landing at an unlighted, gravel runway, at dusk, when he inadvertently touched down in a grass-covered drainage ditch, which was right of the gravel runway. During the landing roll, the airplane collided with a drainage culvert, sustaining substantial damage to the right wing and fuselage. The pilot noted in his written statement to the NTSB that he was unable to discern the difference between the gravel runway and grass-covered terrain due to the low-light conditions, and he mistakenly selected the grass-covered ditch. The pilot indicated that there were no mechanical anomalies with the airplane.
