What happened
The pilot was operating a tailwheel-equipped airplane under challenging visual conditions characterized by flat light. As the aircraft approached the runway, an area of plowed snow was visible at the approach end of the strip. The main landing gear touched down approximately 15 feet short of the cleared, plowed portion of the runway surface.
Following touchdown, the aircraft's nose pitched downward abruptly. The airplane slid off the edge of the runway pavement and subsequently nosed over, coming to rest in an inverted or damaged configuration on the ground.
The investigation
The accident investigation focused on the circumstances surrounding the landing rollout. Investigators noted the presence of plowed snow at the approach end of the runway, which may have affected visual depth perception for the pilot during the final approach phase.
Findings
Contributing factors to this accident included the flat light conditions which likely impaired the pilot's ability to accurately judge altitude and distance to the runway threshold. The decision to land with a visible plowed snow area at the approach end may have also played a role in the misjudgment of the touchdown point.
Safety message
Pilots operating tailwheel-equipped aircraft should exercise extreme caution during landing operations in flat light conditions. Visual references can be deceptive, making it difficult to judge height above the ground accurately. It is critical to ensure adequate visibility and to be aware of runway surface conditions, including snow or ice, which can obscure visual cues and affect braking performance.
