What happened
The pilot was conducting an approach to his home airport when he extended the final segment of the flight path beyond his standard touchdown zone. Upon reaching the runway threshold area, the aircraft made contact with the surface, which consisted of soft sod covered by recently mowed grass clippings. These clippings concealed deep ruts in the ground that were not visible to the pilot during the landing roll.
Upon impact with the uneven terrain, the aircraft encountered significant resistance and instability. The pilot was unable to maintain directional control of the airplane. The aircraft veered sharply to the right side of the runway centerline. It departed the paved surface entirely and continued its trajectory toward nearby vegetation. The airplane subsequently collided with a group of trees.
The investigation
Examination of the accident site revealed that the runway surface conditions played a critical role in the loss of control. The sod was soft, and the presence of recently mowed grass clippings obscured deep ruts in the ground. These hidden irregularities disrupted the landing gear's contact with the surface, leading to the immediate loss of directional stability.
Findings
The primary factor contributing to this accident was the pilot's decision to land beyond the normal touchdown point on a runway with compromised surface conditions. The soft sod and concealed ruts prevented effective braking and steering control after initial contact. This resulted in the aircraft departing the runway environment and striking trees. The lack of visibility due to the grass clippings was a significant hazard that could not be mitigated once the aircraft had already committed to the landing phase.
