A pilot lost visual reference to the ground while maneuvering to observe coyotes in snowy terrain, resulting in a nose-over accident due to poor contrast and low ceilings.

What happened

The pilot was conducting an agricultural survey flight when he noticed two coyotes below. To get a closer look at the animals, the pilot maneuvered the aircraft while it was in a glide over descending terrain. While observing the wildlife out the right side of the cockpit, the main wheels touched the snow-covered ground, causing the aircraft to nose over.

The accident occurred under conditions of low overcast ceilings and snow-covered terrain. These environmental factors resulted in poor contrast with the surrounding landscape, which likely contributed to the loss of visual reference to the ground during the maneuver.

The investigation

Examination of the site indicated that the aircraft had impacted the ground while descending. The pilot reported that the maneuver was initiated specifically to observe wildlife, and the impact occurred while attention was directed outside the aircraft toward the right side.

Findings

  • poor contrast between the snow-covered terrain and the sky due to low overcast ceilings
  • loss of visual reference to the ground during a glide over descending terrain
  • pilot distraction caused by maneuvering to observe wildlife

Probable cause

The pilot's failure to maintain visual reference to the ground while maneuvering in poor weather conditions, which resulted in an impact with the terrain.
