During a visual approach to a private airstrip, an aircraft drifted off the runway centerline due to crosswind and sun glare, resulting in a collision with a railroad sign.

What happened

The aircraft was conducting an approach to a private airstrip under visual meteorological conditions. Although visibility was adequate, the pilot encountered a crosswind of approximately 15 knots and significant sun glare from a low sun angle.

These environmental factors made it difficult for the pilot to see the runway or any obstructions clearly. As a result of the wind drift and reduced visibility, the aircraft drifted to the south side of the runway. The aircraft subsequently collided with a railroad sign located near the approach path.

The investigation

The investigation focused on the circumstances surrounding the collision. It was determined that the primary issue was the pilot's inability to see the runway or the obstruction due to the sun glare. The crosswind contributed to the lateral displacement of the aircraft from the intended flight path.

Findings

Contributing factors included:

  • Crosswind conditions during final approach
  • Sun glare impairing visual references
  • Difficulty seeing the runway and obstructions

Probable cause

The pilot's failure to maintain visual reference with the runway due to sun glare and crosswind, resulting in a collision with a railroad sign.
