What happened
The pilot reported being unfamiliar with the geographical area during this flight. While navigating, he focused his attention on power lines and the road below, which led to a misjudgment of the terrain ahead. He did not realize that the hill in front of him was as high as it appeared until it was too late to avoid it.
Upon realizing the proximity of the obstacle, the pilot attempted to turn back out of the situation. However, due to downwind conditions, the aircraft was blown into the hillside. The pilot stated that the wind was blowing at 10 knots at the time of the incident.
The investigation
The investigation relied heavily on the pilot's statement regarding his lack of familiarity with the area and his visual references during the flight. No mechanical issues were cited in the provided source text.
Findings
- Pilot unfamiliarity with the geographical area contributed to the inability to accurately assess terrain height.
- Failure to recognize hill height due to focusing on ground features like power lines and roads.
- Downwind conditions caused the aircraft to drift into the hillside during the attempted turn back.
Safety message
Pilots should be aware that focusing on ground references can lead to misjudgments of terrain height, especially in unfamiliar areas. Downwind conditions can significantly affect aircraft control and trajectory during critical maneuvers.
