Incident Overview
A pilot reported conducting a low approach over a runway at an elevation of 5,500 ft MSL to determine wind direction and confirm the runway was clear of obstructions. The overflight was performed at 500-600 ft above ground level (AGL). After passing the end of the runway, the airplane encountered a downdraft, resulting in a loss of 300-400 ft of altitude. The aircraft subsequently collided with trees.
Environmental Conditions
The runway is situated in a mountainous area characterized by high timbered ridges, which limit maneuvering options. During the incident, the airplane was operating with a tailwind of 8-10 mph. No other weather conditions were specified in the report.
Pilot Actions
The pilot's decision to overfly the runway at 500-600 ft AGL was intended to assess wind conditions and verify that the runway was free of obstructions. The encounter with the downdraft occurred at the end of the runway, leading to the loss of altitude and subsequent collision with trees.
Aircraft and Occupants
The source does not provide details regarding the aircraft type, registration, number of occupants, or any injuries. No information on damage extent was given.
Probable Cause
The source does not state a probable cause for the accident. The pilot's report describes the encounter with a downdraft and the tailwind conditions but does not attribute the collision to any specific factor.
