A pilot reported that after a normal liftoff from a farm strip with a 10-knot headwind, the aircraft stalled at 15-18 feet AGL and crashed. A thin layer of ice was found on the wings post-accident, possibly formed from melted snow freezing during takeoff.

Overview

A pilot departing from a farm strip experienced an aircraft stall shortly after liftoff, resulting in a crash. The incident occurred under conditions involving variable weather and potential icing.

Accident Details

The pilot reported that the takeoff was normal, with a headwind of 10 knots. However, when the aircraft reached an altitude of approximately 15 to 18 feet above ground level, it stalled and subsequently crashed. After the accident, the pilot discovered a thin layer of ice on the wings.

Weather Conditions

Weather at the time included sunshine, but there had been snow showers in the area. The outside temperature was estimated to be between 20 and 25 degrees Fahrenheit. The pilot noted that the sun likely melted snow that had accumulated on the wings while the aircraft was parked, and this moisture may have frozen during the takeoff, leading to ice formation.

Pilot Report

The pilot stated that he had flown 10 hours in the preceding 24 hours. He attributed the ice formation to the melting and refreezing process described above. No further details about the aircraft or injuries were provided.
