INDEPENDENCE, OR, USA
N8979
Schwarzler KOLB MARK 3
The pilot remained in the pattern during the aircraft's second test flight to check the flight characteristics and control responses. During a landing, the aircraft crossed the runway threshold at an altitude approximately 20 feet above the ground (agl), with an airspeed approximately 50 mph. According to the pilot, after crossing the threshold, the aircraft's left wing dropped suddenly, and the aircraft subsequently contacted the terrain. During a telephone interview, the pilot stated that he must have 'stalled' the aircraft.

The flight originated from Independence approximately 30 minutes prior to the accident. There was no fire, and no report of ELT activation. The pilot stated that no unusual difficulties were encountered during the aircraft's first test flight, which took place two days prior to the accident. On the second test flight, the pilot elected to stay in the pattern and check the aircraft's flight characteristics and control responses.
