NTSB summary
HISTORY OF FLIGHTOn November 27, 2013, about 1150 central daylight time, a Biesemeier manufactured Smyth Sidwinder experimental homebuilt airplane, N3786A, registered to the pilot, was destroyed when it impacted terrain after an in-flight separation of it's left wing while maneuvering over a rural area near Boulder, Colorado. The private pilot, who was the sole occupant, sustained fatal injuries. The personal flight was being conducted under the provisions of Code of Federal Regulations Part 91. Visual meteorological conditions prevailed throughout the area and a flight plan was not filed. The flight originated about 1130 from the Rocky Mountain Metropolitan Airport (BJC), and it's intended destination was Loveland, Colorado. During examination on site, the airplane's fuselage was found in a creek bed. The left wing of the airplane was located about 1/3 of a mile from the main wreckage. The wreckage was recovered to a secure facility in Greeley, Colorado for further examination. Radar data showed a normal departure and climbout from Rocky Mountain Airport during the first 15 minutes of flight, until a sudden turn and rapid descent. A witness in the area reported that he heard a loud sound, looked up, and saw the airplane falling out of the sky. Another witness reported that there were flocks of migrating birds in the area about the time of the accident. No radio calls or distress transmissions were reported from the pilot. When the NTSB investigator arrived on-scene later in the day, he observed flocks of migrating birds in the area. Recovery of the airplane wreckage was ac
Probable cause
The pilot’s abrupt maneuver, which exceeded the structural limits of the left wing and resulted in its in-flight separation.
