Aviation Accident Summary SEA07LA173

Nampa, ID, USA

Aircraft #1

N8003U

Halsted Flightstar Pioneer

Analysis

While in cruise flight at 3,500 feet above ground level (agl), the engine of the light sport aircraft suddenly quit. The pilot therefore attempted to land the aircraft in a nearby open field. Although the initial touchdown was uneventful, during the landing roll the aircraft encountered a ditch and flipped over onto its back. A post-accident teardown of the 50 horsepower non-certificated two-cycle Hirth engine revealed that the crankshaft had fractured into two pieces.

Factual Information

On June 19, 2007, approximately 0930 mountain daylight time, a Halsted Flightstar Pioneer light sport aircraft, N8003U, flipped over during an engine-out emergency landing about 10 miles southeast of Nampa, Idaho. The student pilot, who was the sole occupant, received minor injuries, and the aircraft, which is owned and operated by the student pilot, sustained substantial damage. The 14 CFR Part 91 personal pleasure flight, which departed Nampa, Idaho, about 90 minutes prior to the accident, was being operated in visual meteorological conditions. No flight plan had been filed. According to the pilot, while he was in cruise flight at 3,500 feet above ground level (agl), the engine suddenly quit. He therefore attempted to land the aircraft in a nearby open field. Although the initial touchdown was uneventful, during the landing roll the aircraft encountered a ditch and flipped over onto its back. The owner's post-accident teardown of the 50 horsepower non-certificated two-cycle Hirth engine revealed that the crankshaft had fractured into two separate pieces.

Probable Cause and Findings

The failure (fracture) of the crankshaft of the non-certificated two-cycle engine during cruise flight. Factors include a ditch running through the field in which the pilot executed his engine-out forced landing.
