Aircraft Accident/Incident Report

Nampa, Idaho 83634
Tuesady, June 19, 2007 9:30 MDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
