Aircraft Accident/Incident Report
La Porte City, Iowa 50651
Sunday, August 21, 2011 15:14 CDT
NTSB Narrative Summary Released at Completion of Accident
The accident flight was the third flight into the Phase 1 flight test program. While maneuvering the airplane at 2,500 feet above ground level through a series of turns, the pilot noticed the control stick force increase, and then he heard a bang. Following the bang, the pilot had no aileron control authority. The pilot maintained some control through rudder inputs and executed a forced landing to a field. During the forced landing, the airplane nosed over and came to rest inverted. A postaccident examination revealed one of the aileron cable swages failed due to an improper crimp by the airplane builder.
NTSB Probable Cause Narrative
The improper assembly of the aileron cable by the airplane builder.
