Aircraft Accident/Incident Report
La Porte, Texas 77571
Monday, June 2, 2008 14:12 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot was flying the experimental homebuilt airplane with a potential buyer for the airplane who was a pilot-rated passenger. The pilot had flown the airplane 45 minutes the morning of the accident, but had not flown the airplane for the year preceding the accident. The pilot-rated passenger had no experience in the airplane. After 10 to 15 minutes of flight, witnesses observed the airplane making a climbing left turn about 1,000 feet in the air when the airplane suddenly nosed over near vertical, consistent with an aerodynamic stall. The airplane impacted an open field at a near 45-degree angle and burned in a postimpact fire. Examination of the aircraft did not reveal any preimpact anomalies.
NTSB Probable Cause Narrative
The pilot's failure to maintain adequate airspeed while maneuvering, resulting in an aerodynamic stall and uncontrolled descent.
