Aircraft Accident/Incident Report
Fredericksburg, Texas 78624
Wednesday, October 13, 2010 10:00 CDT
NTSB Narrative Summary Released at Completion of Accident
According to the pilot, he reduced engine power to slow the airplane for landing while on the downwind leg of the traffic pattern. He then attempted to increase power and the engine did not respond. The pilot maneuvered the airplane immediately toward the runway and it floated during the landing. When the airplane touched down, there was insufficient distance remaining to stop on the runway. The airplane departed the end of the runway and the pilot intentionally ground-looped the airplane to stay on the airport property, causing substantial damage to both wings. A postaccident examination of the engine revealed that the clamp securing the throttle controller end was allowing the cable to slip freely.
NTSB Probable Cause Narrative
The malfunction of the throttle clamp, which resulted in the pilot's inability to control the engine's power setting.
