Aircraft Accident/Incident Report

Balmorhea, Texas 79718
Sunday, April 4, 2010 12:57 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was enroute to an unknown destination and was overflying a lake. The airplane was observed flying from the west at a low altitude and slow airspeed before beginning a left-hand turn toward the north. Witnesses observed the airplane descend in the left turn until the left wing tip contacted the water; the airplane subsequently impacted the lake. The airplane's right wing was not recovered from the lake. All other flight control surfaces and the engine were recovered and examined. No preimpact anomalies were detected with the airframe or the engine.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from the lake while maneuvering at low altitude.
