Sonoma Valley Airport
Aircraft Accident/Incident Report

Schellville, California 95476
Thursday, September 20, 2007 12:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot landed at the wrong airport, overran the 1,500-foot-long runway, and came to rest in a vineyard on the departure end of the runway. He mistook the accident airport for his destination, which is nearby and has a 3,300-foot runway. He also noted that the runway's wet conditions hindered breaking and caused the airplane to hydroplane. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine.

NTSB Probable Cause Narrative

The pilot's misjudgment of speed and distance, which resulted in an overrun of the runway. Contribution factors are the pilot's inadvertent landing at the wrong airport with a shorter runway than his intended destination and limited braking effectiveness resulting from the wet runway condition.
