Gundy's Airport
Aircraft Accident/Incident Report

Owasso, Oklahoma 74055
Sunday, July 11, 2010 20:10 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot and passengers were on the return leg of a cross-country flight. Witnesses reported seeing the airplane approach the airfield in a left turn before losing altitude in a spin. The airplane impacted the ground in a left-wing and nose-low attitude just north and slightly east of the runway. Two witnesses added that the airplane was quiet as it approached the airport; a third witness thought the airplane’s engine was “cutting in-and-out”. A postaccident examination revealed that both wing tanks were intact and contained no fuel. The grass area underneath each fuel tank did not indicate fuel contamination or fuelblight. The firewall fuel strainer, which sustained impact damage, was absent debris and fuel. The carburetor received impact damage and two of its front attachment bolts were broken. The carburetor’s fuel bowl drain plug was removed and contained only a few drops of fuel. Inspection of the engine and propeller revealed the absence of power signatures. Examination of the engine and airframe revealed no evidence of a mechanical malfunction prior to the accident. The accident is consistent with the airplane entering a stall/spin as a result of the pilot allowing the airspeed to decay in an attempt to reach the runway in an engine-out situation.

NTSB Probable Cause Narrative

The pilot’s failure to maintain adequate airspeed during an engine-out approach to the runway, resulting in an aerodynamic stall and spin. Contributing to the accident was the pilot’s inadequate preflight planning, which resulted in a loss of engine power due to fuel exhaustion.
